Crowbar

The Crowbar is a returning item in Risk of Rain 2. Attacks deal 150% damage  (+50% per stack)  when attacking any enemy or boss at or above 90% health. This is equivalent to half of the damage increase (+50%) from a critical strike  (+100%) . After stacking 3 or more crowbars, the total damage dealt is greater than a critical hit. For critical strikes with the crowbar, the damage multiplier is doubled from 150% to 300%  (+100% per critical strike per stack) .

This item is best used with characters with high single-hit damage such as Loader or Captain, but all characters can make effective use of it when used with equipment such as or.

and Bands can be used to amplify Crowbar-boosted hit to deal immense damage to important targets. (If the hit that procs the band deals > 10% of the enemy HP, crowbar will not amplify the band damage)
