The chill touch cantrip came coming… but to no effect. The spider seemed to have immunity to necrotic damage. Although, it did distract it long enough for Hermes to get to the door on the opposite side from the spider. The door was unlocked and he could pull it open. Then as the door opened, the dome detached itself from its legs and flew to the middle of the room.
Grabbing the lock picks, he attempted to pick the door. Except, what he noticed was that the door was unlocked the whole time.
