Heat

Heat is a resource granted to all characters at the start of each round which can be spent by the usage of Heat-related mechanics. During Heat:

• All attacks deal chip damage on block.
• Certain characters may gain new moves.
• Some moves gain extra properties, either strengthening it at the cost of consuming some of the Heat gauge or having a unique property that replenishes the Heat gauge when performed.
• The Heat gauge steadily depletes until it is entirely consumed, rendering it unavailable for the rest of the round.

Mechanically speaking, there are two ways to activate Heat (Heat Burst and Heat Engagers) and two ways to spend it (Heat Smash and Heat Dash).

Activating Heat

Heat Burst

Done by inputting 2+3 or the Heat macro button without having previously activated Heat in the round. It is a large, fast, tracking mid strike that has the armor of a powercrush while also having armor breaking properties.

Unlike other Heat moves that tend to be highly character-specific, Heat Bursts are all i16, +1 on block and +2 on hit, with only a minor range difference between characters.

Heat Bursts consume a small amount of Heat on activation, giving you less of the bar to work with than a Heat Engager, and also do not grant back recoverable health. They can also be canceled by inputting a backdash (b,b) during the animation, leaving you in some recovery that is punishable at closer ranges.

Heat Engager

Done by landing specific attacks that are unique to each character. A Heat Engager can be anything from a poke to a punisher to a powercrush, and a character's available Engagers can help to define their playstyle.

Heat Engagers are always +17 on hit and put opponents into a forced guard state. Attacks can also still wallsplat and balcony break if the move has such properties, even after Heat is triggered, allowing for potential follow-ups into Heat Smash or Heat Dash.

Upon landing a Heat Engager, the character gains back a portion of their recoverable health.

Consuming Heat

Heat Smash

Done with the same input as Heat Burst. A Heat Smash is a powerful attack that consumes your remaining Heat gauge to maintain plus frames, break armor, or mix the opponent up if your character has a Heat Smash' that is a low.

Mid Heat Smashes are plus on block and have varying startups and tracking, while low ones are typically unsafe and potentially punishable. Though most characters only have a single Heat Smash, characters with stances sometimes have a unique extra one performed from said stance.

Heat Smashes heavily scale down in damage quite heavily if used during a combo and thus not preferred to end combos with over Heat Dash.

Heat Dash

When a Heat Engager is used while already in Heat and forward is held as the move connects with the opponent, your remaining Heat gauge is consumed and a Heat Dash is performed. This has ample utility in both pressure and combos, as it forces plus frames on block and unique combo extensions on hit.

Throws that are Heat Engagers cannot be used to Heat Dash. The frame data of each Heat Dash varies on hit, but on block they are universally +5g, +18w.
