Notes

Shooting an enemy hero deals 55 damage and applies 1 stack of Siphon* for 20 seconds, refreshing on subsequent applications, and stacking infinitely. Afflicting an enemy with Siphon places the effect on a per-user cooldown of 0.8 seconds. Each stack of Siphon lowers the maximum health of affected heroes by 55.

Each stack of Siphon will always remove 55 max HP from afflicted targets, but the flat damage dealt may interact with certain passives (tested at half HP to visualize damage dealt independently from max HP loss).

• The 55 damage dealt by Siphon Bullets cannot be increased or decreased by Bullet Resist, Spirit Resist, or damage amplification (Pocket's 1 or Escalating Exposure).
• Shiv's Bloodletting passive will reduce the flat damage dealt by Siphon Bullets, but Shiv will still lose 55 max HP per stack
• The 55 damage dealt by Siphon Bullets will still trigger Abram's regeneration passive
• The damage dealt by Siphon Bullets does not proc item effects.
• Siphon Bullets does not trigger if the initial bullet deals 0 damage
• Siphon Bullets can be applied by Ricochet, but the per-user cooldown of 0.8 seconds still applies.

Upon inflicting Siphon on an enemy, the user gains one stack of Siphoning for 20 seconds and then heals 55 health. Each stack of Siphoning increases maximum health by 55. When an enemy with Siphon has their stacks refreshed, the Siphoning stacks gained from that enemy also have their duration refreshed. If Siphoning stacks have been gained from multiple enemies, refreshing the duration of Siphon on an enemy will only refresh the duration of Siphoning stacks gained from that target.

• If an enemy with Siphon has their stacks expire, the enemy is healed for the same amount of max HP restored
• An enemy can use Debuff Remover to remove stacks of Siphon; this does not remove Siphoning stacks from the owner of Siphon Bullets

When an enemy affected by Siphon dies, the item holder heals 55 health and gains one invisible stack of Siphoner. Additionally, the killed enemy gains one invisible and uncleansable stack of Siphoned. Upon death, the two most recently applied Siphoned stacks are removed from their targets and the item holder will lose two stacks of Siphoner.

• Selling Siphon Bullets does not remove Siphoned from affected enemies.

Health gained from Siphoning is visible on the user's healthbar to allies and enemies.
