Another aspect of the gameplay of "Undying" - and one which gives it a similar ambience to traditional role-playing video games - is that along with its set of offensive weapons, the player is able to use a wide range of magical spells. Spells consume a certain amount of Galloway's magical energy, or "Mana", which is represented by a flask icon and corresponding number on the bottom center-right of the screen. This energy slowly regenerates itself over time. Magical tattoo pickups called "Arcane Whorls" permanently increase mana regeneration rate, while amulets called "Mana Wells" increase maximum mana by 10 up to 200. Once the player acquires a spell, it may be boosted in power each time the player finds an "Amplifier Stone", which are purple glowing crystals scattered throughout levels of the game. Galloway can simultaneously wield weapons in his left hand and cast magical spells with his right; the power of both the weapons and the spells increase as the game progresses.
