Casters Gain TP from casting spells

[Alhanelem]

an ability like sublimation that converts tp gained per tic, when used again it dumps all the tp back to the user(maybe at half the drain rate 2tp stores = 1 tp back?). so you got tp for a ws(mykr/spirit taker)(or any other ability that uses tp if they ever add more then just for dancer).
Conclusion: occult acumen (as well as any stray regain spell or effects) are converted into something useful every so often w/o the major sacrifice of your staff bonus

There already do exist items that drain your TP to do something. That doesn't make there be any harm in functional weapon skills on staves being of utility to a class that isn't good at melee. But being able to use them shouldn't have to come at the cost of having to use an inferior staff for your normal activities.
