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]

Installation:

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:

Początkowo opublikowane przez 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.

Hey, thanks!

Any idea if it flags the username/account? So if I archive my current save and start a new one to play with the mod, I can later delete the modded save and go back to the original to carry on? Or if I have two computers with the same account, one with the mod and the other without, each with their separate saves, I can go safely (not gonna play at the same time on both computers)?

none of that is even necessary. The mod uses a different file extension on the mod save files than regular saves, keeping the two completely separate. You use the mod launcher to play Seamless and the regular launcher to play vanilla. It is possible to port a vanilla save to the mod by making a copy and changing the file extension to the one the mod uses, but you can't port from modded to vanilla without consequence.

So basically the only thing I should worry about is using a save from the mod on the original game. Cool!

For some reason after playing for a bit with people and creating a new character, I now can only access my vanilla characters after launching seamless coop. I checked my save file and have both the co2 and sl2 saves there so I am not sure why I can't seem to access the save file for my seamless coop characters?

I'm getting a "failed to find all necessary game signatures" error even when I run it as an administrator. What do I do? The game was recently updated so that can't be it.

cant use them in co-op anyway, but for me i generally have to die to the starting boss just outside for them to pop up, or they'll eventually show up in the hub merchant shop

The latest update for the mod, I believe, makes it so you can use spirit ashes once per rest

What changed in 1.4.2?

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.

IM REALLY SORRY BUT YOU ARE CLEARLY STATING THAT YOU ARE PURPOSEFULLY CUTTING THE PLAYERBASE OF AN OFFICIAL GAME MAKING THE INVASIONS AND FINDING COOP PARTNERS MATCH UPS LONGER AND LONGER THEREFORE RUINING EXPERIENCE OF THE GAME FOR OTHER PLAYERS WHO DOES NOT HAVE OR NEED THIS MOD AND DIMINISHING THE PLAYERBASE OF THE ORIGINAL GAME. PROVE ME WRONG.
I HOPE FROMSOFTWARE HAVE SOME COMMUNITY MANAGERS THAT WOULD SEE THIS RUINATION AND CUT IT DOWN.

no need to reply to my message as im stating the facts.
