The world is your canvas and the ground itself … The Jellyfish Statue is a functional statue found underground. Some statue-spawned enemies will not drop items at all if they are killed by traps. However, there are limits to statue farming: Statue-spawned enemies do not drop coins and many have reduced drops. Nothing is impossible in this action-packed adventure game. Yeah, Heart statues are found rarely. are there any other really great statues i should know about?

But when you find one, it is a great help for boss fights, events like the Blood Moon and so on. An already-rare drop with reduced chances can require considerable amount of time to farm.
When wired to a trigger and activated, the statue will spawn Blue Jellyfish. Afterwards, three more jellyfish can be spawned. In 1.3.1 update a lot of new statues were added that can give different items.

usually the item drop rate is divided by 25 but the grolem statue still has a full drop rate, and it drops nightvision helmet which sells for 2G. Multiple statues in a lava pit can speed things up. Three jellyfish can be spawned before there is a short cooldown. r/Terraria: Dig, fight, explore, build!
