its hard to justify at such an early game stage, but you arent fully ready for the next biome until you have backups for all your best gear. 2 sets of armor, weapons, equipment, in order to fight your way back to your body.

and since you are just on meadows, getting more deer kills doesnt seem that hard. you will use deer meat probably throughout the blackforest and swamps, and deer hides as well. deer antlers also make the mallet, which is a good entry level weapon against skeletons.

but yes, 2 star enemies represent a sudden spike in difficulty, especially considering that blocking and armor absorption are not linear. a 2 star enemy is probably more like 4+ times the offensive threat of a 0 star.
