indeed. now i'm gonna have to look into some other sources... i'll get back to you. ^^
*time passes*
well. after much searching and even consulting, i too am unable to find any limitation on the surge, or even general statement of can only apply class abilities to your own class's power list... other than it has to be a power that you know. i thought for sure that there was some generic statement that you could only surge wilder powers, but it seems not so.
given the ability of all psionic characters to use power stones (which count as manifesting it yourself) and manifesting from another character's list (which still has to be on your list or it fails, but also counts as manifesting it yourself) this would mean that a multi-class psionic character of the right mix would be able to manifest all powers in the game, save only those on restricted discipline-only, or mantle-only, or lurk-only lists.
mechanically speaking, it would likely require making use of either an oddly classed character, or a character with cohorts+. perhaps less combat effective without some mild to major action-economy, and possibly some power point charging tricks.
as i recall, the limit on power points is per power, not per round, so with action and power point economy abuse, this combined with power stones and/or manifesting from other creatures' powers known would be quite an impressive scene.
so, i stand corrected. awesome job as usual, lycanthromancer. thanks for the great find. easily done pre-epic as well, if one is willing to dump feats for practiced manifester to boost ML lost to multi-classing. even the loss of higher level powers can be overcome by manifesting off of another's powers known and making the psicraft check. the only restriction is that it be on your powers known list as well.
thus the simplest method i can see would be a multi-class lurk, psywar, wilder. i suppose one should put in erudite, so as to get all of the discipline powers as well. this should cover all powers out there, missing only unique powers on non-selected mantles. psy-ref would not allow a change to mantles, as it is an alternate class feature, which classes and class features are not affected by psy-ref-ing. educated wilder could likely pick up the most useful of the missing ones. so for a build stub:
lurk 1
erudite 1
ardent 1
psy-war 1
wilder X, educated acf.
requires power stones, and/or another creature with the desired power known via leadership, thrallherd, or hireling.
i guess we should have this added as an "access all powers in the game" trick to the thread here. =D
