Big blue mana magic potion for larp o cosplay. What is a magician without magic? Someone with a stick, grandiloquent words and, possibly, very scandalous clothes with runes. No practitioner of the arcane would enter a dungeon with spent batteries or without a mana reinforcement. Potions of magic! That's what a proactive magician carries in his knapsack or belt. Magic concoctions. Healing, magic, stamina, revive ... Make sure you take one with you and face the adventure. Link would not have evolved from being a pixilated dwarf in Zelda to the HD if he had not had a reserve of potions with which to face the Final Boss. The hero would not have reached the Diablo III version.
