It is worth noting that as opposed to chance to critical strike, which is checked once for each cast of the skill, the chance to ignite is checked separately for each individual hit. For example, a hit from Consecrated Path linked with Combustion that hits two enemies at once could potentially ignite one enemy, but not the other.

The chance to Ignite from this gem will stack additively with chance to Ignite modifiers from other sources, such as from the Ash, Frost and Storm notable passive skill, or the stat of Firestorm. The normal rules for burning apply, linking this gem to a skill that deals no fire damage is pointless; unless the user is igniting enemies via cold damage skills with The Three Dragons or Hrimburn, or via lightning damage using Stormfire.
