All Seeing Eye

All Seeing Eye is activated using "focus points" as a bonus action. The number of points you have is equal to your level + wisdom modifier. While All Seeing Eye is active, you gain the following benefits:

• You can see up to 500ft away is if you were close to the object being viewed. In this range you can detect the presence of magic, but not the type of magic.
• You can see up to 10ft. through solid materials, excluding lead and magical materials.
• You gain 60ft. of truesight.
• You gain a 1d4 bonus to dexterity saving throws while this ability is active.
• You can add double your wisdom modifier to perception and insight checks.
• Anyone who moves after you in the initiative order rolls their first attack against you with a penalty of -1d4.
• You make saving throws against visual hallucinations and illusions with advantage.

(This feat is not intended to be available under normal circumstances, such as via an ASI or racial feature. If used in that way, it is incredibly unbalanced and will probably ruin the game.)
