if something shatters via rimeheart while channeling BI, e.g. through frosties proc, will it leave black ice explosion? i dont have a rimeheart to test. if it does, rimeheart+frosties +black ice+winter flurry make a viable t6-stomping build?
Yes it works like that, just tested on PTR. Bare in mind that chance to proc rimeheart effect is very low with RoF, 10x 0.333, thats ~3% to proc.
RoF ticks very often. the proc rate per attack is around 1. (I believe RoF has a tickrate of 3). so you have ~10% per 0.7 seconds if you have no +aspd and a 1.4 aspd weapon.
RoF is speed coeff 2 and .5 proc rate. Still should work better than glacial spike (.93 and extras from mirrorball don't proc).
