Someone using it in NM Dungeons.
I used it quite differently.
Toss down a few Fire Walls, then Incinerate. Fire Wall increases burning damage by x25%. Aspect of Conflagration increases burning damage up to x30% while channeling Incinerate. Using Fire Wall as an Enchant will allow Incinerate to proc even more Fire Walls.
Pretty easy to take on an entire screen of enemies and leave with Full Health due to how Warmth works.
You can do WT4 Hell Tides without a problem, but it won’t scale well for high level NM Dungeons.
