Does the Sorcerer's Innate Sorcery feature cause the attack made with the True Strike cantrip to have advantage?
Note: the question isn't whether you would allow it at your table, but whether you think it's allowed by the rules.
Innate Sorcery
An event in your past left an indelible mark on you, infusing you with simmering magic. As a Bonus Action, you can unleash that magic for 1 minute, during which you gain the following benefits:
- The spell save DC of your Sorcerer spells increases by 1.
- You have Advantage on the attack rolls of Sorcerer spells you cast.
True Strike
Casting Time: Action
Range: Self
Components: S, M (a weapon with which you have proficiency and that is worth 1+ CP)
Duration: Instantaneous
Guided by a flash of magical insight, you make one attack with the weapon used in the spell's casting. The attack uses your spellcasting ability for the attack and damage rolls instead of using your Strength or Dexterity. If the attacks deals damage, it can be Radiant damage or the weapon's normal damage type (your choice).
