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 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 pseudo-ranged attack when charged.
 * 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.
 * Due to relying on lock-on attacks for her primaries, Shurikens can be harder to use for her since the primary cannot be used without a target, and the Shurikens require manual aim.
 * A single stack of Shurikens deals enough damage to activate the, , and , allowing characters such as and  to more consistently activate them without setup. However, characters with strong single-hit skills may want to steer clear of the Shuriken so that they can be sure to activate the Bands on large hits and reap their full benefits.
 * Shuriken stacking has both diminishing and exponential 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, 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 exponential damage growth is enough to cancel out the diminishing returns of stacking. Going beyond six stacks can increase your DPS by leaps and bounds.
