Auditor/Employer like origin for Arena, concept ideas

[DarkEstella]

I do believe that having an Auditor/Employer like Origin for Arena would be quite cool.

So if any of you got concept ideas, do share.

Here's mine, nothing too big:
Abilities/Strengths -
*Can equip any weapon at anytime, even in the middle of a fight ( Reference to how Auditor was able to summon any weapon in the series )
*Low chance to ignore damage ( Due to the smoky body )
*Teleport ?

Weaknesses:
*Unarmed less damage ( Auditor seems to not be too good in fist fighting )
*Limited to 2 corpus
