Is there a trick to a boss in 2nd dungeon? He seems vulnerable to air, and deals primarily earth damage. I made a lot of medium EP and AP potions, but taking a potion just exposes me to a counter-attack, and the EP potion itself does not restore enough energy to cover for the loss. Best I can do is get the boss to around 12-14HP and then I lose. Taking lots of potions in advance seems pointless since the game resets the all elements to 7.3 at the start of every fight, even though I have 7.0 normally. Unless I’m missing something there doesn’t seem to be a way to increase it beyond 7.
