Trick Weapon

As a Bonus Action, you can switch between the Transformed and Untransformed states of this weapon. In its Untransformed state, the gazer is a Glaive. In its Transformed state, the gazer is a Glaive that can be used as a Spellcasting Focus. To transform this weapon, you must feed it your blood: each time you shift this weapon into its Transformed state, or start your turn with the weapon in its Transformed state, you take 1d4 Necrotic damage, which can't be reduced or prevented in any way. This damage can't break your Concentration.

Transformed

While the weapon is in its Transformed state, it grants you a +2 bonus to spell attack rolls, increases your spell save DC by 1, and gives you Truesight with a range of 30 feet.
