Heat Burst
Tier 2Heat Burst is a Tier 2 Spirit Charm in VV: Ultimatum that replaces your Aura with Heat - activating it instantly heals 37% of your maximum health and grants max AP, but you lose your Aura-based theme buff.
Heat Burst swaps your entire Aura system for a single explosive payoff - "HE POPPED HEAT?!" With the charm equipped, your Aura is replaced by Heat; when Heat activates, you automatically heal 37% of your maximum health and gain max AP on the spot. The red-text price: you lose access to your Aura-based theme buff, the ongoing bonus your normal Aura would have provided.
The math is a burst-versus-duration question. A normal Aura pays out steadily across its window; Heat front-loads everything into one moment - over a third of your health bar back, plus a full AP bar feeding any AP-scaling effects you run. That instant reversal can flip a losing exchange outright, which is why the charm is a favorite concept for clutch-oriented brawlers rather than value-over-time players.
Logistics carry two warnings: the charm is documented as "not easily removable", so the Aura replacement is a commitment, and it requires Level 15 - slightly above the Tier 2 norm. It weighs 0 wt. and is documented as found in the Valley of Screams.
