Not getting any dark and light weapons from raids

[GAOtheGamer]

I have been hitting the foggy white castle for weeks and have not gotten a single dark and light weapon. It is primarily accessories and only a couple of weapons in between, all of which except one is water and the exception is fire. Do weapons have a lower drop rate or something and do light and dark weapons have a lower drop rate still for the weapons that do drop?

They do have a lower drop rate, if you go to shop and probabilities they have a Vita-Tau Equipment Box rates, it's 3.958% for elemental weapon, and .313% for LD, 12.5% for sub weapon and 6.25% for accessories, of course that's divided between purple and red at equal rates, and who knows if it's the same for the boss or token shop. I still am using a ♥♥♥♥♥♥ 5* dark purple hammer, and have had no light drops until I started doing Seal, and now it's given me 3 light hammers last week, 2 from drop and 1 from token, but you know after I already wasted all my materials to upgrade the first to the same thing that came from token, while not giving me any materials for the week.
