Adventures in the Borderlands
Potion of Speed
This bubbling blue potion confers a burst of speed to the drinker.
When you drink this potion, you gain the effect of the haste spell for 1 minute (no concentration required).
Until the haste effect ends, the target’s speed is doubled, it gains a +2 bonus to AC, it has advantage on Dexterity saving throws, and it gains an additional action on each of its turns. That action can be used only to take the Attack (one weapon attack only), Dash, Disengage, Hide, or Use an Object action.
When the effect ends, the target can’t move or take actions until after its next turn, as a wave of lethargy sweeps over it.
