Oh yeah sreservoir , recharge is fun!
side note, but apparently wild surge works on any power you know, not just those from your wilder list. so if you multiclass into psywar, you can surge all your psywar powers known too. and with power stones working as if you manifested it (unlike scrolls), and the ability to manifest another's powers, you don't even have to take that many levels of psywar either.
add a level of erudite, lurk, and ardent for even more craziness.
While this wasn't where I was going, it is good.
Wilder 2 can have Magic Mantle mga. Divine Mind 1,
Mantled PsyWar 2, Ardent 1 and Mantled Erudite 1, but not Lurk.
Whichever Psion 5 can get the Life Mantle (acf feeling lazy) can do it soon after tho' pricey.
I was thinking more about Spells in general, "tossed" over to the Wilder.
Like this list, in case a Wilder could use one (or two) better
