Yes Familiar can be pretty much any kind of creature, magical, humanoid, or not. Which most familiars have the power to transform into a humanoid form to do tasks for their master such as passing out fliers and etc. pretty much small things they can't be bothered with.

Nerminator what exactly do you mean by 'magical staff that can heal and protect people' you got to remember you got high magic so you can't have to good of a Sacred gear so I need to know how strong it's healing/protecting capabilities are.

you can erase the 'notes' from your cs I just put them there so you wouldn't miss or overlook needed information lol.
