Frost Bolts are a type of Ammunition in Horizon Forbidden West compatible with certain Boltblasters. They deal low Frost damage and buildup on impact.
While individual bolts deal little damage compared to arrows, they are fired in bursts of six bolts, potentially allowing for a higher damage output. All Boltblasters are capable of overdrawn shots, which can also increase their potential damage output. Frost Bolts can detonate exposed Chillwater canisters, triggering an elemental explosion freezing anything in the area.
These can be used to inflict the Brittle state on enemies, which makes them take more damage. Effective against enemies with frost vulnerability or exposed Chillwater canisters.
