Spells are active abilities with cooldown between uses that can be learned by your Keeper and some of your Minions.
Creatures who immigrate to your dungeon generally don’t have any spells, though those eligible can learn the spells from their spell school through training. Spells known are based on your Magic Damage training, with each level of training generally providing a new spell or improving a previous one (removing the previous spell, for better or worse). This also means that you will need Sorcery techs to train the spells of your minions in your dungeon, as wooden, iron and golden bookcases cap at +3, +7 and +99 Magic Damage training, respectively. While no creature in vanilla KeeperRL can train more than 12 levels in Magic Damage, mod content can and does go higher.
In KeeperRL 1.0, it’s entirely possible to improve your Magic Damage through practical combat experience. This will make your magic missiles and staff swings hit harder, but will NOT add to your spell selection.
Cooldown of spell uses is affected by your spell-speed statistic, which can generally decrease cooldowns to 50% of their original value (though some spells may be capped at longer cooldown times).
Restores the caster to full hit points, but does not restore damaged or destroyed limbs.
Restores the caster or an adjacent target to full hit points, but does not restore damaged or destroyed limbs. Does not affect Materialization.
Restores the caster or all targets in a line up to 4 tiles from the caster (including hostile targets! aim carefully) to full hit points, but does not restore damaged or destroyed limbs. Does not affect Materialization.
Restores the caster and all friendly creatures in a 2-tile radius to full hit points, but does not restore damaged or destroyed limbs. Does not affect Materialization.
Removes the POISON status from the caster. Does not restore lost hit points or prevent re-poisoning.
Removes the POISON status from the caster or an adjacent target. Does not restore lost hit points or prevent re-poisoning.
Removes the BLIND status from the caster or an adjacent target. Does not restore lost or damaged heads or eyes.
Grants the caster or an adjacent target the POISON_RESISTANT status for approximately 30 turns, removing POISON status should it be present and preventing re-poisoning for the duration. Does not restore hit points lost to any poisoning cured, though.
Knocks back everyone in a line from the caster, knocking them down for 1-2 turns, but not damaging their hitpoints. If there are any items on the ground, they will also be knocked back and into the creatures knocked back. This flung-item effect can do damage, but generally does not and should not be relied upon.
Creatures knocked back will NOT be knocked into hazardous terrain such as water or lava, instead stopping at the edge. This is working as intended.
Teleports 6 tiles away from known enemies. Does NOT check whether the destination is “safe” from other enemies or would be bottlenecked by the known enemies, though, so use with caution…
Grants SPEED_BONUS status, granting an additional movement-only action every time the creature acts. (Once Hasted creatures use their movement-only move, they must finish their turn. You may not have a Hasted creature move and then have another creature act, intending to finish the Hasted creature’s turn later in the round.) Does NOT counteract Slow.
Shoots a ray causing Magic Damage (based on the caster’s stat) up to 4 tiles from the caster, penetrating through all creatures in the way. Mages with this will NOT have learned to avoid friendly fire, so shooting through friendlies may be expected to hit, hurt, and Hostile them. (You will be warned of this fact, and given the option to abort, should you tell a creature to so cast.)
Shoots a ray causing Magic Damage (based on the caster’s stat) up to 8 tiles from the caster, penetrating through all creatures in the way. Mages with this will have learned to avoid friendly fire, so shooting through friendlies will safely bypass them. (Downed folks tagged for capture are still vulnerable, though!)
Shoots a ray causing Magic Damage (based on the caster’s stat) up to 12 tiles from the caster, penetrating through all creatures in the way. Mages with this will have learned to avoid friendly fire, so shooting through friendlies will safely bypass them. (Downed folks tagged for capture are still vulnerable, though!)
Teleports the caster to a chosen tile up to 3 tiles away. You don’t need to have sight to the tile, but you need to know that the terrain is safe.
Teleports the caster to a chosen tile up to 8 tiles away. You don’t need to have sight to the tile, but you need to know that the terrain is safe.
Grants the caster +3 Defense for 40 turns. Does not stack with Defense-boosting gear, but will stack with Thick Skin.
Turn invisible for 15 ticks.
Restores the caster or an adjacent target to full Materialization. Does not affect hit points.
Restores the caster or all spirits in a line up to 4 tiles long to full Materialization. Does not affect hit points.
Restores all friendlies in radius 2 to full Materialization. Does not affect hit points.
Summons 3 - 7 Illusions for 5 - 10 ticks.
Inflicts the PANIC status on a target (or line of targets) up to 5 tiles away, debuffing their attack but raising their defense.
Creates (temporary) fog tiles in a 4-tile radius, which block vision and ranged attacks, but not movement.
Inflicts the Peaceful status on a single target up to 2 tiles away. Peaceful creatures are considered “friendly” to everyone and cannot attack or cast offensive magic, but can be manually attacked (right-click menu), will freely swap places if moved into, and will not resist absorbption attempts.
Turn invisible; per code, no difference between this and (basic) invisibility.
Triggers the “Escape” effect similar to the spell of that name, but only looks 2 tiles away. Given the non-cooldown, this is probably better than Escape.
Summons a Chicken for 15 turns.
Summons 3 to 5 Chickens, for 15 turns.
Polymorphs the caster into a Chicken for 10 turns, during which time the chicken is Invulnerable.
Polymorphs the caster, or a single target up to 5 tiles away, into a Chicken for 10 turns, during which time the chicken is Invulnerable.
Polymorphs everyone in a 20-tile radius into a chicken for 10 turns. During this time, all such chickens are Invulnerable.
Buffs melee damage for 40 turns.
Buffs the caster or an adjacent target’s Defense for 40 turns.
Destroys all walls in a line up to 7 tiles long.
Buffs the caster or an adjacent target’s melee Damage for 40 turns.
Summons an earth elemental for 100 turns.
Buffs the Defense of all friendly creatures in a 10-tile radius, for 40 turns.
Summons 2-4 earth elementals, for 100 turns.
Buffs the melee Damage of all friendly creatures in a 10-tile radius, for 40 turns.
Summons 3 - 7 flies for 100 ticks.
Causes 3-5 corpses to float on their own and attack hostiles, for 10-20 turns. (This is more along the lines of telekinetically picking up the dead body and whacking folks with it, rather than creating more undead.)
Inflicts the BLIND status on a line of targets, up to 5 tiles long, for 5 turns.
Causes 6-5 (sic) corpses to float on their own and attack hostiles, for 30-50 turns. (This is more along the lines of telekinetically picking up the dead body and whacking folks with it, rather than creating more undead.)
