Well this would be dependant on what "Stat Potions" we are talking about here.
If these are "Minor Brews" then the loss is indeed not so great.
If these are "(Refind) Elixers" then it is a whole other matter. These are in fact some of the best loot you can get.
Unlike Purple Armor/wWeapons they stack and you can use more than 1.
Every time I get another Fury of Xotli on a HoX it is just 30 silver. If its a Rage of Xotli its only 20 silver even.
