A dispel check is a roll of 1d20 + caster level of the character making the attempt to dispel (usually used with dispel magic). The DC is 11 plus the level of the spellcaster who initiated the effect being dispelled.
Bug Notes Edit
The formula used is different from the one advertised, what is taken into account is the character level and not the caster level of each effect:
Caster roll: 1d20 + Caster level (capped appropriate to each spell) Dispel DC: 11 + Character level
