wouldn't it be normal that all damage done by mage is increased by sun? well if you remove all your sun magic damage gears, your TW damage goes down, i tried adding in astral magic gears but that didn't add any damage, i'll test moon gears but there's no equipment that has both moon and sun so it's kinda pointless
a comparison between TW 5 and SS 5 would be nice, atm TW is a bit better, it is versatile - its an aim-able 3x3 aoe which you can even use defensively *cough*escaping*cough* compared to SS where you'll probably get hit before you can fire off one
