Frost Relic

The Frost Relic is a returning item in Risk of Rain 2.

It deals 300% base Damage every 0.25 seconds in a sphere around the holder, with a Proc Coefficient of 0.2. The radius increases by 2 units for every kill before reaching a maximum of 18 units, at which point it will no longer grow. The maximum radius can be increased by stacking the item.

As of the latest patch, the initial kill that activates the relic will also add to the base radius, meaning the effective minimum radius is 8m.

This item can usually be overlooked by most ranged classes, but it can be very useful to pick up as or. The radius is fairly small and is essentially a direct upgrade to melee DPS, though one will need to be careful not to run into any clay pots or barrels with it active. The Frost Relic's damage will cause them to explode and seriously injure the player, if not outright killing them.
