You're going to want a second healer. Go for Andromeda and pick up either Granuille or Gawain for their debuff (depending on the buffs your group has access to).

if in doubt, take Andromeda. You can NEVER go wrong with Andromeda.
I got Cassio and iam pretty happy with her, just what i needed.
Didnt know that you could use both skills as Extra skills, thats nice.

Atm i run with the Vivianne skill to cure 1 affliction (nice for the Cave of Ice C...) but in the future i will aim for Granuille and her AoE debuff, should go well with shivas AoE and since i cannot control Ares (5random hits).

Thanks for the help
