Shuriken

The  is an item in Risk of Rain 2, added in the Survivors of the Void expansion.

The item grants the buff, which stacks up to 3 (+1 per stack) times over 10 seconds. When the holder's primary skill is used, a shuriken projectile is launched forward at the same time, dealing 400% (+100% per stack) damage with a 1.0 Proc Coefficient and consuming one stack of the Shuriken buff.

Math
The charge cooldown is determined by the formula $$f(x) = \frac{10}{(amount + 2)}$$.

Tips

 * Shurikens on melee-based characters like or  can give them a ranged attack while activating their primary.
 * However, does not gain barrier from Shurikens, as her passive only affects her gauntlets.
 * Shurikens on are harder to utilize, as they activate as soon as he charges his primary, rather than when he releases the shot.
 * The lock-on attacks for can activate Shurikens, but will only work with a target in sight.
 * A single stack of Shurikens deals enough damage to activate the, , and , allowing characters such as and  to more consistently activate them. Conversely, characters with strong single-hit skills can lose out on damage output if Shurikens activate bands instead.
 * Notably, Engineer's turrets can use Shurikens with their attack, allowing them to use the Bands as well.
 * Shuriken stacking has both diminishing and quadratic returns. One stack of Shurikens can deal 1200% base damage per ten seconds. A second stack only increases this by 800% base damage, however each additional stack adds 200% more than the last (D=(x+200%)(x+300%)), as both the number of shurikens and the damage they deal increases.
 * This means that while Shurikens might not stack well normally, if you find a printer, they can become extremely powerful. At six stacks, the quadratic damage growth will get a very considerable return. However it's still not enough to cancel out the diminishing returns of stacking unless you can find sufficient stacks of Shurikens. Going beyond six stacks can increase your DPS by leaps and bounds.
 * Shurikens are extremely dangerous if monsters gain them (such as in the, with the enabled, or if the monster is a  or the ), as they deal large amounts of damage and are difficult to avoid due to their high velocity. If the monsters also have Kjaro's or Runald's Band, even a single shuriken can kill the player.
