Flame bursts up from the ground in front of you. Each upgrade level adds another burst of flame in front of the previous ones, up to a total of seven. This is more powerful than vine magic because it has the same amount of hits at the same speed with damage over time. It's a great boss slaying splash attack, and it's very useful for heavy enemies, who take normal knockback from all fire based attacks.
This attack is among the most broken, possibly the second or third most powerful attacks in the game. The reason is because it's a reskin of Brute and Snakey's splash attack, with slightly more range, which is already thought to be one of the best, but this attack adds fire damage over time on top of that speed, which make fire demon an extremely overpowered/broken character.
A ball of fire trailing orange smoke. The fire DoT effect adds a nice bonus, with the downside being the fire element itself, meaning some enemies will resist it. Uses a yellow and orange smoke color scheme as opposed to the yellow and black smoke colors of Orange Knight's "Fireball", but otherwise the same spell.
Leaps up with yellow and orange flame billowing out below, lighting enemies on fire. The same spell as Orange Knight's "Fire Jump" except graphically (the knight's "Fire Jump" uses yellow flame with black smoke and this is yellow with orange smoke).
