this to find the spell for DW and now much they cost in set points. You get 1DW Tier every 8 points so right now you have DW3 + 4 wasted points. If you have at least 100JP, you get trait +1 as long as you have the trait active, while 1200JP gives you trait +2. Axexcennah is correct, once you get to 1200JP, you can set just 1DW trait (Delta Thrust+Barbed Crescent being the most point efficient, Molting Plumage being the most slot efficient) and cap DW with just
6DW in capped haste situation, easily achievable with Erratic Flutter + MG
