Awesome! I just checked it out and it works. Thanks for the help.
I did some testing with Priority and it doesn't seem to have any effect on the overriding of buffs. The skills just replaced each other.
I just created two identical skills with slightly different stats, and different Priorities. So further testing could prove otherwise. I haven't looked at the relationship between different Strength Potions and how they override each other to see if it can be done at all.
