Wow.
Damp Power from CPsi to cut down the rare Healy targettings.
Short list of monsters to be psychotic'ly scared of.
Standard trickery that golems use ; heck this is pretty much the race.
That save # looks like 1st level + Con 10.
Some ways to raise that, but it'd get less useful at mid levels.
Goad and similars, to get bbe'mooks into the zone.
Intentionally take damage, like the way way back build by
Stoned Golem with negative AC , or the 4e Revenant stuff.
Hit me please, but needs to undo lots of conditions.
Might be the only defenses necessary.
I figure the combat tactic is to charge in and
mess up whatever plan the bad guys had,
while the rest of the party kites the scattering.
What kind of build does all this sound like ??
... I have totally no idea at all.
