Since Master Of Magic is a game where they really don’t care about balance, I wanted to post some of the ways you can become overpowered. This usually involves making your own custom wizard, since none of the premade wizards have any OP combinations.
#1. 11 books of one color – version 1 – 11 life books, choose stream of life as the rare spell to start with. It will take a while to finish casting stream of life on your starting town, but as soon as you do, max out the taxes, because nobody is ever unhappy under stream of life. you will probably have enough gold to maintain the stream of life upkeep by alchemy.
Of course, you are going to have to cast stream of life on all your cities. Don’t forget to cast it on your outposts – they grow very fast!
#3 Combine Runelord and Artificer. Artificer gives a discount on casting Enchant Item and Create Artifact, and gives you those spells to start with. Runelord gives you a discount on casting Arcane magic spells (such as Enchant Item and Create Artifact). Combined, you can break items on your anvil for less mana than it takes to make them.
#5 9 books of sorcery. Sorcery Mastery. Conjurer. The books and sorcery mastery give discounts on casting all sorcery spells. Conjurer gives discount on summoning spells. Together you get (I think) a 60% discount on sorcery summoning spells.
People who have done this say that it makes a big difference in early exploring when you can summon a couple of phantom warriors to every battle.
#6 11 books of one color version 4 – 11 nature books, Gaia’s blessing. not as comprehensive as stream of life, but also less expensive to maintain. It takes a while, but then you discover that you have capitols with pop in the 20’s while your opponents are still in the teens.
