The creature can use a spell-like ability tuned to either law, chaos, good, or evil.
Prerequisite: Spell-like ability at caster level 4th.
Benefit: Choose one of the creature’s spell-like abilities, subject to the restrictions below. The creature can use that ability as an aligned spell-like ability three times per day (or less, if the ability normally usable only once or twice per day). An aligned spell-like ability gains the good, evil, lawful, or chaotic descriptor.
When a creature uses an aligned spell-like ability, one-half the spell-like ability’s damage is of that type (evil, good, lawful, or chaotic). For example, a creature casts an aligned (evil) lightning bolt with a caster level of 6th. The aligned lightning bolt deals 3d6 points of unholy damage and 3d6 points of electricity damage. Thus, a creature immune to electricity suffers no damage from the electricity effect, but still takes 3d6 points of unholy damage.
Aligned spell-like abilities deal normal damage to creatures with regeneration if the creature’s description states that it takes damage from that type of effect (for instance, devils that are only harmed by good aligned spells and effects would take damage from a good-aligned spell-like ability). Saving throws and opposed rolls (such as the one made when a character casts dispel magic) are not affected. Spell-like abilities that already have an alignment descriptor are not affected.
For a summary, see table below.
Special: This feat can be taken multiple times. Each time it is taken, the creature can apply it to a different one of its spell-like abilities.
