running a lvl 20 cleric, pure caster.
i dont play ToD, HoX or Vod as my lag makes me an unreilyable healer, i's not uncommon for me to still be healing a party 20 secs after harry is dead
Allways have your highst level raise slotted, parties will expect it of you
keep a stack (yes a stack) of raise scrolls and heal scrolls on you quickbar
make dam sure you have a superior potency weapon equipped, pretty much all the time
quicken - forget soloing ADQ2 without
empower healing
shield masttery - Forget soloing ADQ2 without this too
maxamise spell
highten - swapping for empower as soon as i get an apropiate shard
toughness
Spell Pen
Greater Spell pen
i think thats it.
A well played and equipped cleric is pretty dang powerfull and dam near unkillable.
mind you the blocking DR 21/ helps allot
