As such a list does not yet exist on the internet---at least not as far as I am aware---I decided to waste invest my time and map out this game's potions, runes, and weapons. The following list does not contain arrows (neither normal, nor artificed ones) although this could be adjusted in a future update called "All Collectibles" as necessity arises.

While I was very thorough and did check all the guides and playthroughs I could find, there is no final guarantee for its completeness. After all there could be some secret so well hidden within this game that nobody on the internet yet knows about it. This holds in particular for the health potions and the life upgrades as only the magical weapons are fully listed in the manual. If you manage to find something not listed below please tell me; either in the Prince of Persia speedrun discord (linked in this game's navigation bar on the left) or message me directly (my discord name is just "toca").

Last but not least, if the description of where to find a certain thing is not sufficient you may left-click on its name to see an image of it. This will hopefully clear up all potential misunderstandings. Note that the terms for the runes are the ones from the official manual. For the save points (as well as level start and end points) I created a spreadsheet containing all coordinates. The coordinates can be viewed using the cheat table from the resources tab.
