Arcane Surge is a Tier 2 Spirit Item that grants Stamina and Stamina Recovery. Its passive effect causes a hero's next Dash Jump to grant extra Ability Range, Duration, and Spirit Power to the next ability used.

Arcane Surge is a Tier 2 Spirit Item that can be purchased from the Shop for 1,600. Its component, Extra Stamina, makes up 800 of the cost.

Notes

Items and passive abilities cannot benefit from the conditional buff - they will not gain additional spirit power, duration, or range.
The buff which provides the player with the conditional ability range, ability duration, and spirit power lasts for 7 seconds.
The first ability cast after gaining the buff will consume the buff.
The conditional ability range and ability duration are snapshot on ability use.
The conditional spirit power is tied to the 7 second timer of the conditional buff. The +15 spirit power will only be available for 7 seconds after the player initially gains the conditional buff.

Examples:

6 seconds after gaining the conditional buff, Vindicta uses Assassinate.
- This consumes the buff, and applies +15 spirit power to Assassinate's damage.
6 seconds after gaining the conditional buff, Seven uses Lightning Ball.
- The buff is consumed.
- The Lightning Ball gains +15% ability duration and +15% ability range.
- The Lightning Ball gains +15 spirit power for 1 second only. For the rest of its duration, it does not benefit from +15 spirit power.
6 seconds after gaining the conditional buff, Seven uses Power Surge.
- The buff is consumed.
- Power Surge gains +15% ability duration and +15% ability range.
- Power Surge's damage benefits from +15 spirit power for 1 second only. For the rest of its duration, the damage does not benefit from +15 spirit power.
- Power Surge's total duration scales natively with spirit power at time of cast. The additional duration due to the +15 spirit power is snapshot on cast, and is not lost when the 7s conditional buff is consumed.
