This is more of a feature request/suggestion than anything. Mimic's are fantastic though if you have any mod that gives you information about what you're looking at, it immediately gives the mimic away. (Neat has a blacklist for entities but its clientside so its easily gotten around)

I can think of two solutions:

• Mimic's could be renamed to be simply Chest, as to fool usage of HWYLA, One Probe etc.
• Mimic's start as blocks identical to actual chests rather than actual entities. Once opened, they are replaced with an actual mimic. This would both avoid them having any kind of health until opened, and would also allow players to collide with/stand on the mimic like a normal chest.

would be perfect
I am aware of the age of this suggestion and posted in order to give it more importance and hoping this could be accomplished
also might be that HWYLA, JADE, etc might be more of a help here setting this up

@Snownee
sorry for pinging you here - no idea how to ping JADE itself
whats your thought on that suggestion and could JADE implement something like that?

• Mimic's start as blocks identical to actual chests rather than actual entities. Once opened, they are replaced with an actual mimic. This would both avoid them having any kind of health until opened, and would also allow players to collide with/stand on the mimic like a normal chest.

I was initially thinking Mimics could be given their own collisions similar to Shulkers, but I think your idea is better. There wouldn't be any need to override any behavior of the vanilla chest if a separate "Mimic Chest" block is implemented. A newly spawned Mimic consuming a vanilla chest would only need to replace it with the fake block version, temporarily removing the mob itself, which would then turn back into the Mimic mob once the fake chest is opened by a player.

I've also taken a quick look at the JADE wiki, and it seems that there may already be a way for other mods/plugins to override info displayed by JADE. This example shows a block entry being changed from one to another, although I don't know if it's equally possible to override the mod name displayed underneath the block entry, as I imagine it will also easily break this mod's disguise.
