Stealthy Spellcaster

General Feat (Prerequisite: Level 4+, Dexterity 13+)

You gain the following benefits.

Ability Score Increase. Increase your Dexterity score by 1, to a maximum of 20.

Concealed Casting. As part of a Magic action while casting a spell, you can make a Dexterity (Sleight of Hand) check to hide your use of Verbal, Somatic, and non-obvious Material components; typically, creatures with a passive Perception less than your roll cannot tell that you cast a spell, unless the spell effect makes it obvious. Particularly distracting or calm circumstances may result in making the Sleight of Hand check with Advantage or Disadvantage. If a creature is actively observing you while you cast a spell, that creature can choose to make an active Perception check instead of relying on passive Perception.
