also what are you using to test 'saving throws?
Depends on what you mean.
I'm using Fort, Ref and Will as defenses in the same way as 4e, but I'm also have save ends effects that each have their own DC. So "Save ends on a 14+".
So for that kind of effect, I have several swarms, poison, etc. Not to mention spells and stuff.
For the record, here's what a monster looks like in the system (at least, v. 0.23):
Giant Tarantella Spider--- XP ?

TRAITS
Expert Biter: A giant tarantella gets a +2 bonus on attack and damage rolls with its bite attack and a +1 bonus to initiative.
STANDARD ACTIONS
Bite (poison): +5 vs. AC; 1d3+2 damage plus poison (ongoing 1d3 Wisdom damage and the target dances, moving 3 squares in a random direction at the start of each round and granting combat advantage; save ends on a 12+).
