page 53: Manticore
Not necessarily a bug/mistake.
Just want to point out if you have a large party, say 7 adventures, you end up with a very fast(almost comically so) manticore, that can run through its entire moves list in 10 seconds(1 round).
Maybe add some health scaling instead?
(this might be a common problem with using ferocity as the main scaling for enemies)
I don't think the game is built around 7 players (very few ttrpgs are). You'd have only 3 initiative cards to go around for npcs and monsters, and considering sone encounters asks for double the number of npcs against the players this would mean the npc squads would be very large. You'd also shread monsters unless you make their ferocity higher, which would need a bigger initiative deck.
I'm running a game with 5 people and i'd argue that the game works best between 3-5 players. It gives the gm some wiggleroom for building their encounters without it "bloating" the game.
But on a side note, it is a manticore mutated by the portal, so you ciuld easily handwave it's speed as it being a part of it's mutation and its berserking mood
