Thanks for playing.
HP bar is a DevilutionX specific QoL (optional).
Caves do not have transparency.
Early on you found a shrine that repairs all you items (Time cannot diminish the power of steel).
Hellfire did not add an option to not randomize quests, that's DevilutionX specific.
Diablo 1 does not have item highlighting (we are working on this).
Mana is only used after casting spells, cast two in a row can get you to negative mana.
Warrior gets very little mana from potions)
We do have plans of improving the shop menus, but at least you seam to be enjoying that we made the scroll wheel work.
