Elden Ring has some incredibly difficult bosses. It is very likely that you will be destroyed by the numerous towering enemies that roam the Lands Between unless you're the one player who took a break to cool off Elden Ring Runes and not do anything against a very difficult early-game battle.
There's an optional field boss available in Limgrave known as The Tree Sentinel. In addition to being armed with a multi weapon Grafted Scion that kills you at the beginning, and the simple training knight that you fight prior to reaching the first area of the game The Tree Sentinel acts as Elden Ring's initial major challenge. The Tree Sentinel is a man dressed in gold armor, and riding an equine that is walking through the nearby woods searching for shit to kill. It's a tough guy to kill, and it's not the only time you'll encounter this character in game. You can, however, avoid this Tree Sentinel entirely if you're not at a high level or don't want to take on his massive golden halberd by simply getting away.
YouTuber InfernoPlus who creates videos of games that are meme-like and engages in popular debates InfernoPlus didn't seem to be too concerned over The Tree Sentinel, though. In fact In a recent Twitter video, Inferno seemed exhausted, they simply laid their backs on Elden Ring Runes for sale rocks while summoners did the chores.
