It's not a rule to have it. People have it because it's necessary for RNG manipulation.

Makes sense, I x speed on archie though not true double, just a guard spec/x special there? Think you outspeed regardless there unless somehow scary face hits after your guard spec? Hopefully next time I wont get so unlucky that I get RT twice haha.

Lost 2 minutes on my PB the other day due to getting speed dropped on Drake. Kept getting paralyzed/damaged by dragonbreath and wasting lots of turns healing. Any advice on how to play this fight when you get turn 1 rock tomb speed dropped?
