Heat Sink

Heat Sink is a gem effect in Xenoblade Chronicles and Future Connected. It reduces the amount of talent gauge or  gains. If equipped to another character, it has no effect.

Overview
As Sharla and Kino are the only characters that don't necessarily want high talent gauge, they get their own version of Talent Boost. Heat Sink allows them to go longer without having to cool off, and use more arts at higher effectiveness, while also making it more difficult to get to high heat for high.
