We should be grateful they are not biting every unicorn they encounter, to spread the Curse of Cetaceathropy.![]()
Why have you cut Jump out of the Hippocampus and Dolphin form's stats?
Also, I just noticed I forgot to capitalize "Swim" and "Powerful charge" in the Dolphin-form's stat line. Furthermore I'm thinking the line "In equine form the sea unicorn gains the Amphibious quality so it can breathe air but loses its blindsight." reads a bit clumsily.
Could we change that passage to:
Dolphin Form
Speed: swim 80 ft.
Attack: Horn +10 melee (2d6+10)
Full Attack: Horn +10 melee (2d6+10)
Special Attacks: powerful charge 3d6+13
Special Qualities: Blindsight 120 ft., darkvision 60 ft., immunity to poison, charm, and compulsion, low-light vision, scent, spell-like abilities, wild empathy
In equine form the sea unicorn loses its blindsight but gains the Amphibious quality, allowing it to breathe air and water.
That looks easy. It's just an SRD unicorn with a 120 ft. (good) fly speed slapped on to it and Temperate Mountains for an environment.
The only real question is what shall we change its collective noun to.
A flock on Unisus sounds a bit mundane.
A Flight?
An Ascension?
A Summit (as in a mountain peak)?
Oh, and the Sea Unicorn probably shouldn't have "*Sea unicorns have a +4 racial bonus on Survival checks when tracking by scent" under Skills. I think that was a holdover from the Palomino Unicorn.
I caught that once. It was a summer I'll never forget...![]()

I sure did, but I blubbered uncontrollably afterward.![]()

Wanna borrow any of this from its pegasus parent?
Spell-Like Abilities: At will—detect good and detect evil within a 60-foot radius. Caster level 5th. [It already gets detect evil from its unicorn lineage.]
Skills: Pegasi have a +4 racial bonus on Listen and Spot checks.
Agreed to "one square mile." The org also needs changing from "grace."
Should we add something like powerful charge, or do we think that's just a usual diving charge (I feel like there is such a thing in the SRD, but I can't find it right now).
I'll fix the org. We decided upon "summit" upthread.
I'm not sure about the SRD, but I found the following:
Power Dive (Ex) If a flying warforged raptor makes a charge attack against an opponent on the ground, it can make a full attack.
Power Dive (Ex): At 6th level, an Aglarondan griffonrider *SNIP"*
Power Dive [General]
You can fall upon an oppenent from the sky. *SNIP"*
Swoop (Ex): A noctral can execute a swoop attack *SNIP"*
