Privacy Bubble

The Privacy Bubble first appears in Book 2 as a simple translucent head-enclosing sphere that muffles external noise for private conversation, activated by a finger-circle gesture and initially tied to a basic club spell. Across subsequent books, it evolves from a niche utility item into a versatile tactical tool, gaining enhanced soundproofing, visual distortion, and integration with Carl's expanding spell repertoire. Its role shifts from mere conversational privacy to strategic battlefield advantage, reflecting Carl's growing need for both discretion and combat flexibility within the dungeon's increasingly complex social and tactical landscape.
