Arcanus Oculum

A steel eyeball covered in magical glyphs with the iris a circular magic seal glowing a deep yellow orange. to attune and use this item is to replace one of your eyes with it, and the attuning process is a painful one. the user takes 2d10 + 25 psychic damage over a one-hour ritual that cannot be reduced in any way as the steel eye slowly assimilates the eye to be replaced.

once attuned, the steel eye grants several abilities.

• grants darkvision up to 80 feet and be able to see into magical darkness within that range. If you already have dark vision, this replaces that ability unless your darkvision sees further than 80 feet.
• allows you to cast the spell detect magic at will without spending a spell slot or use any components.
• from a pool of 9 charges that refill at dawn, can as a reaction have advantage on all saving throws against magic that you can see and that has you as an intended target of the spell until your next turn.
  • from that same pool of charges can cast the spells "see invisibility", "identify", "arcane eye", "locate creature", "hold person", "hold monster", "scrying", "eyebite".
