How does chill duration work with multiple sources applied? Lets say I'm in Normal difficulty and hit a monster with a slvl 13 Frozen Orb, which has a chill duration of 20 seconds. Then, my merc gets hit and a ctc slvl 4 Frost Nova with 11 second chill length triggers and hits the same monster. How long will the chill be? Does it get added for 31, ignored and left at 20, or (worst case) replaced by the 11?
