1: Make two wizards (use two accounts if necessary). They will be referred to as Bloody and Toaster because CharA and CharB are boring.
2: Buy a Wizard starter set for Bloody (40FG)
3: Buy Dia (120FG), Moon (160FG), and DSphere(10FG) for Toaster. Total FG spent = 330. If you're patient I'm sure you can get moon for 150, then use the other 10 to buy a Sup DEF.
4: Farm godlands for pots with Bloody, giving all pots to Toaster. Repeat until Toaster is 4/8 (SPD, DEF, ATT, DEX)
5: Switch to Toaster and farm godlands some more. Give all pots to Bloody until he is also 4/8 (SPD, DEF, ATT, DEX)
6: Once both Wizards are 4/8, buy Astral/MNova/Elder/Para HP for whichever has the better roll (we'll assume it's Bloody). Then give Dia/DSphere/Moon/Sup DEF to Toaster. It's a good idea to buy Toaster a Para HP too.
7: By the time you have 2x 4/8 Wizards, you should be skilled enough with them to take on events with a group, or even solo. Take Toaster through godlands and events, trading everything for potions to give to Bloody. The goal here is to get Bloody to 8/8.
8: Once Bloody is 8/8, buy him WC tops (which are crashing, so by the time you have a 4/8 and 8/8 Wiz, they'll prob be like 30DEF for Cosmic/GSorc) EDet is not at all worth it unless you feel you need a super expensive status symbol at that time.
9: Once you have an 8/8 in WC tops, go buy an amulet.
