Abilities
Motion Sense 60 feet — A vaultbreaker ooze can sense nearby motion through vibration and air movement.
Treasure Sense (Imprecise) 30 feet — The vaultbreaker ooze's metallic plasm alerts it to the presence of metals with the precious trait (including gold and platinum) within 30 feet.
Metallify (manipulate, polymorph) —
Engulf — DC 23 Reflex, 2d8+9 acid damage, Escape, Rupture 14 (19 when using Metallify)
The monster Strides up to double its Speed and can move through the spaces of any creatures in its path. Any creature of the monster's size or smaller whose space the monster moves through can attempt a Reflex save with the listed DC to avoid being engulfed. A creature unable to act automatically critically fails this save. If a creature succeeds at its save, it can choose to be either pushed aside (out of the monster's path) or pushed in front of the monster to the end of the monster's movement. The monster can attempt to Engulf the same creature only once in a single use of Engulf. The monster can contain as many creatures as can fit in its space.
A creature that fails its save is pulled into the monster's body. It is Grabbed, is Slowed 1, and has to hold its breath or start suffocating. The creature takes the listed amount of damage when first engulfed and at the end of each of its turns while it's engulfed. An engulfed creature can get free by Escaping against the listed escape DC. An engulfed creature can attack the monster engulfing it, but only with unarmed attacks or with weapons of light Bulk or less. The engulfing creature is Off-Guard against the attack. If the monster takes piercing or slashing damage equaling or exceeding the listed Rupture value from a single attack or spell, the engulfed creature cuts itself free.
Effect: Engulf and Swallow Whole
A creature that gets free by either method can immediately breathe and exits the swallowing monster's space.
If the monster dies, all creatures it has engulfed are automatically released as the monster's form loses cohesion.

Form Tool (manipulate, polymorph) — The vaultbreaker ooze instinctually shapes its pseudopod into a key, lockpick, or tool required to bypass a locking mechanism; it uses this pseudopod as thieves' tools to Pick A Lock or Disable Device.
WORKS WELL WITH
SniperLAND / VERTICALA ranged attacker keeps dealing damage from outside Engulf's reach while this ooze ties down whichever creature it traps.
FlankerLANDA mobile striker can reposition around the ooze's slow advance and exploit Off-Guard on whoever is busy escaping the Engulf.
SnareLAND / VERTICALA second controller locking down the rest of the party lets the ooze focus its Engulf on a single isolated target without interference.
PUNISHES
✖ precision reliance✖ critical-hit reliance✖ isolated positioning
Avoid pairing with another high-HP damage sponge, since a party facing two such threats will simply disengage rather than trade blows with either.
