Rage Potions? Where???
 

I have come across just one shop selling ONE rage potion, the other shops just seem to have mana potions but not rage potions!
They seen to be in short supply and the problem is that I need them as I am a Paladin and whenever I want to use the chest I am met with the ':evil:Not enough rage!' screen.

In the game, there are a couple rage fountains too. Very few, though. No rage? Then you must do something wrong. Every attack on your enemy will generate rage, every damage you sustain will generate rage. Later on, one of the Lina's skills will generate rage, one of Reaper's skill will suck some rage out of your enemies.Inquisitors can generate Rage every 2 turns etc. If you are careful, you will never run out of rage. Be patient, learn to play and rage won't be a problem anymore. As a mage, I usually need more mana, while I have enough rage.
