Shape and Placement
- Must create armor-like features
- Cannot alter existing keratin, but may be layered over top of it
- Shapes must be semi-realistic (it should still look like a realistic dinosaur feature, not overly fantasy)
- Armor can appear on any part of the body, but it may not cover eyes and mouths
- Can be separate areas of the body- does not need to all be connected
- Not allowed to mimic other mutations (particularly Thorny)
Color & Style
- Lines must be drawn to look similar to the lines of the import for style consistency
- Optional keratin area - it can be treated as keratin plates, or may be colored like normal skin, as long as its consistent across the entire design.
- Can be affected by color modifiers following regular keratin rules
Interactions
- May be combined with other mutation features, such as Thorny.
- May layer on top of or under other mutations as long as its consistent across the design.
- If presenting as "skin", it can cover feathers on a feathered dino to create false bald patches.
- If presenting as "keratin", you may cover up feathered features such as crests, and/or draw some feathering over the edges of the plates.

Exoskeleton should not form prominent points nor spikes. They can be slightly spiked if they are overlapping to where the point does not prominently stick out. However, if the layering of the plate causes the spike to appear too large, it will not pass.
Range
- Minimum requirement- at least one armored area/"plate" of armor
- Maximum allowance- may cover up to 50% of the body
- This mutation may appear anywhere on the body, except for covering the eyes and mouth!
