1.)
The stat "-x.x% warp heat cost" does not effect the warp heat cost of spells, they do generate the same amount of warp heat, no matter how much of that stat I have on items

2.)
The stat "+x to warp heat decrease values of all force weapons" did not work either

There are probably more stats that do not work.

Therefore I kindly encourage all players to post stats in this thread that do not work.
