Abilities 2 of Human
You do not need to do anything special to trigger a Self ability. When you use it, it affects you.
You either regain your Initiative or perform another ability instantly. When used in this way, you say "Haste" in place of a single incantation or three-count, such as those required for Dust, Medicine, Poison, Sign, Spell, or Supply abilities. The hastened ability becomes uninterruptible, but you must still be able to perform it normally (e.g., a Muted character cannot speak in incantation even if it's hastened). Haste can also be used to counter or end a Slow effect.
