Don't attack

-Giants
-Mammoths

I got my ace handed to me more than once being brave and trying to take them on, I killed a giant, but his buddy blindsided me with a shot that sent me into orbit....

What level were you guys at roughly when you could kill them no problem? I'm level 10, primary weapon is a bow secondary I swap to sword and fire or sword and heal. Using light armour only and alchemy is a big one but still in the lower levels of it.

Go to Sleeping Tree Camp , it's too easy . At least it was for me !
