Combust

It is a part of Terra's Pyro loadout.

Strategy and Synergy
Combust provides the burst damage potential that Flame-based decks typically have a lack of, making it sometimes a must-have when you want to start making a Flame build while also being able to survive the enemy as fire damage chips down their health, which would only become more relevant as they make progress on Hell Passes. The more Flames on the field, the larger the area of impact that this spell will have, and the easier it is to hit the enemy with it. This can be a double-edged sword however; if the player is setting their own tiles on fire anyways, they are more prone to accidentally cast it at an inopportune time thus dealing a hefty chunk of damage to themselves. For this reason, and  does not exactly synergize well with it, unless the player themselves can manage despite it.

This spell works extra well with other cards that create more fire, such as and  as they can easily spread Flame to maximize the area of effect radius of it.
