the basics are: you want to keep your mana meter as balanced between black and white as you can (eventually you want to have them start being near but not equal but that's not until you hit like. 68)
-use verfire or verstone to get your dualcast active, then hit the opposite color long-cast spell on the free cast (so verfire > veraero, or verstone > verthunder), and then start again on verfire or veraero depending on which color of mana is lower
when you have enough black and white mana to do a full enchanted melee combo (80 of both if you're at 52+, or 55 if you're at 50) zoop in to do your melee combo
i mean i get the thing about keeping the mana levels even, i think there was something about it being harder to fill your dark levels if your light levels are too high, and vice versa
