UPDATE: I added a second build for him, more of a damage dealing weapon build

Still not entirely positive on Ardan's role. Trying to use him in almost the same way I use Catherine, just with less stuns haha. Seems to be doing decently though so I will update when I know more!

Update: I'm liking him as a bit more of a damage dealer. He doesn't have the stuns of a Catherine so his support role is secondary. Using his first skill to get his vengeance up quickly and spamming blood for blood is super powerful. Especially if you can use his last skill to single out and cut off the weak members of the herd. He is a super effective counter to Taka when you combine him with Catherine. That combo is ridiculous.
