Mimics can be very scary.

Bonus Konsi?

Play Shattered Pixel Dungeon. You can get special mimics that can disguise as literally everything. A door, strength potion, the way to the next level, basically anything that looks useful. And of course they only appear as soon as you've forgotten to check for them.

That's why you need post it on your stuff.

Teleportation mimic will teleport you. To its stomach.

Breastplate mimic just wants to sink its mouth on your breasts.

Saddle mimic wants to lick your lowers parts.

No comment on outhouse mimic. We don't talk about it.

Not my menstrual cup!

I've always been a fan of mimics being ladders or bridges.

Cover your phb in spray adhesive and leave it sitting on the table. As soon as someone touches it, shout "ROLL INITIATIVE!"

Actually, apply this to other random objects at the game table. A bag of chips, 1 can of soda in the fridge, every 3rd pencil, whatever.

Mimic city; every building is a mimic, but they're smart enough to eat the local population when they're alone or in small groups. Every time people keep going missing, and the players will assume it must be some random wandering monster; they'd never think it's literally the buildings and each room can start eating really fast. There'd be no pattern either, every building is alive and people go missing literally everywhere. Perhaps a clue can be a house that has no more people living in it and it starts to starve to death and starts freaking out, even endangering the other mimics' secret.

This is similar to the premise of Prey.

I've often thought it'd be fun to let a party have a tame mimic as a pet. Not helpful in battle unfortunately, unless one of your opponents decides to take a looting break.

And then we have Starfinder where a mimic can disguise itself as an entire planet!

The player handbook isn’t a problem, no one reads that thing.

Abomination Vaults has a mimic encounter where one is pretending to be a door and the other is pretending to be a weapon rack with a nice axe on it. Gets them either way.

You might also want to look into Rotgrind's Mimouthouse. It's exactly what it sounds like.

having the table you are irl playing at turning into a mimic and having to roll stats for your irl person in order to continue sounds really fun

I think in the early editions they said that mimics were only really effective at imitating wood and stone. I agree that mimic chests are done to death but "anything could be a mimic" would get old fast I fear. Limiting them to only some materials but then getting creative within those limits would keep it interesting without it feeling like a cheap jumpscare.

I wanna share this in the group chat, but I don't wanna give the GM any ideas xD

One D&D podcast I listen to had one be a house in Sigil. After they had dealt with the plot to use it for magic or something some of the party ended up feeding it animals much to the chagrin of the rest of the party but did save some other creatures living in the area from getting eaten.

What about the party being mimics but don't tell them that.

My sister and I were diving deep into the lore and rules for mimics and the most terrifying thing they could be, is either an entire planet or a humanoid. They might even be able to be a planet-sized humanoid. Or even a human-sized planetoid 😱

It's always more fun when mimics team up. A couple of goblins bother the party at night, just enough to give them chase, then when they return, hop into their sleeping bag and boom, mimic.

outhouse oof.

Can't remember if it was ds2 or ds3 but one of em had bonfire mimics concept arts.

The PHB mimic is starving

Spyglass: thoomp

The rug under the chest is my favourite. I'm gonna give my players more trust issues, thank you

A shirt or your gear.

Anal prayer beads because monks is kinky.
