If you're wielding only a weapon without any shield you need to deal 1 blood hit every 30 hits. (60s)
If you're wielding a weapon and a shield with 1 monster attacking you, you have to deal 1 blood hit every 15 hits. (30s)
If you're wielding a weapon and a shield with 2 monsters attacking you, you must deal 1 blood hit every 10 hits .(20s)
If you won't meet those conditions your skill will "lock" and you will be no longer able to advance until next blood hit.
