This topic is about Auto Buff Gem. You can't equip Macro skill even though you have all 3 skills that work with Auto Buff Gem in the skill macro.

Anyways, added more skills that does/doesn't work with Auto Buff Gem. THIS TIME! Non-Adventurer classes such as Aran, Evan, Mercedes, Phantom, and the ones labeled as "Adventurers" such as Dual Blade, and Cannoneer.
