You should use a variable for the spell id.
Please use a prefix for your variable, which should use between 2-3 characters.
This important in public resources to avoid code conflicts, when importing a spell.
Example: DR_Damage, DR_Duration, DR_Art ...
The way you handle MUI is simple, but not very efficient. Also it requires the use of an
hashtable. I would recommend a simple allocation module for this spell.

It's a well illustrated tutorial and easy to understand.
Simple, but useful concept, but the spell requires some work before beeing approve-able.
I also have to scan our database, if an equal spell already exists there.
I can't check the testmap today. :/
