Blue Sentinel is a mod for Dark Souls III, created by LukeYui
Blue Sentinel is an anti-cheat tool for Dark Souls III, it will protect you from malicious cheats, flag players who use them, and allow you to kick them from your world.

What does it do?
This tool aims to identify cheaters and mitigate the impact they have on your online play, through a few different methods:
Detecting stat and level abnormalities of people in your session, allowing you to remove the player with cheated stats or disconnect.
Preventing dangerous effects (such as curse) being applied to you by other players.
Preventing a wide range of exploits, including multiple crashes.
Blocking invalid items from being picked up, or being given directly to you. (a.k.a "Item Inject")
Preventing a wide range of bullet-related frame rate drops.
If enabled, it can autokick detected cheaters when hosting.
If enabled, it can backup saves every time a new session is established and store a set amount of backups before deleting the oldest.
It will flag alternate accounts of people you have blocked
In addition to this, if you use the overlay, it will display the other players in the session, along with their steam profile names.
For more details on what Blue Sentinel does in the background, see below, note that this is not an exhaustive list and BS has hundreds of patches across multiple different categories:
Invalid items cannot be dropped to you, or given directly to you.
Fixed 2 crashes associated with equipment packets
Fixed 5 crashes related to player coordinate packets
Fixed 3 crashes, and 6 exploits associated with item packets
Fixed a crash, and an exploit involving a type of world flag packet
Fixed a memory allocation error with player initialisation packets
Fixed 2 crashes, and an exploit, involving player structure packets; Also prevents players changing their SteamID
Fixed 2 buffer overrun crashes relating to world initialisation packets
Players cannot apply custom effects on-hit such as curse
Fixed a out of bounds crash involving WorldChrSync initiation packets
Fixed 4 crashes related to player animation packets
Fixed 2 crashes related to enemy load synchronisation packets
Fixed 2 crashes relating to player bullet initialisation packets
Fixed 2 crashes relating to NPC behavior packets
Fixed an exploit that allowed players to apply effects to you (a.k.a "Autopilot")
Fixed a crash related to irregularly sized packets
Fixed 4 crashes, and 6 exploits relating to "MsgMapList" events. (e.g. "Force Animations")
Removed old netcode which allowed malicious users to modify other's soul count
Removed old netcode which allowed malicious users to modify the "humanity" other players
Fixed over 10 exploits and crashes involving the 'NetPackingVector'
Multiple packet validation checks, trying to fix both common and more 'unique' cheats.
Why should I use a protection tool in (current year)?
The cheating scene in Dark Souls has moved on from simple annoyances like cursing and one-shots to more malicious intent (such as crashing, banning, ruining saves etc)
Unfortunately, the item give cheat (aka Item Inject) was just the tip of the iceberg in this sense. Dark Souls III has some serious network vulnerabilities that can get your account banned or even cause lasting damage to your PC. I have reported all of these to the publisher and developers however it doesn't look like they will ever be addressed, it's only a matter of time before these security issues become popularised / public and Blue Sentinel offers a very high level of protection against these exploits.
I would recommend that every player who wants to play online uses a protection tool, and Blue Sentinel offers the greatest coverage against both well-known and obscure exploits.
If you have the overlay enabled, Blue Sentinel will flag users in your session. There are 9 different flags a player can get:
[Blocked] - The player connecting has been blocked via Steam*
[Blocked Alt] - The player is family sharing the game from an account that you have blocked**
[Malicious] - A check in Blue Sentinel has detected irregular data being sent from the player
[Cheating] - Blue Sentinel has detected that the player has a greatly unfair advantage - Reserved for non-downscaled phantoms
[Borderline] - A check in Blue Sentinel has detected irregular data being sent from the player, but it is indistinguishable from extremely high latency
[Invalid Stats] - The player has modified stats that are inconsistent with their soul level
[Impossible Stats] - The player has modified stats that are impossible to achieve through normal means, but have a normal soul level
[Kicked] - The player has been kicked through Blue Sentinel
[Glitching] - The player is abusing exploits (or using "glitches") such as infinite stamina with the Ring of Favour glitch, or avoiding the estus recovery animation to gain a frame advantage
*Dark Souls III will usually kick the player, however it takes 5 minutes between blocking the player and updating in the game.
**Within the ini file, there is an option which allows you to treat blocked alts as normal blocked players, refusing the connection when they join.
Blue sentinel tries to pick up players abusing some glitches and exploits in PvP. I've erred more on the side of caution here, so Blue Sentinel will not flag a glitch if it's not absolutely sure whether the player is glitching or not to avoid false flags. Please note that glitch detection is *disabled by default* within the ini file.
Not all glitches are detected, only the ones that seem more damaging to the online play. This is a balance between: How easy are they to perform; How popular are they amongst the community; What are their impacts on normal PvP? So far, Blue Sentinel should be able to accurately detect:
Some variances of the "bow glitch"
Illegal sacred flame grabs
Weapon art swap with "Parting Flame"
Weapon art swap with "Repeat Fire"
Infinite stamina with ring of favour rapid equipping/unequipping
When a player performs one of these glitches, they will get the [Glitching] flag. To avoid abuse (e.g. someone only kicking for 1 glitch detected a while ago because they are losing) this flag will expire after 10 - 15 seconds, but will be reapplied if the player continues to abuse glitches. If you use certain glitches yourself whilst using Blue Sentinel, it will turn the detection for other players off.
People have expressed concern about the glitch detection, however this is an optional flag and only accounts for <0.5% of Blue Sentinel's actual function.
Can this soft-ban me?
This tool cannot give a soft-ban by itself. To be clear:
Blue Sentinel does **not** modify Dark Souls III's code in any way*
Blue Sentinel does **not** disable Dark Souls III's anticheat
*The "SkipLogos" setting in the ini file does do this, but it is a safe edit, and will not cause a softban.
How do I use it?
Download the mod from the Download page
Extract the package you downloaded, and move the following files to your Dark Souls III folder (usually in "C:\Program Files (x86)\Steam\steamapps\common\DARK SOULS III\Game"), it should contain:
xinput1_3.dll - The mod itself
BlueSentinelPref.ini - An INI file where you can change some mod settings
To uninstall the mod, you just have to remove these files, or if you just want a temporary uninstall, rename "xinput1_3.dll" to something like "BlueSentinel.dll", then change it back when you want to use it again.
When the mod runs for the first time, it will create a directory called "Blue Sentinel" in your Dark Souls III folder where logs will be stored.
