How about being able to adjust your skill/spell speed somewhat, by paying
more/less sp/ep?

This could be separate skillspellability whatever, i.e.

cast identify at foo try faster
+50% spellcost, -25% rounds

cast identify at foo try slower
-25% spellcost, +50% rounds

or something, and maybe something similar with skills too. At least I think
it\'d be fun, shrug.
