Doubts with commands on NPCs

[Israel]

Hello guys from the forum so I have 2 doubts who can help me thank you from my heart '-'

1-Doubt I have an item on my server that when equipping it changes the colors of the character, but when this item is removed, the character looks like the beginning of the game. I would like to know what command I put on the item so that when item is removed it goes back to appearances, which was before equipping the item.

 

2- Doubt I have an item enchanter on my server I would like to know what command I place so that once the item is enchanted the enchantment is not removed.

 Thanks..............

1.

save the current appearance data into a variable

then change the appearance to new appearance based on item

when unequipped, load the appearance from the stored variable data

 

2.

retrieve and store existing cards or enchantment into a temporary variable, then use script command items like getitem2, getitem3....etc to create the new items along with old and new enchantments
