Duskruin's around the corner - if you're doing the arena and find yourself out of stamina in the midst of battle, there are alchemy-made products available to make sure you can get through the battle without having to pray.

I happen to be the only person making them, so here's what I have in stock at my shop in Mist Harbor (lich room 12270):

Light red tonic (21) - 10,000 silver - restores 100 stamina. 3 doses. (level 40 to use)
Blood red tonic (1) - 20,000 silver - restores all stamina. 3 doses. (level 60 to use)
Glistening brown crystal disk (1) - 15,000 silver - adds +20 to stamina regen. 3 rubs. (level 40 to use)
Glittering brown crystal disk (7) - 25,000 silver - adds +30 to stamina regen. 3 rubs. (level 60 to use)

I'll try to make some more 1107 potions (turbid aquamarine potions) before Friday as well. Currently sold out.

Thanks!
