Spirit PowerGive feedback

Spirit Power is a stat that increases the effectiveness of abilities and items. In addition to increasing Spirit Damage, Spirit Power can also increase miscellaneous ability attributes that are not otherwise broadly covered by spirit stats. Spirit Power is generally useful on all heroes, but some will benefit much more than others due to better scaling coefficients.

Spirit Power Scaling

The upward trending purple arrow and spirit star indicate this damage is increased by spirit power.

When an ability or item can be scaled by spirit power it will be indicated with a purple upward trending arrow and the spirit star icon. The effectiveness of spirit power on a given ability is based on its spirit power coefficient shown after the spirit scaling icon e.g. x0.5. Using that spirit power coefficient, spirit damage can be represented with the formula:

$𝑆 𝑝 𝑖 𝑟 𝑖 𝑡 𝐷 𝑎 𝑚 𝑎 𝑔 𝑒 = 𝐵 𝑎 𝑠 𝑒 𝐷 𝑎 𝑚 𝑎 𝑔 𝑒 + (𝑆 𝑝 𝑖 𝑟 𝑖 𝑡 𝑃 𝑜 𝑤 𝑒 𝑟 * 𝑆 𝑝 𝑖 𝑟 𝑖 𝑡 𝑃 𝑜 𝑤 𝑒 𝑟 𝐶 𝑜 𝑒 𝑓 𝑓 𝑖 𝑐 𝑖 𝑒 𝑛 𝑡)$

For example, Lash Flog ability deals 65 base damage and has a spirit power coefficient of x1.18. In a case where it was being buffed by 20 spirit power, the calculation would be as follows:

$𝑆 𝑝 𝑖 𝑟 𝑖 𝑡 𝐷 𝑎 𝑚 𝑎 𝑔 𝑒 = 65 + (20 * 1.18) = 88.6$

In general this represents linear scaling, with the rate of increase being determined by the spirit power coefficient. In most cases, the spirit power coefficient can be obtained by hovering over the skill while pressing the Extra Info hotkey.

WARNING: Obtaining exact calculations can be difficult because the spirit scaling values are rounded to the nearest tenth. This can lead to inaccurate calculations when trying to apply the above formula. In general, it is possible to obtain good approximations of spirit power's affect on damage but exact calculations often require sandbox testing to obtain the un-rounded scaling values.

Hidden Spirit Power Coefficients

For items, the spirit power coefficient is not currently shown, making it difficult to determine if and how effectively they will scale. In general, if an item deals spirit damage, that damage will scale with spirit power. Other properties of items such as inflicting Fire Rate slow or negative Bullet Resist do not currently scale with spirit power, even if they are produced by a spirit item.

Because the spirit power coefficient on items is hidden it will have to be obtained via in-game testing when using spirit power. For example, equipping Tesla Bullets alongside Boundless Spirit (which adds 76 total spirit power) increases the spirit damage of Tesla Bullets from 30 to 40. Following the lookup formula:

$𝑆 𝑝 𝑖 𝑟 𝑖 𝑡 𝑃 𝑜 𝑤 𝑒 𝑟 𝐶 𝑜 𝑒 𝑓 𝑓 𝑖 𝑐 𝑖 𝑒 𝑛 𝑡 = (𝑆 𝑝 𝑖 𝑟 𝑖 𝑡 𝐷 𝑎 𝑚 𝑎 𝑔 𝑒 - 𝐵 𝑎 𝑠 𝑒 𝐷 𝑎 𝑚 𝑎 𝑔 𝑒) / 𝑆 𝑝 𝑖 𝑟 𝑖 𝑡 𝑃 𝑜 𝑤 𝑒 𝑟$

It is possible to calculate the coefficient as:

$𝑆 𝑝 𝑖 𝑟 𝑖 𝑡 𝑃 𝑜 𝑤 𝑒 𝑟 𝐶 𝑜 𝑒 𝑓 𝑓 𝑖 𝑐 𝑖 𝑒 𝑛 𝑡 = (40 - 30) / 76 = 0.1315 \dots$

However, rounding errors make this value slightly inaccurate when applying it with other spirit power values. Until the spirit scaling is shown in the tooltip for items in a similar fashion to abilities, this approximation technique is the only way to gauge the effectiveness of scaling spirit power for items.

All spirit items implicitly provide Spirit Power based on tier, represented as "Shop Bonuses" in the ingame stats calculation. Tier 1 items provide +4 Spirit Power, Tier 2 items provide +8, Tier 3 items provide +12, and Tier 4 items provide +16. The following items explicitly grant increased Spirit Power:

Map spawns

Golden Statues can provide a permanent increase: +2 Spirit Power before 10 minutes, +3 Spirit Power before 25 minutes, and +5 Spirit Power after 25 minutes.
Power up runes can provide a temporary Casting buff that provides +25 Spirit Power for 160 seconds.

Spirit scaling by hero

Many ability attributes scale with Spirit Power. Certain heroes also have Spirit scaling on their stats (such as Haze, whose ammo capacity increases by x0.5 for each point of Spirit Power). This table compiles each hero's stat and ability scaling coefficients as determined by sandbox testing.
