well i was thinking poring hat could be (when slotted) +1% neutral def, and marin is for water, and so on for the poring family hats...
then the assorted hats could give small stat, status, or secondary attribute bonuses such as:
marina = 2% chance to freeze
wicked lily = 2% chance to SC (thought 1% was a better number, but since AFAIK ppl rarely hunt wicked nymphs, perhaps this could be a good incentive)
leaf cat = 2% chance to cast heaven's drive
wild rose = +1% Attack speed
hylozoist doll = 2% chance to curse
incubus and succubus is hard to get, but i kind of disagree with fates's notion as they should be in a pair like how their horns are...
so perhaps incubus would give 5% chance to cast lv 5 soul strike while succubus would give 5% chance to cast lv 5 napalm beat
