I am on the boss "Seymour Flux, Mortiorchis" and I just cant defeat him! He keeps casting Antropy and then Full-Life on me. I want to use RIkku's Customising feature to add Zombie Ward to my characters weapons, because I dont get time to use a Holy Water to heal Zombie in the fight, as he casts Full Life straight after. I need 20 Holy Waters to add Zombie Ward, and I have plenty, but it still wont let me add it to the weapon.
Anyone know what I'm doing wrong??
