Silent Weaver

You have mastered the art of suppressing the telltale signs of your arcane power, turning your magic into a ghostly presence that leaves no trace in the air or the ears of your enemies. Whether through extreme mental discipline or a unique manipulation of the local atmosphere, your spells lack the usual thunderous cracks and luminous flares.

You gain the following benefits:

• Muffled Resonance: When you cast a spell that deals damage, the sonic component of the spell is suppressed. The spell makes no audible sound upon impact (such as a thunderclap or explosion), and the magical manifestation is visually muted, making it difficult to pinpoint the exact moment of casting in dim light.
• Arcane Stillness: You can attempt to cast a spell without using its verbal or somatic components. When you do so, you must make a Constitution saving throw (DC = 10 + the spell's level). On a success, the spell is cast as if using the Subtle Spell like effect, leaving no trace of your casting. On a failure, the spell is cast normally, but the sudden leak of mana creates a brief, audible pop or a flash of light, potentially alerting nearby creatures to your position.
• Quiet Presence: You gain advantage on Stealth checks made while you are actively concentrating on a spell, as you instinctively synchronize your breathing and movements with the flow of your mana.
