Heaven Cracker

The Heaven Cracker is a item in Risk of Rain that causes one basic attack per every four basic attacks to pierce through enemies for 100% damage. It stackable up to 4.

Character Synergies
The Huntress being always on the move while attacking can proc this item more often than other classes.

HAN-D can exploit the ability of this item to recharge his OVERCLOCK ability almost completely, if used against large crowds of enemies.

All melee characters gain infinite range each fourth attack thanks to this item making it much more valuable on these classes.

Commando's basic attack only pierces on one of the two shots. This means that he ends up dealing 160% damage, and because the Heaven Cracker shot can crit and apply other on-hit effects, there is actually a chance of applying such effects TWICE in one attack, whereas the default commando attack can only proc effects once per volley.

"Non-synergy" CHEF's basic attack pierce enemies by default, dealing a little more damage on the return back. Making this item not only useless but a downgrade from the default. It makes this item less effective than on any other character.

The piercing beam replaces the Engineer's grenades when triggered.

Item Synergies

 * The Heaven Cracker synergizes well with all on-hit items since the effect will proc on every enemy.
 * Maybe the best example is the Brilliant Behemoth because of the explosive blast being multiplied by the number of enemies hit allowing the user to dispose of large groups in one shot.

Trivia

 * This item is a reference to the Studio Gainax anime series Tengen Toppa Gurren Lagann, where one of the main characters, Simon the Digger, exclaims "My drill is the drill that will pierce the heavens!"
