First off, This is an actual working mod. I know I've tried to overhaul the coop in Dark Souls II and have failed but this mod actually works.

This mod works on steam deck!

This mod does the following:
Adds an infinite invading item (No more blue acolyte needed!)
Adds every multiplayer item to your inventory so you can coop / PvP to your hearts content
No multiplayer barriers (Courtesy of cooledbee who created a better version of ds2 coop overhaul)
No multiplayer timers (I even went and made it so enemies no longer subtract time JUST to be safe)
Small note about no timers. Your phantom will be dull like you're about to leave. this is because i have the timer set to -1 which is close to 0

This mod has a good chance to softban you. if you and your friend use the mod at the same time this isnt an issue as you will both be on the softban servers
Note: There's stable private servers you can play on! You can find it here:

If you get invaded by a cheater. Run behind a multiplayer barrier and wait for them to leave. This mod has an unintentional safe guard against cheaters

If you have any questions about this mod feel free to ask in my discord!
