sounds a little bit like
the spell. i made a weakaura for that when i got one, to use it the way i wanted.
basically involved waiting for the buff icon i wanted. so not realy RNG, just a lot of dev time spent on putting a huge amount of BS between you and the spell you want to use. or if its like seasons, then a bang-up copypasta job.
COOL, ITS THE FUTUUUUUURE!
