Edith nimbly jumps through the window so the 1 (ONE) STRANGE CIRCULAR KEY isn't used unnecessarily.

Edith says she has a SNIPER RIFLE that has an INFINITE MAGAZINE that spews out an infinite amount of bullets but at this point with the INSATIABLE AMMO SATCHEL its kind of redundant.

Edith's CLASS OPERANDI is INTREPID ASSASSIN. She can use and purchase MODUS OPERANDI SKILLS relating to stealth, killing and ranged shooting.

Her SNIPER RIFLE is the only ranged weapon she can use, however it can be heavily upgraded similar to Timmard's ROLLING CHAIR. You'll have to check the shop to see the upgrades or hope some show up in the dungeon.
