Level 1
Oct 29, 2008
I'm making a map that contians Waves(Like TD maps) and i have a Shrine for a Support in Mid-game.He is able to cast spells sometimes killing all units in a lane, but some Waves are Special, like Bosses,Leaders,Specials... whatever and i don't want to make them killable from Shrine Abilities, so i thought about a trigger that make a Temporary Disabled Ability

A trigger that makes a specific Ability disabled in Shrine on Example: "Level 40 - Boss", after ending this Wave all Abilities back normal and make able the usage of the abilities again.
