Hey there,
The world feels more alive and a fair bit denser than Ow1 but there's more that can be added.
The interactive scale of animals is somewhat there.
Aggressive - neffer etc
Passive - the fluff ball who's name I forgot
Coward - pearl birds on low health
Animals need to both hunt one another and be apathetic in zones like rivers.
A predator to hunt the neffer and pearl birds would make sense.
Also something like ducks that have nests hidden in the barley as a cowardice bird, say half the size of a pearl bird or less.
Smaller beasts that scamper from you.
Eg. Hunting a frog, toad or salamander to produce the alchemical needs for the explosives and traps.
We already have the pygmy goats but they need both predator and should instantly flee when spotting anything bigger than them outside of other grazing animals.
An interim creature between the phoenix and neffer would be a reasonable miniboss both in challenge and filling out the niches.
A pre apex predator.
This would also allow for hunting quests ala Monster Hunter.
"This beast is impeding travel/farmland etc. Hunt with discretion"
In the mind of a far future update
