The revised statblock does add more gameplay elements and opportunity for further adventure. You should also clarify a few things though.
Cursed Nature- does remove curse transform it permanently or just for some amount of time? If it is an eagle now, why does the other part still matter about a humanoid heart? Does this part even need to be listed here or move it to the Devour Heart part?
That's meant to be permanent. I'm pretty confident in saying that in 5e the omission of any timeline defaults to permanency (i.e. things like "you're dead" or "petrified").
I originally had it under Devour Heart, but was playing around with things. I think you're right, it's better placed there.
Devour Heart- It uses an action and regains all of its HP. That is a cool reason to stomp a down PC. Might be worth thinking if it should be healing up to the dead PCs HP instead of a full heal on the peryton. If the PC is restored to life, say next week when the party gets to town, does the peryton know somehow it is back alive?
One of my goals is making monsters easier to run – or in this case, as I'm adding a bit more complexity, not making that a burden on the GM. Tracking
how many HP a PC has and doing the healing math just seemed like unnecessarily burdening the GM... especially when a peryton only has ~33 hp and 2nd level PC has ~15 HP.
Like
@MonsterEnvy said, the stat block (due to removal of resistances and HP remaining equal) is a bit weaker than the original just looking at the straight maths. So I'm ok making Devour Heart a bit nastier.
A more poetic way to phrase this is that it's not about the "
strength" of the heart, but it's the
malicious act of tearing a sentient being's heart from their chest and eating it.
Cool. You’d want to telegraph the bit about Devour Heart somehow. Maybe a rumor the party hears in town. And/or they stumble upon a body with its heart devoured right before encountering a peryton with blood around its mouth. I really like remove curse as an alternate way to defeat one as well.
Yeah, that's definitely worth pointing out. That kind of foreshadowing has become instinctual for me as a GM, but absolutely.
The
remove curse idea I'm playing with are that there are a handful of D&D monsters who are described as the result of a curse, so why not make an "offensive" use for that spell embedded right into the monster writeup?
