Creature will perform two Melee Attacks instead of one against the same target next attack (at least one friendly creature from this friendly stack must be killed before this rune can be placed on it).

The effect is active until the stack's next melee attack. If the enemy stack is killed with the first blow, then the rune effect stays active.

Creature speed increases by 100% until the end of the turn.

Creature will have a chance to steal random positive effect imposed on the enemy target in attack once.

On its next melee or ranged attack, the stack will steal a random Light Magic blessing from its target (even Magical Immunity). If no such effect can be stolen, the rune is wasted.

Dispels all the negative effects imposed on the creature (only those that can be dispelled basically).

Level 1-3 Dark Magic curses will be dispelled, as well as certain other negative effects (like the Master of Fire "Burn" effect). "Poison" will not be dispelled.

Creature gets incorporeality for one turn.

Creature gets immunity to two random magical elements until the end of combat.

Each time the rune is used on a stack, two new elements are randomly selected.

Ressurects 40% of killed creatures in the stack.

Selected creature will have a chance to inflict the Thunderclap effect to the enemy in attack once (the target will lose its Initiative).

The rune is active until the Thunderclap effect triggers. The triggering chance is the same as for some creature abilities. It can trigger on attacks and retaliation strikes, and is improved by Soldier's Luck.

Creature gets +100% to its Defense, +100% to its attack and +50% to magic-proof for one turn (doesn't work for Dragons).

The raw Attack and Defense values of the stack are doubled (not the bonus coming from the hero, spells or other effects). For example, a stack of Bear Riders will always gain +5 in Attack and +10 in Defense, whatever their current stats.

Creature will have a chance to perform a Melee Attack against all nearby enemies once (no retaliation).

On its next melee attack, the creature will be able to attack all the adjacent enemy stacks, without retaliation (equivalent to the Deep Hydra's six-headed attack ability). If the creature also has an active Rune of Berserking, then both effect will trigger, and it will strike all adjacent enemies twice.
