Binary spells are spells which can only have full effect (hit) or no effect (resist); partial resists are not possible. Normally, damage spells are only binary if they have an additional non-damage effect. Some examples are Death Coil, and Mind Flay. Frostbolt is no longer a Binary Spell.

For binary spells, both spell penetration and spell hit rating can be used to overcome resistances.

DoTs used to be binary spells, but this was changed.
