RE: dragon isles
Can I ask why you are not just using a berserker for a third kill? I just did a horribly unoptimal run at it and failed one hit away from kill the boss as a orc zerker.
Any number of improvements could have lead to a win: if I was a triling, if I had level 3 witch(whupaz would = guarantee but even having reflex/quicksilver prep would have), if I literally hadn't wasted 3 less tiles.
I prepped fine sword, +2 sword, health->damage, scout altar, shop scroll, 50g, burn salve and compression seal. Got GG, killed 2 level 2's, a level 3, absolution, humility, killed targets level 2-3 above me until level 7, switched to tt, slaughtered popcorn, got poison kill first born, leveled up once killing the dragons on the way to matron. If I had a little more damage(tri-ling instead of finesword/orc) I would have spent less resources on the hallway.
