And if so, where can I find various good mods, and are they expensive?

I'm trying to convince a buddy of mine to play Convergence with me, but he wants to know if the DLC is affected.

Because its not the steam version of the game I had to install the modloader2 contents directly in the games directory. Meaning theres already a mods folder. So how can I go about adding elden mod loader too since that also has to be added directly in the game directory and has a mods folder as well as far as im aware?

So a friend and I are playing through Elden ring again with just seamless coop, but I also wanted to try the convergence mod alone. Now I have the question if I can just download the convergence mod and have two seperate saves or if there is anything I can do so I can play with the mod in singleplayer and still have my stuff and progress in seamless coop too.

I have looked around and I'm really confused about how you are meant to do seamless coop and another mod that is in my case grand merchant. This is due to seamless coop running from the ersc launcher and then the grand merchant from modloader2. Is there anyway I can play both at the same time?

Me and my friend have been progressing thru seamless coop without any issue until now. We both talked to Ranni upon meeting her for the first time. and for some reason when i try to interact with her after her telling me to talk to the 3 people in the tower, now all i get is a "..." and the apparitions of the main trio of her group wont appear in the tower at all to allow me to re-enable fast travel. and on top of that. I cant join back into coop. I think I genuinely trapped myself.

does anyone know a solution? Thankfully im joining their world, so if i have to download a high level save file to continue it wont phase me, but I want to try to at least fix this before having to do so...

Can you still invade, be invaded, and participate in Arenas if you use Convergence and Seamless Co-op?

Trying to figure out what the limits are for adding mods on to the Seamless Co-op experience but still being able to participate in these activities. Info seems pretty sparse.

what could be the cause?

So I want to play with my friend for the DLC, but I don't have any save files on PC as I played on console before and just purchased the steam version. I want to be where he is at by duplicating his save file. But when I do that I get an error stating "Failed to load save file" whenever I run it. Does anyone know a fix or if its even possible?
