Introduction

Corona: Realm of Magic is a rogue-like computer role-playing game.

It serves as a platform on which the author can air his opinions about rogue-like games.

Many games throughout history have inspired and otherwise fed into Corona: the "old-school" games like Wumpus, Colossal Cave[/Adventure], and Dungeon[/Zork]; the classic roguelikes like Rogue itself, [Net]Hack, Moria[/Angband], as well as more recent roguelikes like AlphaMan, ZZT[/Megazeux] and ADOM; commercial CRPG's have some influence on it as well, from earlier game series like Ultima, Bard's Tale, and Pool of Radiance, to more recent ones like Final Fantasy, Dungeon Master [Amiga], and Diablo.

Corona is built on the CARPE DIEM game engine. (In fact CARPE DIEM evolved out of the original Corona.)

Game Overview

You command a band (or bands) of adventurers who set out to find fame, fortune, riches, experience, and excitement in a relatively open-ended fashion.

The World

Corona: Realm of Magoc is set in a large fantasy universe, primarily on a newly- colonized and largely-unexplored continent where magic forces abound and various groups vy for power.

Civilization has barely yet gotten a foothold on this world that the explorers call Aelia, the new world, and the residents call Q'lob Stehlm, their ancestral homeland.

The larger settlements, like Bakersport and Saiphan, have become walled cities, keeping the noblemen and women safe from the rampaging hordes of grotesques and spririts, but leaving the farmers and peasants in the surrounding countryside without support; only their savvy and pioneer spirit remain to help protect them.

Meanwhile the nomadic native creatures are adapting to this intrusion, forming camps and strongholds of their own, as their far-superior knowledge of the countryside allows them to conceal their machinations extremely effectively.

Ability Stats

All creatures, monsters and characters alike, have important attributes which are generated randomly upon their creation. These attributes are called ability stats and are chosen for human beings as the sum of three six-sided dice rolls (rolls for other beings are usually based on this as well, with certain tradeoffs.)

Each creature has a maximum value for each stat, as well as an operating value. An operating value lower than a maximum value indicates that the creature has sustained some manner of injury, be it physical, mental, or spiritual. When allowed to rest, operating stats will tend to heal back towards (but not beyond) the maximum stat. Operating stats can also be boosted above the maximum stat temporarily; they will fall back to the maximum stat in time.

The stats are:

• STRENGTH. A measure of the raw muscular strength of the creature. Extreme pain and weakening agents such as poisons subtract from operating strength. An operating strength of zero indicates a creature is too weak to move. A negative operating strength will kill a creature by means of complete muscular atrophy.
• CONSTITUTION. A measure of the physical makeup and endurance of the creature. Physical damage subtracts from operating constitution. An operating constitution of zero indicates a creature is too wounded to move. A negative operating constitution will kill a creature by means of fatal wounding.
• DEXTERITY. A measure of the agility and overall swiftness of the creature. Constriction and cold attacks subtract from operating dexterity. An operating dexterity of zero indicates a creature is too constricted or frozen to move. A negative operating dexterity will kill a creature by means of strangulation or crushing.
• INTELLIGENCE. A measure of the overall reasoning capabilities of the creature. Psychic attacks and critical head hits subtract from operating intelligence. An operating intelligence of zero indicates a creature is too senseless or brain-damaged to move. A negative operating intelligence will kill a creature by means of brain death.
• SPIRIT. A measure of the overall spiritual balance of the creature, also related to the awareness, alacrity, and ego of the creature in general. Casting commonplace magical spells subtract from operating spirit. An operating spirit of zero indicates a creature is too exhausted or depressed to move. A negative operating spirit may subtract from the creature's maximum constitution.
• CHARISMA. A measure of the likeableness and natural ease with the creature interacts with others, also related to the cunning of the creature. Peer/community pressure, disfiguring (acid) attacks, and acquiring unpleasant scents subtract from operating charisma. An operating charisma of zero indicates a creature is too bitter and twisted to do anything except inspire fear and loathing on sight. A negative operating charisma cannot be achieved.

Combat System

Melee Weapons

A character may only engage in melee with a weapon in their dominant hand unless they have a talent at two-handed combat. Ambidextrous characters may change what their dominant hand is at any time by switching stance. Without a weapon readied in the dominant hand, a creature will use its body weaponry (which in the case of humanoids consists by default of a single punch.)

A weapon has one or more attacks. For each attack several values are associated: the accuracy of the attack (bonus modifier added to the to-hit roll,) the potental damage (as dice with a bonus modifier,) and the makeup of the damaging blow in terms of elements, for determining scaled damage based on resistance.

In addition, the item itself is made of up elements. These elements determine (upon object creation) various properties of the weapon itself. These properties include color, density (scale of weight), and hardness (implemented as resistances on the item itself.)

A reflexive talent of weapon proficiency may be acquired and improved for each class of weapon (sword, quarterstaff, and so forth.) A successful use of this talent effectively gives the character a second to-hit roll.

Armour

Armour, which includes clothing, are items which can be wielded on places other the hands.

Each piece of armour has a coverage value, which is the percent of the region it is worn on that it protects. It also has a condition value which describes how damaged it is.

In addition, the item itself is made of up elements. These elements determine (upon object creation) various properties of the armour itself. These properties include color, density (scale of weight), and hardness (implemented as resistances on the item itself.)

Initial condition (durability) is derived from weight (base weight times density.) Each strike of weapon on armour damages both the weapon and the armour. Each is subject to resistance from the other based on the elements in play.

A reflexive talent of armour use may be acquired and improved. for each class of weapon (sword, quarterstaff, and so forth.) A successful use of this talent effectively lets the roll on coverage to be taken again.

Guilds

The residents of Aelia are no strangers to the idea of the division of labour. Many organizations, both religious and secular in nature, attract many adventurers who rise up their ranks in their pursuit of fame, power, and riches. These guilds provide training and standing for their members, for a fee.

Training involves both physical and personal development, as well as acquiring and improving talents.

With respect to personal training, each guild is associated with an ability stat called the prime desired stat. Some guilds also have another ability stat called the secondary desired stat. As a character climbs the ranks of a guild, at a rate determined by the guild, they are offered the opportunity to permanently enhance these ability stats.

With respect to learning talents, each guild protects a set of skills which it grants to its members as they rise in rank. While the use of these talents is not restricted to guild members, some are protected by the guild, such that the costs or chances of non-members acquiring them are prohibitive. Each talent is only available at a certain guild rank and above. Once acquired, the talent may also be improved in lieu of learning a new talent (if one is available.)

The Basic Six Adventurer Guilds

• SOLDIER. Warriors who are used to looking at the world from behind the haft of a drawn blade. It's not a pleasant or easy job but there's rarely a problem finding work.

  The prime desired stat of the soldier is strength. Soldier talents include combat theory, assorted physical conditioning skills, weapon and armour familiarity, assorted combat manouevers, and some defense and survival techniques.

• RANGER. Patrolmen who are relied upon to scout and explore the wilderness, often on horseback. Esteemed for upholding the "tough cookie" image through thick and thin.

  The prime desired stat of the ranger is constitution. Ranger talents include wilderness survival, identifying flora and fauna, hunting and fishing, trapping and skinning, as well as archery and horseback riding.

• THIEF. Dodgy, nervous individuals who like to think of themselves as simply pursuing alternative strategies to making a living.

  The prime desired stat of the thief is dexterity. Thief talents include picking pockets, picking locks, detecting and disarming traps, moving around unseen and unheard, and surprising unwary creatures.

• MAGE. A student and scientist of magic who seeks naught but to unlock the unseen forces of the universe.

  The prime desired stat of the mage is intelligence. Mage talents include magic theory plus various spells. The mage guild protects a rather broad, general-purpose assortment of spells, rather than any specialization. The spell types include attack spells, defense spells, transmutation spells, and escape spells, with the occasional detection spell and such thrown in for good measure.

• CLERIC. One of those that believe themselves to be the truly devout. Each cleric worships a diety and belongs to a religious establishment of fellow worshippers.

  The prime desired stat of the cleric is spirit. Cleric talents include various prayers; exactly which ones depends on the diety, but the prayers often deal in protection, divination, and healing, as well as blessing and cursing items, people, and locations, and turning or commanding undead beings.

• BARD. The entertainer who considers themself an artist with a taste for adventure; everyone loves a bard, and bards love to party.

  The prime desired stat of the bard is charisma. The most notable bard talent is playing a musical instrument, but dancing and acting are also valuable skills, as are more academic studies like music theory.

  Due to the magical nature of the world, experienced bards can impart spell-like mind-altering effects with their music, such as causing sensations of fellowship, enmity, fear, placidity, and drowsiness - but these enchanted tunes cannot affect those that cannot hear them.

The Fifteen Extended Guilds

  The prime desired stat of the paladin is spirit, the secondary desired stat strength. Prerequisites for entrance to a paladin guild are an nth rank attainment as a cleric and an nth rank as a soldier.

  Druid talents include all cleric and ranger talents, as well as various druidic studies such as herbalism and geomancy. Druidic prayers include communing with plants and animals, and extremely powerful druids can control the weather as an awesome attack magic.

• MONK. Cloistered clerics who devote their lives to upholding their faith and protecting their monestary.

  The prime desired stat of the monk is spirit, the secondary desired stat dexterity. Prerequisites for entrance to a monk guild are an nth rank attainment as a cleric and an nth rank as a thief.

• NINJA. Experts in moving about unnoticed and often employed as spies, the ninja use subtle magicks to aid in their stealthy assaults.

  The prime desired stat of the ninja is dexterity, the secondary desired stat intelligence. Prerequisites for entrance to a ninja guild are an nth rank attainment as a thief and an nth rank as a mage.
