Lightseer's Gaze

Wondrous item, artifact (requires attunement by a monk)

This flourished mask obscures your eyes and magically stays in place while worn. It once belonged to a wise spiritual leader whose name has been lost to time, but was said to have eschewed personal belongings. While wearing the mask and attuned to it, you gain the following benefits, with all saving throws being equal to your own save DC:

• You have blindsight out to a range of 120 feet, and truesight out to a range of 60 feet. You are blind beyond this radius. Despite being blind, you can still see the moon, stars, and sun when they're in the sky above you.
• Your Wisdom score increases by 2.
• You have advantage on Wisdom (Insight) checks.
• You can spend 3 ki points as an action to cast the Spirit Guardians spell at 10th level.
• You can use an action to spend 2 ki points to cast the Calm Emotions spell. Alternatively, if you speak to a hostile creature for 1 minute, it must succeed on a Charisma saving throw or become indifferent about creatures of your choice that it is hostile toward, as if affected by the calm emotions spell (no concentration required). If a creature succeeds on the saving throw in this way, it's immune to the effects of this property for 24 hours.
• As a reaction, you can spend 3 ki points to cast Counterspell. You may also spend any number of additional ki points, for each spent this way Counterspell is cast one level higher.
• Whenever you stun or paralyze a creature, they are also blinded.
• You have resistance to radiant damage.
• You can't be charmed or frightened.
• You gain a +2 bonus to your saving throws.

Curse. This item is cursed, and attuning to it extends that curse to you. You can't remove the mask while cursed in this way. You remain cursed until it's ended by a wish spell or similar magic. When you become cursed, your name remains known to only you but becomes lost to the rest of the universe, at the GM's discretion. You must choose a new name. This new name replaces every instance of your lost name throughout history, and becomes the only known name for you among all creatures who once knew your lost name. While cursed, you take 5d10 psychic damage whenever you attempt to speak, write, or otherwise share or communicate your lost name. Regardless of how you attempt to share the lost name, it always comes across as your new one.

"The Material is just a side of a coin. A single dimension. What we have here isn't really permanent, nor is it truly only ours. The wind, sea, earth…all only small parts of larger pieces of a whole. I see more. I see the whole. I see the aether, and my spirit will guide me through it."
