Overburn is a debuff applied by some Shademancer cards. When a card on the field has more Overburn than 
health, it immediately explodes, dealing damage equal to its Overburn to itself and all its allied cards in that row.
Information and Strategy
Overburn is an effect exclusive to the Shademancer Tribe. It is a unique debuff that has no immediate effect on the afflicted enemy, but instantly kills it once the health threshold is passed and damages its enemies as well. This makes Overburn very useful for cleaning up multiple weak enemies quickly, but causes it to fall off in effectiveness against enemies with a lot of health.
Overburn Interactions
Clunkers have no health at all, since they have 
Scrap instead. As a result, a Clunker will immediately explode when inflicted with any amount of Overburn. The Clunker itself will only lose 1 Scrap from the explosion, but the damage dealt to its allies in the row will be equal to the Overburn stacks, as normal.
If a card survives its own Overburn explosion (due to 
Shell, 
Block, or Scrap), the Overburn is removed after it explodes.
Checking if a card should explode from its Overburn is a high-priority action. It is checked between 
Frenzy attacks and before 
Reactions trigger. For instance, if a card attacks another that has Smackback, but the attack causes the card's health to become lower than its Overburn, it will explode before it can counterattack. If it survives its own explosion, it will still counterattack.
