And don't forget Lyca ...
Big Guy ... is a classic.
Ubernoob had a Lock build, just before he left (and deleted it).
The Soulbound weapon has a few strange tricks available.
There was a recent thread on what type of weapon you could get --- like a Trebuchet.
CL + ML tricks can get the most amount of Mods on it.
Mantled opens up the off-list powers, and frees up a feat slot or two.
I figure it is
always worth it when 4th level powers come around,
or maybe the very next class level after that.
It also adds higher level powers to the List, and provided a helper hangs around,
it opens up powerstones and dorjes as a get-out-of-jail combat option.
Recharge makes a PsyWar :
1 to 5 ...... slightly below average, say Tier 3 or 4
6 to 10 ... very high Tier 1
11 to 15 ... high Tier 1
16+ ... Tier 2 ish but without the 8s and 9s goodies.
If the power selection was limited in the mid-range levels, it wouldn't be so bad.
PsyWar 2 / Ardent 10 / Erudite 1 / Slayer 9 ... not necessarily in that order.
