Titan Quest 2 Combustion Guide

• This skill's explosion effect is passive and automatic, triggering on-kill when enemies are afflicted with Burning.
• Pairs naturally with fire spells like  Ignite ,  Flame Volley , or  Ring of Flame to ensure reliable Burning application.
• The feat options allow you to tune the explosion’s reliability (via Chance), its radius (via Radius), or its lethality (via Damage). Mix and match depending on how often you trigger it and how you engage in combat.
