Hey everyone,
Does anyone knows what modifications I have to do in order to make the support item square appear when using blessed enchants?
I tried to search for quite a while now accross the code without success, I hope its not client sided

I'm talking about this square that appears when using a normal scroll to enchant an item between +3 to +9:


I want to make it appear with blessed scrolls too:

nvm, this is client sided, the easiest workaround for (without touching client) it is to send the packet with an id of the normal enchant scroll version of the blessed scroll used.
