So this is the product of a one-off joke at last week's game, I just couldn't get the idea out of my head.
You are a Mimic Tamer! Handler of the strange and aberrant, friend of the shapechangers and dopplegangers. You spend a large portion of your professional time spelunking through crypts and caverns in search of that famous ambush predator, the Mimic. While most folks revile such predatory and alien creatures, you know that they are more intelligent than they get credit for, and are even kinda cute.
Mimic Tamer
The tamer and mimic act as one character, and share an HP pool.
For every template of Mimic Tamer you possess, gain a +1 on reaction rolls versus mutants, horrors, and aberrations. Also, +1 to notice disguised mimics and other shapeshifters.
Starting skill: 1. Game trapper 2. Impressionist 3. Whisperer
Equipment: Bludgeon, Leash, Whistle, Treats
A
Small & Obedient Mimic - through careful and patient training you have tamed a mimic the size of a small dog. It can shapechange into any mundane object that could fit in a backpack, but retains the density of flesh. It can also perform single word tasks such as "fetch, stay, sick'em, protecc". It is cowardly unless the tamer is within eyesight, and cannot make attacks on its own, only in tandem with the tamer or an ally (see "ankle biter")
Ankle Biter - When you or an ally make a melee attack while adjacent to the Mimic, roll an additional d4 along with your damage dice. If the result on this die is greater than your own damage result, use it instead. The mimic can only provide this bonus once per turn.
B
"Hold this for me" - Your mimic is now the size of a large dog, and has mastered turning into a chest, it now has 6 item slots! It stores things in it's belly, any retrieved item is covered in a thin mucus.
Ankle Biter - Increase the die to a d6.
C
"Ride like the wind!" - Your mimic is now the size of a couch, and can be ridden by one adult, or two children.
Ankle Biter - Increase the die to a d8
D
"They grow up so fast" - Your mimic is now fully grown! It gains an additional 4 item slots and is intelligent enough to understand full sentences and follow instructions that a 10 year old could follow.
Ankle Biter - Increase the die to a d10
