So going through some changes for Albertus.
He is no longer an old man, but a man aged around in his late 30s, who has clearly been overworking way too much, resulting in his "old age". His backstory has also been tweaked; The rumour that I made in my first Albertus post is indeed still a rumour (the part where he was raised by Dwarves). The truth will be revealed when the heroes finally confront Albertus in Skull Cove Citadel.
Master Spells will only correspond to the main elements that are stored within the Omni-Gem, so only Fire, Water, Earth, Wind, Light, Darkness. Lightning-based Spells will be classified as Wind. Spells that use metal weapons, like Shadow Blade, will be Earth. Ice-based Spells will be Water. Time stopping or slowing will be Light. Explosive Spells will be Fire. The only Spell I can think of at the moment that will be Darkness is Magic Card (Magic, dark arts... Blargh...). This is of course just a very general classification. When the time comes to reveal a Spell, I will list the corresponding element. So do not worry about it.
