The Beenade is an explosive that creates a small explosion and releases a swarm of bees and deals damage only to players and monsters without destroying any terrain tiles.
Like Grenades, this will explode on impact with a monster or projectile. Unlike grenades, however, you cannot kill yourself with beenades.
The bees released from Beenade are the same bees shot by Bee Gun, thus they can be affected by magic buffs and trigger Spectre Armor's set bonus. They also immediately despawn upon contact with any liquid.
