Allow Weaponskills from off-hand weapons with 50%- damage

[Tamoa]

Just last week we held Empousa at 1% for our DRK, 2 WSs, we chose the wrong one, mob dead. It happens, not even that rarely.

In this case I'm assuming you were going for blue and it was either GS or scythe, and those are 2h weapons last I checked. And if you haven't triggered blue by 1% then it's rather pointless to try in my opinion, since 1 blue ws is likely to 1shot the mob.
