Nothing wrong with summoning NPCs or other players. If you want a more difficult fight, then don't. It's essentially the easy mode. Your level is also going to impact how difficult the bosses are. It's easy to over level in Elden Ring.Finally done with Limgrave and Stormveil. I think just need to do some minor stuff like kill those three giants in the huge bridge just for completionist sake.
I really had more trouble going through Stormveil than the main bosses itself. I thought it would be more difficult because of all the stuff I’ve seen online especially about Margit. Turns out they’re super easy if you just summon spirits and an NPC like Rogier and Nepheli. I don’t know if there’s like a souls etiquette to not summon stuff since most of the videos I’ve seen online has been doing them solo.
Overall, Stormveil was amazing especially going in blind. So many secret stuff packed around that made me go wtf. Some secrets I even found out by falling to my death and made me think if that was even supposed to be there. I might even go back and farm those knights for the banished armor set since the stats seem pretty good. Problem is that they’re heavy as hell and I need to level my endurance. Also, another Crucible Knight ON A CLIFF fuck me. I died a couple of times on that one alone.
The boss fights definitely get more difficult in the late game as well.
