Talk:Swiftness Potion

Stacking
I noticed last night (November 17, 2013) that while running on Asphalt with Frostspark Boots equipped that a Swiftness potion does stack with them. Without the potion I am only able to slowly catch up to a dart fired from a Dart Trap with the Boots and Spectre Armor being my only movement speed items (the dart hits another block at the end of my 1000 block track, so I never actually catch up with it). However, with the same gear on and a Swiftness Potion going, I am easily able to outrun the dart even if I wait for a few seconds before I start to run. Without the boots on and the buff going, it is much harder to catch up to the dart, the boots and potion on, but with the Spectre Armor off, I am able to outrun the dart easier again. So either they stack, or the Asphalt causes them to stack.

 * This effect does not increase your maximum speed, but rather your acceleration. Therein, Hermes Boots and this potion do not stack.

Wouldn't a speed buff and an acceleration buff stack even if they buffed different things? If they didn't stack, only one buff or the other would have an effect at all. --Tathar 21:49, 1 July 2011 (UTC)

Max Speed

 * This effect does not increase your maximum speed, but rather your acceleration.

I just tested it and compared the times. It does increase your maximum movement speed by the amount it should; and also changed the article to reflect this. Can someone with access to the code confirm this?
 * Yup, it gives you a 1.25 (25%) bonus to your movement speed. The bonus is the same type as the Anklet, Aglet and Necro Armor. In fact they all appear to stack multiplicatively. Olrad 15:44, 12 July 2011 (UTC)

Mounts
Does the Swiftness Potion have any effect on the acceleration or speed of mounts? --TheFrostSpark (talk) 18:04, 20 May 2016 (UTC)

Quick test with UFO suggests no.
