Enchanter Archaic: Vapor Trance Question

[esher2]

After looking at overpowering calm tome(which gives 15/30/45/60% less duration mitigation) I was wondering if this spell has a hidden duration mitigation effect to it? Or is it just the lowered cast time/mana cost/3 min duration?

Got a few different responses in game and not sure. (Don't have this spell yet, just curious)

Thanks

The increased duration is effectively mitigation as compared to other mez spells. Mobs will mitigate a random number of ticks off of a mez or charm, so the longer duration makes it more reliable.
