1) For full redux, the mandatory gears are: Refined Deviling Hat / Laughing Poopoo Hat, Skull Aura, and any color of Sacred Wings.
2) Focus on AGI. As a full redux gypsy in WoE, your main job is to slow the breakers down.
3) Not sure what CK is, but Devi hat does not stack with:
[Vote] Forsaken King Shield
Friggs [Knight/King] Shield
Laughing Poopoo Hat
Also, a fun way to be hated as clown/gypsy is to break people's gears off. I've made an LK run from me in for_fild01 once by breaking his gear. LOL
