Red Death works, so Suros should also work. The only person that should really need the healing though is the Sword user... so let him have the Relic (Chalise of Light). Everybody else just needs to avoid getting hit (not hard). The main problem with Red Death or Suros (I assume) is that they take up Exotic weapon slot. You are better off having Ice Breaker or Gjallahorn as your Exotic (if you have those).
