Cyclone Strike is very useful for grouping up mobs.Although that being said, monsters spawn with enough density for at least 10 in most areas of the map. If you haven't gotten at least one by that stage, I recommend restarting the dungeon. The way I approached this particular Set Dungeon was to make sure at least 1 or 2 of the Unleash Mystic Ally objective requirements were completed within the 30 seconds or so.Cyclone Strike is the key to grouping 10 monsters, which I feel is a bit low compared to some of the other Set Dungeon objectives, but on this map tileset its hard to gather mobs I guess. The way I've tackled it above is to gear up for as much Cooldown Reduction/Spirit Generation/Resource Cost Reduction as possible, with Cooldown Reduction being the highest priority so you can Mystic Ally as much as possible. The Innas Set Dungeon seemed to be quite simple, and I think I overgeared too much for this. You can find general Set Dungeon information and Set Dungeon guides for the other classes at my Set Dungeon Thread. Reduces the number of items needed for set bonuses by 1 (to a minimum of 2). When Dashing Strike hits an enemy more than 30–35 yards away, its Charge cost is refunded.
