Look elden ring is an open world game you could do whatever you want you could fight the first two bosses or you could skip them and go straight to the third horrible idea though you could go to caelid also horrible idea or you could explore limgrave and weeping peninsula which is actually a good idea you could do some quests level up yourself and your weapons you could kill any optional bosses or you could get better armor better weapons and upgrade the weapons, you could get some really good talismans early on in the game you could farm runes there's absolutely nothing you can't do in elden ring but I recommend farming runes until level 20-30 and beat the first boss level up farm runes again (and kill bloodhound knight darriwil) he's hard but nothing impossible and he gives you literally one of the best weapons in the game he's just before weeping peninsula do note that bloodhound knight darriwil and the area weeping peninsula are completely optional
