Help with guild skill usage

[norirag]

There's 3 new guild skills that was implemented on kRO, one of them called Charge Shout - Beating is used by guild members, but how I make guild members able to use guild skills? I've already changed skill_check_condition_castbegin to not check if the source is a guild master but it didn't work, I've checked on other files like map, unit, pc and guild but didn't found where to enable this (or if it's on client-side), anyone knows how to do it?
