Ok, so now I'm stumped with a question on using Phoenix Fire as a hero spell. Basically, I changed it into a hero spell with levels and tried to modify the intervals between the shots (DoT set to 0.01s). For some reason the spell appears to be set to the duration for level 1 only. E.g. Level 1 - 1 shot/sec, Level 2 - 0.5 shot/sec, etc. The shots at all levels appear to only shoot for 1 shot/sec. Increasing the damage does work, however. I was wondering if this is simply a mechanic of using the spell, or is there a problem, since I also noticed if you learn the spell it doesn't show up on the abilities (need to stick in a dummy ability).
