Valheim Defenders

One day, waves of enemies will come to attack your base. Start building these new elemental versions of the ballista to defend it.

Valheim Defenders adds elemental variations of the ballista. There are mini and normal size and a new micro size ballista. The new ballistae do elemental damage: Ice, Fire, Poison and Lightning. They each do some elemental damage of their type and adds the corresponding status effect to the target. ex: Ice Ballista does frost damage and adds the frost slowing effect.

*** Ballistae can be found in the 'Defenders' tab in the hammer menu. ***
