Effect groups are important because certain defenses can block any effect from its related group. For example, a Resist Command can block any effect from the Command group, whereas a Resist Curse couldn’t be used against Command effects (but would work against Curse effects).

A Purify will remove all harmful effects upon the target from the Alteration, Binding, Command, Curse, and Necromancy Effect Groups. It will also remove any Stun Limb effects. It does not cure damage caused by any of these effects.

A Dispel will remove all effects, even beneficial ones, except those in the Greater Command group and the effects Circle of Power and Ward.

Many Effect Groups contain a way to “cure” other effects from that same Group. Antidote removes all effects from the Alteration group; similarly, Cleanse fixes all Curses, Release fixes all Bindings, and Awaken removes all Commands. Other effects need specific fixes—for example, a Corrupt can only be cured via a Life spell, while an Enslavement requires the Enslavement Antidote effect to remove.
