Crowbar

The Crowbar is a item in Risk of Rain that allows the player to deal more damage to healthy enemies.

Effective Health formula
Players may consider this item as a direct reduction on enemies health diminishing it to 93.4%

To calculate the effective health of an enemy for every other crowbar after the first use the following formula: 100 - { [ 0.50 + ( 0.30 x n°crowbars_after_the_first ) ] x [ 20 / ( 1 + 0.5 + ( 0.30 x n°crowbars_after_the_first ) ] }

In the case the player isn't using an ability that deals heavy amounts of damage, the Crowbar will have less and less impact on the damage output.

Character Synergies
The Sniper makes excellent use of the Crowbar, as it pairs well with to deal severe damage to newly spawned monsters and bosses. The Bandit can also make good use of the Crowbar with, dealing heavy damage to targets.

Commando, having FMJ skill, can be overpowered when he makes use of the Item Synergies of Crowbar.

Trivia
The Crowbar item is a reference to the Half Life series created by Valve, in which the main character "Gordon Freeman" uses a Crowbar very similar to the one in Risk of Rain as his melee weapon. The text "Until the 3rd version arrives" is a dig at the long production time of the half life series and Valve's seeming dislike of the number 3, going as far as making Half Life 1, 2 and Half Life 2 episodes 1 and 2. Because of this, Half Life 3 has become a well known point of humor on the internet joking about how it will never come out.
