to target: -X power for Y seconds
to self: after 3 seconds, +X power for Y seconds
the to target -X powers bit of the power works, tested.
but when did the +X power for Y seconds on self stop working. the +X power only works for 3 seconds then it returns to initial levels, and certainly not Y seconds. btw, Y seconds is about 28s for 200 skills points (100+18*4+50~200).
