Hm I was going to do pandaring but I can't beat the ones on the internets, think I will try masterdrops. Got a sketch up just have to somehow make it on the computer without it being crappy now.
As for effects, just going down the list my ideas would be,
Sapling > poison immunity on footgear
Pandaring > cause mass confusion in area when attacking, on weapon
Masterdrops > no effect, combo effect +4 luck with celebration wings on head
Autumn Leaf > cause great natures to drop on accessory
Aquaring > cast lvl 3 waterball when attacked on armor
Levia Lucha > cast lvl 10 waterball when attacked on armor
Hollow Poring > makes you size2 on accessory
Pumpkinring > I like that pumpkin effect said earlier
Midnight Jack > Cast undead when attacked on armor
Eye of Surtur > combo with cursed hand +3 aspd
Fafnir > -20% damage from dragon on head
Surtur > Cause Flame Hearts to drop on accessory
Selkie > Cause Mystic Frozen to drop on accessory
Eralia > Cause Icicles to spawn around when attacked, on accessory
