Flame Reave Catalyst of Fire fireball procs don’t work with Embers on the fireball tree - tested for a couple of minutes and I’m convinced I only saw a single fireball fly out (if it matters, I was using Seeker’s Ash - I didn’t test without that)
Focus
Energy Infusion shows the same movement speed boost with 1 point or 5 points - feels like there is no difference in movement speed between them either
Null Profusion gives energy even when energy starts above 0 (Null Infusion also seems to work)
