May I know how to disable some spells to be sell in citizen shop ?
When I update wand with a new spells, player wand spells does not change and remain the same only change when they get a new wand, how can I fix this ?

Magic items such goggles, apprentice, wizardhat cannot set price in citizen integration shop, for example goggle it remain the same price even after I changed the worth and costs price

Magic plugin is awesome and extensive, I am using for a year but I still not fully understand about it configuration could you tell me a way to contact u as fast as possible such as email or facebook

General customization instructions are here:

Disabling spells involves adding something like this to your plugins/Magic/spells.yml:

blink:
  enabled: false

Configurations are just templates for new items. Once an item is created it is unrelated to the config. No way around that- get your configs right before you let players have wands.

The "magicitemshop", if you are using that, specifies prices directly in the shop config. See here:

https://github.com/elBukkit/MagicPlugin/blob/master/Magic/src/main/resources/defaults/spells/magicitemshop.yml

Just copy that to spells.yml and modify it to get the prices you want.
