I like the idea of beasts that require superior numbers to take down,
Maybe a couple of trolls that heal, a fire spraying dragon, a fear paralyzing basilisk, a venomous spine shooting manticore, or yes a giant spider.
They’d all be awesome hunter quests.
Also maybe we could fight something defence focused like a nasty race of dirty dwarves/gnomes with daggers, blowpipes, and large shields, that steal children, tools and gems.
