Can we get DFT back?
New sorcery keystone
Deathfire Touch
Your abilities deal 12-85 (+20% AP, +20% bonus AD) magic damage over 2 seconds. Multiple hits on one target within 4 seconds deal 50% reduced damage.
DoT abilities (must last more than 2 seconds): 25% damage AoE abilities: 75% damage
Some other creative things we can add if we want to spice it up
Bonus: Apply DFT for a total of 120 seconds (if multiple people are affected at once, all of it will count) and then remove the multi-hit damage reduction.
Bonus: Deal 4,000 damage with DFT and then give it a bonus 1% max health magic damage.
