Tritons are Company (2–5), squad (6–11), or band (20–80)
Challenge Rating: 4? (Standard 4HD centaur is CR 3)
For the most part, sea centaurs have no treasure (except for an occasional piece of jewelry), although 10% of them have acquired tritons' magic conch shells. When used by sea centaurs, these shells summon 2-8 hippocampi; they can also be used to send messages underwater within a halfmile radius.
Treasure: No coins; standard goods (jewelry only); standard items?
Tritons no longer have these conch shells. We could make them, though.
There is a 10% chance that any sea centaur has the ability to cast spells as a 1st-4th level druid.
Favored class: druid?
A sea centaur is 12 to 15 feet long and weighs about x pounds.
