Dispell
From The Five Pillars
Dispelling spells means using mana to remove them from your kingdom.
The amount of mana you need to dispell a spell depends on your spell_level compared to the enemy's spell_level and the base mana costs of the spell in question. (Base mana costs of a spell is the total casting costs in mana of the spell in question as displayed on help page.)
In order to calculate the mana neccessary to dispell a spell use the following formula:
caster SL / your SL * 2 * spell's base mana costs
It's also commonly said that the mana color you dispell with affect the mana cost.
So that for dispelling with allied color mana (allied to the color of the spell) you need
multiply the base mana cost by 1.1 and for opposite color mana 1.25.
Note1 : Some spells are undispellable!
Note2 : Spells cast by yourself take 0 mana to dispell.
Note3 : You may dispell with any combination of different mana sorts
Note4 : Spells can also be dispelled by attacking the caster (there is a chance of failing)
