Collapse (Ex)

Once a conch tree swallows a creature whole, it can collapse into a smaller hard shell to protect itself while it digests its prey.

The tree curls around its prey, reinforcing its own outer flesh and changing colors to represent mud or stone. Its gains a +6 bonus to AC when being attacked by anyone but the swallowed victim and a +6 bonus on Stealth checks on the ocean floor.


Environment any ocean
Organization solitary, pair, or grove (3–30)

Conch trees are frequently cultivated as living barriers, unsporting hedges against unwanted incursions. After centuries of breeding and experimentation, they developed an instinct for discerning regular travelers among their groves from visiting prey. In the wild, entire schools of fish can vanish instantly over a conch grove.

Conch trees reproduce by implanting a single seed in a partially digested corpse. The corpse is then expelled so the seed can absorb nutrients before sprouting and taking root. Conch trees never stop growing, but an average adult specimen is 20 feet tall.


Price 50 credits Weight

Stralleth comes from the respiratory organs of the dangerous conch tree, unique to ocean floors. When the pulp is dried and alchemically treated, it yields handful of bitter turquoise crystal.

With practice, a creature can convert water to breathable air as it passes over the crystals. A single pinch of this crystal placed in a creature’s mouth allows the creature to breathe air by taking in a mouthful of water for one hour.

The cost above is the price for a single pouch of stralleth, delivered in dry seaweed to preserve the crystals. A pouch contains four pinches.
