Maybe not straight away, as you have said that you are new to modding, but i would be awesome for some new creatures to be added that we can hunt or unique varients of existing creatures to to give the mod more variety.

the first thing that came to mind was a contract to hunt down an ancient dragon matron, a female dragon guarded by a brood of smaller male dragons, she would have to be much larger than regular dragons and it'd be hard to balance a boss fight with 4+ dragons but that's the first thing that came to mind.

Maybe a big slaugterfish?

An ancient coven of vampire lords, each with unique abilities.

Thanks for the suggestions, they are all very good, I'll add them to the list of possible contracts :)

How about a wherewolf pack.

Can you make a version for skyrim special edition?

Maybe you could add an armor other type of identifying equipment to members of The Protectors guild.

What about a Chaurus? Plop one down at the end of a Dwemer dungeon, give the general area of that dungeon, call it a day.

Kill Bees ( ͡° ͜ʖ ͡°)

would be awesome to see mobs that are super powerful and super strong but also drop some really epic loot. Random weakness/strength and maybe even a cool randomized name. imagine you take the contract and run out to a clearing and when you get there you find a 3X normal size bear that shoots lightning breath and maybe even has tactical phases! I guess I'm looking for a random boss generator at this point...maybe theres already another mod....

a mysterious thief , maybe a vampire who's using his vampire's ablities , that can be great no ? :DD

Or a series of contracts that end up building to a bigger creature contract, ie Kraken or Giant Wyrm.

Maybe change Comstorn's armor? It's strange to see some random guy in Daedra armor at the docks.

Possibly make compatable w Open Cities. Also maybe add some contracts with multiple parts? Like "go kill this beast that this cult summoned, then hunt down the cult and its leaders" that would be neat
