Random Magic Wondrous Item

Apparatus of Kwalish

This item appears to be a large, sealed iron barrel, but it has a secret catch (Search DC 20 to locate) that opens a hatch in one end. Anyone who crawls inside finds ten (unlabeled) levers:

The device has the following characteristics:

• Speed: Forward 10 ft., backward 20 ft.
• AC: 20 (-1 size, 11.natural)
• Hit Points: 200
• Attacks: 2 pincers, +12 melee
• Damage: 2d8 each
• Special Qualities: Hardness 15

Operating a lever is a full-round action, and no lever may be operated more than once per round. However, since two Medium-size characters can fit inside, the apparatus can move and attack in the same round. The device can function in water up to 900 feet deep. It holds enough air for a crew of two to survive 1d4+1 hours (twice as long for a single occupant). When activated, the apparatus looks something like a giant lobster.
