Of course, the description of the Apparatus already specifies its AC and hit points. As for what happens when those hit points are depleted: Related items [ ] This section is incomplete. Please complete this section and remove this {{ secstub}} notice.

Adamantine Chain Shirt (50 gp (base cost) + (300 (3rd level spell) * 10 (permanency))) * 1.5 (rarity) = 4,575 gp

Ammunition, +3 (2,520 gp (lv6 spell) * 1.1) * 3 (rarity) = 8,316 gp / 2 = 4,158 gp Amulet of Health The apparatus of Kwalish returned in the Advanced Dungeons & Dragons 2nd edition Dungeon Master Guide (2e) (1989). The Advanced Dungeons & Dragons 1st edition incarnation was updated for the Encyclopedia Magica Volume One (1994). The Apparatus's description says that it is a large object. As explained in the DMG (and basic rules) section on objects: Arrow-Catch Shield 900 gp (+1 AC) * 3 (cumulative bonus) + 90 gp (lv1 spell) * 10 (permanent) * 2 (rarity) = 7,200 gp Arrow of Slaying

When it makes sense to do so, the DM can assign statistics to an object to determine how hard it is to destroy: Amulet of Proof Against Detection and Location 300 gp*6 (4+1*2)*1.5 = 2,700 gp Amulet of the Planes Amulet of Health 630gp (lv5 spell) * 10 [+1+2+3+4 (cumulative modifiers)] * 2 (rarity) = 12,600 gp Amulet of Proof Against Detection and Location This is an oddball item, and is going to be fairly cheap EXCEPT for the fact if you get enough of them in one area… it can cause some problems with economics. A common pitcher of wine is 2 sp, so we’ll say that that is roughly the same volume as a bottle of fine wine. There are five bottles of wine per gallon, so that is only 1 gp worth of wine in the alchemy jug. Even if we say the wine is good, that is only 50 gp worth of wine in the alchemy jug per day. We could multiply that amount by permanency and rarity, but that only gets us to 750 gp - which… maybe that is enough? The apparatus of Kwalish was originally created by its namesake to explore the ocean depths and establish relations with sentient underwater races. [4]The apparatus contained controls that allowed for a number of maneuvers. It was first and foremost a vehicle that could walk on the ground as effectively as on the water and underwater. It was capable of safely submerging up to a depth of 900 feet (270 meters) and its airtight inner compartment could store enough breathable air to last for up to ten hours (or five, if occupied by two creatures).

The device has the following characteristics: hp 200; hardness 15; Spd 20 ft., swim 20 ft.; AC 20 (—1 size, +11 natural); Atk +12 melee (2d8, 2 pincers).

When not in operation, the apparatus resembled a large iron barrel. It had a concealed latch that allowed access inside, where the control systems were located. When deployed and in operation, an apparatus of Kwalish resembled a giant lobster. It could fit up to two people inside. Its controls consisted of a set of ten levers, each responsible for a different aspect of the vehicle's operation. [3] Powers [ ]To be used as a vehicle, the apparatus requires one pilot. While the apparatus's hatch is closed, the compartment is airtight and watertight. The compartment holds enough air for 10 hours of breathing, divided by the number of breathing creatures inside.

Suggested uses for the Apparatus were described in the web article Tactics and Tips: The Forgotten Magic Cache (Part 3). [7] D&D 4th edition [ ] To be used as a vehicle, the apparatus requires one pilot. While the apparatus’s hatch is closed, the compartment is airtight and watertight. The compartment holds enough air for 10 hours of breathing, divided by the number of breathing creatures inside. Relic: A gnome has double the amount of air when a passenger, or it attuned does not run out of air. Leather, Armor of Resistance 90 gp (lv1 spell) * 10 (permanent) * 2 (rarity) + 10 gp (armor cost) = 1,810 gpArmor of Invulnerability 1260 gp (lv5 spell) * 10 (permanency) + 3240 gp (lv7 spell) * 4 (one-use/day) * 5 (rarity) = 127,800 gp Armor of Resistance It’s kind of a weird item. It has next to no impact on mechanics, but feels weird to say an infinite supply of mayonnaise is south of 1,000 gp. I’ve seen some other magic item guides price it as high as 6,000 gp - so some people go really far with its price (pry to stop adventurers from leaving a life of adventuring and just mass producing vinegar). The apparatus of Kwalish does not exist in Ansalon.
