to be honest it is actually easier to mod multiple armor / weapons to sell for over 15 million to replenish your mana supply to be able to upgrade armor/weapons/pets. I can make weapons that sell for 2.1 billion mana, but problem is there is a natural cap for your bank in game of 15 million mana ( i could be wrong about the natural cap, it probably can be modded as well i just haven't figured out which set is for that yet)
Though if you want a crash course / helping hand while you are hex editing, get at me either on here or on XBL with GT of Raklik , after doing this a couple of days now im starting to see different snippets of code and recognize what things are now the more that i mod. Willing to pass on what i've been able to teach myself over the last week
