Spell help text refers to the wrong effect or ability

Your ability or effect description (spell tip) may appear different to the description of the spell on the Troop's card in Gems of War. There are a number of troops that are like this, but it's not actually a bug - the box's tip is pointing to some design or code in the back-end of the game.

For example, Fire Bomb destroys himself but in order to do so he must Dispel in case Barrier is active.

Note: If the troop is otherwise working as the spell describes but the spell tip is simply different, don't worry. This designed to ensure that the Troop's spell works correctly without causing odd issues.
