About 4 days ago I got my mage to 80 and respecced fire (cookie cutter TotW spec). In fire gear and with a crit trinket my crit chance is about 40% or more depending on the spell I'm using. What I'm wondering is, if I have Ignite on a target from something like a Hot Streak crit and I get a crit with Living Bomb or Scorch or something, does that smaller spell overwrite my huge Pyro crit? Or do they stack/absorb into one? If it does overwrite, should I be modifying my rotation around what spells have critted?
Secondary question - does my Hot Streak casted Pyro contribute to the next Hot Streak if it crits?
Thanks so much for some insight!
