On a side note, can anyone confirm if his Master Ability's "Max HP+10%・Dark Attack+15 for all Dark allies" apply to him as well? Or does it only apply to his team members? Duane's hp doesn't seem to be affected from what I can tell.
Depends on what resistance you want to build him for?
Golem and Agiaion for pierce, Demon wall for slash, warmech for missile and Fenrir for Magic resist. Basically just build resistance to what teams you are hunting.
I will pull for him. X5 maybe..
Imagine... Having Yuna and Duane in the same team...
If you play long enough, you will pull all the non-limited characters eventually for free. So I agree. I think he looks like an interesting character, but don't waste your shards. Wait for Auron and/or Yuna.
