Strategies
s can easily kill careless players. To avoid its attacks, try to attack it when it's against a wall or on an elevated platform (e.g., the mushrooms). Make sure to avoid its webs as much as possible.

The Vaccine Talisman does not grant immunity to the venom inflicted by s, so players with it will still be reduced to 1% periodically in the same way that Arachne's venom works.
