Basically pure mage build with enough stats to wield Obsidian GS. Just buff it with CMW in congregation with TCC and it should destroy. I think even R2s get the buffed damage. DB when someone is BS fishing or you need some space, that thing hurts like hell with Crown of Dusk and TSS, just don't spam it. It is easily avoidable and thus punishable with roll bs. Haven't tried this build yet but it looks promising. Armor can be changed for something more stylish when you swap Wolf ring with Havel's ring. Btw even Great magic barrier shouldn't be much of an issue if someone has it, OGS has pure physical damage ;)
