I tested with the precast and it did nothing. Looks like I was wrong. I'll be changing my opening sequence, I guess. :x
Edit: WAIT. I have an idea. If you precast searing totem, then run my rotation, the AI from searing totem may carry across to the FE totem as it did that first time I tested. Inc results, lol.
HAH! It does indeed.
So my new opening sequence is (lol):
1. Cast Searing Totem (potential, actually, for a searing totem tick here as well between the LB hitting and the FE cast on #6)
8. Ascend (+lust)
Incidentally, Sarac, I had missed that you cast EB along with a SL, which is significantly longer than 3 seconds. Which means you could potentially proc twice, although it's quite unlikely. Basically the same chance as this opener to proc once during the SL and Ascend pop. Using PE gives a lot shorter time for the opening sequence.
