Miner's Familiar

Blessing

When you cast the find familiar spell, you can have your familiar appear as an elemental.

Additionally, you can provide additional material components when you cast the spell to grant special traits to your familiar until you cast the spell again. These additional components are not consumed. You still decide the familiar's form and statistics, but it appears to be made of the same material as the provided component. Alternatively, it can appear to wear the material like armor. For example, if you provide iron and summon a crab, it might appear as a hermit crab living inside a hollow chunk of iron ore.

This table can maybe be trimmed, especially if split into armor and type effects
