Iron Flesh is a Pyromancy in Dark Souls 2. To cast a Pyromancy, you must use a Flame or Special Weapons that can cast Pyromancy.
"A pyromancy that internalizes the power of flame. Turns the body into iron. Increasing defense and resistance.
As one might guess, the rock-solid flesh enabled by this spell dramatically slows movement.
Guaranteed to cause trouble if used at an inopportune moment."
- From Rosabeth of Melfia for 3,500
- Makes the user incredibly slow, but increases defense and resistances.
With enough VIT, it is possible to fast roll with it. The Royal Soldier ring and the Third Dragon ring help greatly for this purpose.
This spell lasts for 25 seconds, 35 seconds if the Lingering Dragoncrest ring +2 is equipped and 40 seconds if the full Northwander Set is also equipped.
Seems to add 65 weight, confirmed, does add 65 weight -ACEXULTRA.
Adds 100 physical defense, 200 elemental, 200 resistances, 100 poise and a damage reduction far superior to Numbness.
