Spell brimstone
NinjaKCD
A charged spell that does a cone of damage im thinking like 10 instant damage and then over the next few seconds you take burn damage 15 extra. adding up to 25 in total
Then it collapses into one beam that does 20 instant damage and then another 30 burning
I think this would be a damage class spell and unique in the fact you get burning damage as a debuff.
