This deals minor damage if a target comes near the teleportation area.
Maintain your distance or dash away from the projectiles and poison clouds.
Hydra Leader gathers a large poison orb before launching three venom bolts that leave behind poison puddles, which then split into additional puddles and deal moderate damage.
