Why is a clean elemental wand 7 more expensive than elemental wand 5/6 with the same stats? Even though EW7 gives luk which makes you miss out on the base int the other 2 provide? Or is this just in my head and EW7 is not more expensive.
Ewand 7 with the same TMA is worth more because of the lack of int. Ewand 7 also comes from CBD gach while the other 2 comes from shrine/nlc.
I guess it's because how common Ele5/6 are compared to to Ele7, plus the luk bonus can sometimes translate to higher level gear making it more valuable than int
Elemental wand 7 has a very, very high demand by Ice/Lightning Archmages, and not only that, the only way to get one is through CBD Gachapon. Elemental Wand 5 are slightly more expensive and more wanted then elemental wand 6 for the same reason, where fire/poison Archmages needs them!! If you're a bishop definately go for a Elemental Wand 6 because how much cheaper they are! Cost efficient! 5&6 as said by @resum are available at a very popular gachapon, therefore their lower prices. Luk is Quite a Ignored stats tbh, as a F/P or Bishop, that several int stats are better then wearing higher level equipment imo.
F/p gear is way cheaper than I/L as well. From mastery books to weapons/equipment. I think it's because there's not as many F/P, so the demand is low for their equipment. When it comes to bishops, f/p are about 90% less mesos as well. As for the wands, the ones that give element bonus damage to poison and lightning are the Arch Mages end game weapon. Those are their bossing wands. Until they have enough magic to 1 hit petris with those wands, they stick to the fire/ice bonus damage wands.
