When a piece of Nethengeic armor is worn, the player will deal 10% more damage to mobs set on fire. Every type of weapon is affected by the increased damage against ignited mobs. Wearing more pieces of Nethengeic armor will further increase damage dealt to ignited mobs, to increments of 20%/30%/40% more damage- depending on how many pieces are worn.
Wearing a full set of Nethengeic armor will additionally increase the player's damage by 50%- if they are on fire. If the player attacks an ignited mob while they are on fire, then the full set boost will be applied after the per piece damage boost. E.G. a weapon that deals 10 (×5) damage will first be increased to 14 (×7) damage, then the full set bonus will increase it by 50%, making the final damage output 21 (×10.5) damage.
