This is currently an experimental build so expect a few bugs.

(ver. 2.0)

What's new in ver. 2.0: (Updated on 5/23 @ 4PM ET)
- Increased the player count to support 127 players (note this has only been tested up to 15)
- Added PvP, PvE, and boss rush modes. You can access these with the shrines at rountable hold and the Limgrave and Caelid areanas
- Fixed some inconsistencies with packet order
- Modified the way clients initially connect with each other
- Removed the Varré quest line skip
- Added visual effects to rot
- Changed some mod icons
If you'd like to use this experimental version, then you must replace **ALL** mod files *including the launcher*. A clean install of seamless co-op is strongly recommended.
Not compatible with mods; The seamless co-op launcher is required for functionality. Wait for stable release if you require usage of other mods. 

Info about the mod:

- Mod which removes all multiplayer boundaries and allows for connections to persist after death.

- Play with friends from the tutorial to the very end of the game, with synchronized progress, and no re-summoning or interruptions.

- Enemy scaling is fixed (it didn't work at all previously). It now mimics Elden Ring's (25%/50%/75%) buff on enemies for 1, 2, and 3 co-operators respectively.

- Voting enables synchronized fast travelling in the game. All players in the session must agree to warp to a specific destination. Once the vote passes, all players are warped at the same time.

- Map waypoints are now synced with other players in the session, making it easier to communicate where you'd like to explore or areas of interest.

- Evergaols, portals, etc. now all work correctly and affect other players in the session allowing you to tackle usually restricted areas in multiplayer.

- When dying in a boss fight, you will be unable to re-spawn and enter a spectator mode until either the boss is dead or every other player dies. This lets bosses keep their challenge while allowing you to stay together in a multiplayer session.

- A stack-able debuff mechanic called Rot Essence has been added. It is acquired on death and can be removed when resting at a bonfire. There are currently 3 varied effects that can stack both with others and themselves.

Frequently Asked Questions (FAQ's):

Q) Can the mod get me banned?
A) No, the mod doesn't connect to the matchmaking servers and does not use FromSoftware's online services and therefore you can't get banned for using it.

Q) What is the player cap?
A) The maximum player count in a party is 127 (1 host + 126 guest players). Only tested up to 15 player simultaneously in ver 2.0.

Q) Are there invasions?
A) No, there are no invasions.

Q) How do items work?
A) Items are unique to every player. If boss drops a talisman pouch for example, everyone will get it. The same applies to items found in the world and enemy drops.

Q) How do sites of grace/bonfires work?
A) If one player sits at a site of grace anywhere in the world an enemy/world reset will occur for every player. If a player is fighting a non-open world boss at this time, they will be placed back outside the fog wall and the fight will be reset.

Q) Is progress shared?
A) Yes progress is shared. But it only applies to actions you do whilst in a player's world - for example if you start a fresh character and join a player to kill an end-game boss, only that boss will be dead in your world and you won't inherit all of the other player's progress they had before you joined.

Q) How does it work with the anti-cheat?
A) It doesn't, the mod uses a separate launcher which runs the game without launching Easy Anti-Cheat.

Q) Can I use other mods?
A) Yes, however for regulation / param file edits everyone in the party must have them active in order for them to be visible. (e.g. if just 1 player uses a randomizer, it will only work for that player). Also, not in experimental build 2.0

Q) Does this worked for cracked/pirated games?
A) No.

Q) Isn't this just easy mode?
A) Not necessarily, while co-op play does make the game objectively easier, it's also a completely different way to play the game. There are plenty of "easy mode" mods out that that just give you high health/damage. This mod will be easier but is made in mind of those who want to play the game the whole way through with friends. It has been designed with fun in mind as opposed to reducing the challenge.

Q) Can I modify or redistribute this mod?
A) No.

Q) Can I use my save game from the base game?
A) Yes[/b]

Compatibility with other mods has not been tested. You may use other mods, so long as they do not interfere with the multiplayer aspect of the game, or edit any of the items the mod uses to function.

• Download the mod from the 'Download'[www.nexusmods.com] tab.
• Extract the package you downloaded, and move the following files to your Elden Ring folder (usually in "C:\Program Files (x86)\Steam\steamapps\common\ELDENRING\Game").

Usage:

Origineel geplaatst door Fang:

Set the coop password in SeamlessCoop\cooppassword.ini
The host must use the Tiny Great Pot to create a session.
At that point, the other players can join using the Effigy of Melina.
You should spawn in at a point nearby the host. Any player can leave at any time using the Separating Mist
- If the host uses this item, the session will be disbanded and all players will disconnect.

This mod is currently in beta (ver. 1.01) so expect a few bugs.

Updated @ 11AM EST (GMT-5)
What's new in ver. 1.01:
Fixed an issue which prevented people from joining as co-operators from non-MP enabled areas
Fixed a crash caused by hovering over waypoints being deleted by another player
Adjusted enemy scaling, and added enemy posture scaling
If your character does not have the mods items, they are automatically given to you
Fixed some typos in the item descriptions

Q) What is the player cap?
A) The maximum player count in a party is 4 (1 host + 3 guest players). Increasing the player cap beyond this is out of the scope of this project.

Q) Are there invasions?
A) No, there are no invasions. You can PvP with members of your party if you like using an item to toggle friendly fire mode. Invasions are not possible in this mod. You're not connected to the matchmaking server so can't be invaded by anyone else. This isn't a design choice, it's just the way it has to be to keep modded players separate from the vanilla player base.

Q) How do items work?
A) Items are unique to every player. If boss drops a talisman pouch for example, everyone will get it. The same applies to items found in the world and enemy drops.

Q) How do sites of grace/bonfires work?

Q) Does this worked for cracked/pirated games?
A) No, I'm also not going to be supporting these versions so please don't make bug reports about it.

Q) Isn't this just easy mode?

There are plenty of "easy mode" mods out that that just give you high health/damage. This mod will be easier but is made in mind of those who want to play the game the whole way through with friends. It has been designed with fun in mind as opposed to reducing the challenge.

Q) Can I modify or redistribute this mod?
A) No, sorry. Please do not modify, repackage, or redistribute this mod anywhere without my permission.

Q) Can I use my save game from the base game?
A) You can, although it would require more work. As mentioned the mod uses separate save files by using the ".co2" file extension instead of ".sl2." Make a copy of your .sl2 file, then change the new copy to .co2. Once ingame, using Cheat Engine, spawn the new mod-specific items. Do not do this the other way around (moving your save from the mod to the base game) as you may get banned.

Friends and I are trying this out but instantly get a "failed to join session" when trying to join the host.

Figured it out, you need to go outside the tutorial area to the first bonfire next to varre, from there you can join

SO GOOD

[Choko]

Great mod, now From Software who only not behind in content creation but in programming as well. Might never see next game again. 🤣

[Dr. Raven]

It's unfortunate really that FromSoft couldn't be bothered to have the base coop system like this.
Instead just opting to copy-paste from previous souls games with very little changes and call it day.
Sure, the multiplayer side was never the focus of the game but then why bother to even add it in in the first place and make a half-assed attempt?

I get that FromSoft has never had the best technical side in developement but one would think that they would've learned something by now..

[phlux]

Best thing to happen to this game since the launch.

[wildnike]

I've been experimenting with common passwords to try and see if there are sessions to join. Having game night with some close friends is fun, but I was also wondering if there were people who'd just like anyone to come in. Though so far I haven't really had any success, even setting password=password.

Has anyone had similar results? Thanks.

[GermanyMan]

Mod is buggy as hell, Cant vote vor entering Evergaols, De-Sync hard after roughly 30 mins in Co-Op, killing bosses doesnt give you rewards sometimes, Enemies that are dead in hosts world stand there for you in T-Pose, Session gets unjoinable after 30 mins; need to re-host and connect again.

At frist glance the mod does seem to be good, but it isnt.

Usually im not into this "Opting out of invasions", i just tried the mod with a friend and his girlfriend as she isnt really good a t the game.

Yeah, you maybe didnt encountered a bug once but that doesnt mean it doesnt exist. Its buggy as hell for me.

Yep, exactly what i said, I didnt see any, never said there werent any. I am running the first version so maybe its something with the update if you were running that
