„—Skill description
Spontaneous Combustion is a novice pyrokinetic skill in Divinity: Original Sin II.
Description[]
Skill[]
Spontaneous Combustion is a offensive pyrokinetic skill that allows character to hurl a fiery curse at their target which deals fire damage. The curse will cause the target, and anyone in 3 meter radius, to take additional fire damage by converting any 
Burning and 
Necrofire status effects, with the latter status granting greater damage bonus. The size of the additional damage depends on how many turns have the status effects left.
For example if the skill itself does 8 - 10 fire damage and target has Burning for 3 turns the target will take 11 points of fire damage + 4 points of fire damage caused by explosion. However if target is afflicted with Necrofire status effect for 3 turns the Spontaneous Combustion will cause 9 points of fire damage + 10 points of fire damage caused by explosion.
Since Spontaneous Combustion relies on Pyrokinesis magic it cannot be cast if caster is affected by 
Silenced and 
Enraged status effects. Spontaneous Combustion skill is NOT reflected back when the target is under Deflective Barrier skill (Definitive Edition only).
Scroll and Skillbook[]
Spontaneous Combustion skillbook is a magical item that allows its reader to learn Spontaneous Combustion skill, if they have at least 2 points into Pyrokinetic ability, and use it indefinitely. In order to be able to cast the skill, character needs 1 free memory slot. Note that the book will disappear once read. The book weights 0.5 and its base value is 190 gold. Since Spontaneous Combustion is a novice Pyrokinetic skill, traders will start selling the skillbook once Godwoken reach level 4.
Spontaneous Combustion is one of the few magic-based skills in the game that does not have a scroll.
Skill Modifiers[]
Damage of this skill is calculated with the following formula: (Base Damage) x (1 + Elemental Bonus%) x (1 + Attribute Bonus% + Weapon Skill Bonus %) x (1 + High Ground Bonus% + Crit Bonus%) x ( 1 + Misc Bonus %)
The damage of this skill is affected by the following attributes of the caster:
- Level
- Pyrokinetic ability
- Intelligence attribute
- Height bonus
- Critical Damage Modifier
Out of these the most effect on the damage have level and then Pyrokinetic ability as the latter increases damage by 5 % per point. Level provides greatest boost to the damage done. Intelligence provides the lowest bonus out of the three (3 points in Intelligence are equal to 1 point of Pyrokinetic).
When it comes to enemies they may resist fire damage if they have: Fire Immunity Status and high enough 
Fire Resistance (which lowers fire damage done).
Spontaneous Combustion properties can be affected by talents, consumable items (some of which may be affected by Five-Star Diner talent) and other skills.
