2001 post about t staff proc always lasting longer than 4-5 seconds to cast some spell
"the tranquil staff always stuns long enough to get a cast from the bio orb (4-5 seconds or so). As soon as the Tstaff procs, right-click bio orb and bang, unless he's got good resists, your opponent is blinded and helpless. "
i cant find anything that says 10 seconds every time but i cant recall it lasting 1-3 seconds ever.
