No. Ok, cast WW accrue 5 Threads, Cast Rift.. 8 Threadlings go out, Cast WW to accrue 5 more.. While you recast, the 8 Get reduced damage... so you now must stay in normal plane of existence and wait for all the Threadlings to die or they have reduced damage when you re enter WW.
Oh, so its specifically only while in ww that the threadlings deal reduced damage? I thought it was specifically any threadlings made while in ww.
