Zuzeshi's basic attacks deal 3/4/5% of his bonus health and mana as bonus magic damage on-attack (scaling with R), increasing in damage as his health and mana decrease (0% at 100%, 100% at 20%).

Each new application of the Spirit of the Viper increases Zuzeshi’s mana regeneration rate by 10/14/18%, increased based on his missing mana (0% at 100% mana, 100% at 20% mana). The Spirit of the Viper lasts 4 seconds.

He moves 5% + (5% per 100 bonus health, 5% per 100 bonus mana) faster towards targets that have recently been damaged by the Spirit of the Viper.

Any unit that dies to the Viper’s venom is eaten by Zuzeshi, healing him for 1 -> 3% of their maximum health and restoring 1 -> 3% of his maximum mana.

Zuzeshi’s next basic attack deals bonus damage equal to 7/11/15% of Zuzeshi’s maximum health and mana as magic damage in an area and applies the Spirit of the Viper to all targets hit. Usage of any ability on a valid target lowers this CD by 0.5 seconds per target.

​If a target is already affected by the Spirit of the Viper, Boaslam will refresh the Spirit of the Viper and knock the target up and slightly towards Zuzeshi.

Zuzeshi gains camouflage for the next 8/9/10/11/indefinite seconds. While in this form, Zuzeshi gains 10/14/18/22/26% movement speed.

Zuzeshi’s next basic attack will cause him to dash to the target up to 400 units and rear up with a cobra’s hood, fearing the target and all nearby targets for 1/1.1/1.2/1.3/1.4 seconds. This basic attack will deal damage from the Spirit of the Viper twice to the initial target and once to all targets within 400 units.

Zuzeshi’s next basic attack applies a venom that lasts 4 seconds, refreshing every time Zuzeshi attacks the target. The venom deals 1% of Zuzeshi's maximum health and mana as true damage to the target per second. If Zuzeshi kills a target is affected by the venom, Zuzeshi will eat them, permanently granting him 1% of their maximum health and mana. If they don't have mana, Zuzeshi will gain an amount of mana equal to the health he gained.

This poison deals the Spirit of the Viper’s damage every second, healing Zuzeshi for 33/66/99% of the post-mitigated damage (scaling with R)

Important: Zuzeshi gains no health or mana from leveling up. He must kill things with the Asp’s venom to gain these stats outside items.

Zuzeshi launches in the target direction, latching parasitically onto the first enemy Champion hit. If he hits an enemy Champion, he becomes untargetably attached to them and swaps his kit out with the following abilities, for up to 4 seconds.

They can continue to move and use basic abilities, but they are locked out of their ultimate. Stasis abilities will also put Zuzeshi into stasis, pausing his parasitic timer.

Puppeteer: If Zuzeshi has more health than his prey, they obey his movement commands instead of their player’s movement commands. They are still free to basic attack and use abilities.

​

Serpent’s Embrace can only be ended by crowd control from targets with more maximum health than Zuzeshi, or Zuzeshi himself.

​

While Zuzeshi is attached to a target, they become unable to use their own ult, with Constriction instead taking the place of their ult, showing them the timer of how much longer they'll have Zuzeshi attached to them.

Zuzeshi forces his prey to attack their nearest ally, resetting their basic attack timer and dealing the Spirit of the Viper’s damage as true damage.

Zuzeshi’s tail rattles wildly, fearing all targets near his prey and heavily slowing them for the duration. This deals magic damage equal to 10/12/14% of his bonus health to all targets within 450 units of Zuzeshi.

Zuzeshi bites his prey, injecting them with a venom that forces them to berserker on their allies for the next 2/3/4 seconds. Zuzeshi then spits venom each time his prey basic attacks, dealing the Spirit of the Viper’s damage, but dealing true damage instead. If his prey has Guinsoo’s Rageblade, the Spirit of the Viper will be affected.

Zuzeshi attempts to swallow his prey over the course of the Serpent’s Embrace, dealing 8/10/12% +  (8/10/12% bonus health) of his maximum health to them as true damage over the duration of the ability. If he swallows them, he gains maximum health and becomes larger, ending Serpent’s Embrace and healing for twice the damage he dealt.
He gains 3% of their maximum health and mana as bonus health upon successfully eating them.

The R will show the duration of the ability as a circular timer. Activating it will end the Embrace.
