Better Potion of Everlasting Vigour

You will still receive the potion as a consumable, however drinking it will apply the +2 STR to everyone in the party. When you swap someone into the party they will also be granted the +2 STR. This effect is retroactive, so if you install the mod after having already used the potion, it will still work and apply to everyone.

Unlike my Better Hag Hair mod, this mod simply applies the effect of the potion to everyone. The purpose was not to give everyone a freely chosen +2 to any ability. Both mods are so you do not have to choose who gets the increase, either for party flexibility (single player) or for fairness and less discussion (multiplayer). A reminder that +2 STR helps everyone to shove, resist being shoved and especially to increase jump distance.

I won't be making mods for every permanent buff, as the rest are rather minor and a little bit of choosing who gets it is still great fun. Just the Hag Hair and Potion of Everlasting Vigour are powerful buffs that can determine builds and feel bad if you don't get them.

The Mirror of Loss already allows you to choose the stat to increase, so there is probably no reason to make a mod for it - plus it is quite close to the end of the game.

The mod also changes the appearance of the potion (3D and icon) so it is easier to distinguish from Antidote and other similar potions.
