Notable here is that only the effect of very last one of the stack can be recreated. The second type works on most items that have no confirmation box as well as on items with a confirmation box such as boss souls, but type 1 should be used for those. Type 2 - Items without confirmation box
In this speedrun, it will only be used to duplicate Homeward Bones. Instead it uses the item that you chose in your inventory but gives you the effect of the item with the confirmation box. If you now press START before the confirmation box appears, and use another item in your inventory (preferably Estus Flask or Darksign), the confirmation box of the item in your hotbar will still appear but actually confirming the use now does not consume the item in your hotbar. Perform an action such as parrying, rolling or using a lever and queue up the use of the item by pressing "X" towards the end of the animation. To execute this, make sure you have the item you want to dupe highlighted in your hotbar first. The type 1 allows you to infinitely use items with a confirmation box, like boss souls or Homeward Bones. This is the most common, easy and known duplication glitch in Dark Souls. So when you now use either of these attacks you will get the ones of your right hand weapon but still have the damage of your left hand weapon. Since this is normally not possible and a bow normally doesn't have a running and/or rolling attack, the game retrieves this information from your right hand weapon instead. The glitch is essentially starting an animation (usually jumping), queuing up the two-handing of a bow in the left hand (while performing that animation) and then switching out the bow for another weapon so that this newly equipped weapon is two-handed in the left hand instead of the bow. The moveswap glitch allows the player to transfer the running, rolling and plunging attacks from one weapon to another and is commonly used in speedruns since it can double the damage output when used with the right weapons, in this case the Estoc is used since its running attack hits twice. If for example you perform the warp glitch in Firelink Altar, it will put you at the default location of that area: inside the Kiln of the First Flame.
When it does that, the game doesn't know where you've warped to, so it puts you at a default location based on where you were when you warped. The game won't let you continue playing online while being in an Xbox Live party and will force you back to the main menu. To perform a warp glitch, you first need to play online, then use a warping item such as a Homeward Bone or simply die and create an Xbox Live party during the loading screen. This makes it an essential item to quickly dispatch bosses. Because of the damage calculation done by the game, a 50% increase of your AR usually results in a damage increase varying between 100% - 150%. The Red Tearstone Ring increases your Attack Rating by 50% when your current HP is below 20%. While this technically makes this run online, no actual online gameplay mechanics are used.
Secondly, an internet connection plus an Xbox Live Gold membership is required since the method used to perform the essential warp glitch involves forcing the game to switch from the online to offline mode.
Contrary to popular belief, the Kiln Skip is still possible on the current patch of the game, but only for the Xbox 360 using an alternative method, making Xbox 360 the only platform viable for this speedrun. The Kiln Skip allows you to skip the four Lord Souls, effectively cutting the game in half. The route is using the Great Club combined with the moveswap glitch and Red Tearstone Ring (RTSR) as the main damage source. Any% Kiln Skip is the fastest way to beat Dark Souls by abusing a console-exclusive warp glitch.
