Traits

Resistances

Magic resist

All attacks of magical nature toward the target are reduced by the stated amount (rounded down).

Non-damaging spells ( APHEELSIK, IMAWAL, WEYTWUT, WONAFYT) have a percentage chance to fail equal to the target's magic resistance. PISORF will always work unless they have 100% magic resistance.

Physical resist

All attacks of physical nature toward the target are reduced by the stated amount (rounded down).

Buffs

Death Protection

Next time you would die, you will instead survive with 1hp left, the next hit prediction box will state "Barely Alive" instead of "Death" when Death Protection is about to be consumed. If the hit will kill the monster it will predict "Barely Win" instead of "Barely Alive"

Dodge

When you take damage, there is a chance equal to your Dodge % that the next damage you take can be dodged, preventing you from taking damage.

All temporary sources of Dodge provide Dodge prediction, where the next hit prediction box will state "Dodge!" when the next attack received will be dodged.

Burning Strike

Attacks add one level of Burned to the target.

Experience Boost

Your next monster kill will grant 50% more XP, rounded down. This is consumed even by killing a No Experience enemy, granting 0 bonus XP. Any bonus experience earned from killing higher-level monsters is also multiplied.

First strike

Unless the opponents has First strike as well, the usual rules for strike order are ignored, and the entity who has First strike hits first.

Knockback

Attacks by a knockback entity will cause the target to be knocked back the opposite direction, and will cause specific effects based on the tile behind it:

A wall: the wall is destroyed, the target takes its place, and its dealt Knockback% of your base damage as physical damage.
A monster: both entities are dealt Knockback% of your base damage as physical damage.
Empty: the target is moved to the empty tile
Indestructible tile or map edge: no effect

Learning

Grants 1 extra XP upon killing an enemy, doesn't work on No Experience enemies, not to be confused with Experience Boost. Can be stacked.

Life steal

Attacking a monster heals you equal to (Life steal x your level). Attacking a lower level monster heals double the amount. The health gained from Life Steal can heal you beyond your maximum HP.

Might

Temporarily boosts your next physical attack by 30% and reduces Physical resist and Magic resist of the enemy by 3%.

Poisonous

Applies the Poisoned debuff on the target.

Sanguine

Can drink a blood pool to heal a percentage of your max health equal to the percentage of Sanguine.

Stone skin

Temporary Physical resist. Grants 20% Physical resist per charge. Removed when taking damage from a monster (including Magical attacks).

Physical resist from Stone skin still abides by maximum resistance, so you cannot raise physical resistance above the maximum.

Debuffs

Poisoned

The poisoned target (monster/player) does not regenerate HP from player exploration.

Removal: Leveling up, drinking a Health Potion or Fortitude Tonic, Glowing Guardian's Cleansing, casting HALPMEH, or equipping the Viper Ward.

Poison on monsters expires after the specified amount of tiles have been revealed.

Mana Burn

When mana burned, you do not regenerate mana from exploration and your mana is immediately set to 0.

Removal: Leveling up, drinking a Mana Potion or Burn Salve, Glowing Guardian's Cleansing, or equipping the Soul Orb.

Note: some effects, such as the BLUDTUPOWA glyph, can still restore your mana while mana-burned. These will not cure the affliction, however.

Cursed

While cursed, all sources of damage reduction and resistances you have are nullified.

Removal: Killing a non-Cursed monster (1 stack), The Earthmother's Greenblood (1 stack), Glowing Guardian's Enlightenment (all stacks)

Corrosion

Corroded targets take extra damage equal to the number of Corrosion stacks when damaged.

Removal: Burn Salve (all stacks), Glowing Guardian's Cleansing (1 stack), Jehora Jeheyu's Chaos Avatar (all stacks)

Weakened

Your base damage is reduced by an amount equal to the number of stacks of Weakened.

Removal: Fortitude Tonic (all stacks), Glowing Guardian's Cleansing (1 stack), Jehora Jeheyu's Chaos Avatar (all stacks)

Burned

One stack of Burned is applied to a monster when the attack source has the Burning trait. (BURNDAYRAZ or attack w/ Whurrgarbl). Only one enemy can be Burned at any given time.

Attacking another monster or applying an attack to the Burned monster from a non-Burning attack removes the trait, dealing Magical damage equal to the number of Burned stacks on expiration; hitting a monster with this trait using an attack which inflicts Burning will deal bonus damage equal to the number of pre-existing Burned stacks on it, then the new stacks are applied.

Maximum charges of Burned equal x2 of your current level.

When exploring tiles, a monster with this trait will regenerate HP as though it were 1 level lower than it actually is, regardless of how many stacks it has.

Slowed

The target has a slow attack speed, meaning that it will usually attack last in combat. Being Slowed also disables the following monster traits: Blinks, Cowardly, First strike, Retaliate: Fireball. Killing a Slowed monster grants a bonus of 1 XP. If a monster has been Slowed, the effect will usually wear off as soon as the monster takes damage (including from BURNDAYRAZ or PISORF).

Monster traits

Berserks

When monster's health is below the Berserk %, its attacks deal 50% more damage.

Blinks

When attacked, the monster will teleport to a random location on the map.

More precisely : if a blinking enemy is next to the player when a round of damage is finished being taken, it'll blink. Also, note that a slowed monster will not blink.

For example :

Hitting or casting a fire ball to a blinking monster will make it blink.
Hitting or casting a fire ball to a SLOWED blinking monster will NOT make it blink.

Pisorfing a blinking monster into another monster will make it blink.
Pisorfing a blinking monster into a wall or empty air, will NOT make it blink.
Pisorfing a monster into a blinking monster will NOT make it blink.

Bloodless

This monster does not leave behind a blood pool after being slain, and does not allow life steal.

Retaliate: Fireball

When this monster is attacked with a BURNDAYRAZ he will attack the caster. This retaliation deals half normal damage. Slowed monsters lose the ability to retaliate for one attack. Fireball always strikes first, and you will not suffer retaliation if you successfully kill the monster with the spell.

Cowardly

When attacked, the monster will flee the opposite direction of you if possible.

To determine whether a monster will flee or not, it will use the same rule as blinking.

Curse Bearer

Every time you kill or take damage from a Curse Bearer monster, you will gain a stack of Cursed.

Corrosive

The monster's attack applies a stack of Corrosion. When killed, it leaves a pool of acid which applies Corrosion when stepped on instead of a blood pool.
