Any way to tell difficulty level of monsters and quests?

[Lampros]

I just saw a bunch of mammoths and giants and attacked, and I got crushed instantly. They were near a main city, so I thought it was okay to tackle them? Is there any way for me to know?

Also, the same for quests. I just did kill a bandit for Saadia or whomever she is quest, and it took me like 7-8 tries to succeed, and that was probably a bit too high level for me at around level 5.

In fact, I would've not succeeded if I didn't have a mod that let me use 2 followers.

their isnt level systems for quests and monsters, well their is its just the game balances them to your level so the reason you got demolished by giants is because their giants, A.K.A. Powerful as $h!t.

In the Vanilla game, almost all the enemies you'll encounter in quests are leveled. That is, they're level depends on your level. You won't start facing certain enemies until you have reached a higher level.

However, each creature exists in a possible range of levels, with a minimum and maximum, so creatures like Giants who will be spawned regardless of your level are insanely powerful in the early game, because even at their lowest possible level, they are much stronger than you will be, probably until something like level 25 (I don't play vanilla though, so I could be remembering this wrong).

You'll find that side quests are more likely to have level limits I think than main quest lines.

Do note that if you get into modding, this can change. Some quests, such as SkyRe, will play with enemy levels for certain areas, and you won't know ahead of time, which can result in walking into a surprise ass kicking.
