Brimestone forces Magic Keep boss to not put up shields
Thought I should just say it in case people didn't know this and can make use of it.
so long as brimstone is up, she just kept using her standard attack, refusing to use the move to put the shield up. This has happened 5 different times now, which has helped a lot doing a solo carry to level food.
also noticing some champions refuse to use certain skills so long as brimstone is up like enemy Apothecary won't use the speed boost.
so, not sure how common this knowledge is.
