How to play

Early game · first 8 minutes
Poke from an angle, build Screwjab Dagger pressure on one target, and use Slither to avoid the return trade. Commit Petrifying Bola when locking that target creates a real kill window. Keep the second enemy in mind before you stay for the poison damage.
Mid game
Use Petrifying Bola to create the commitment, follow with Screwjab Dagger and Lethal Venom on the locked target, then use Slither to survive the return pressure. Treat the slide barrier upgrade as a commit window, not permission to stay forever.
Late game
Petrify an important damage dealer when your team can follow, apply Lethal Venom while the target is controlled, then use Slither to reset. If Slither is unavailable, wait outside the center of the fight until you have a safe exit.
