There are two strategies to choose from for this mission. One involves defeating the Brittle Rocks with DoT, and the other relies on defeating Qirirns to obtain Qiqirn Mines to detonate the rocks. Note: If using the DoT strategy, make sure that against the first Brittle Rock, anyone casting is right up against the rock to avoid the possibility of bomb aggro. Note: This assault is a lot harder on uncapped when compared 60 capped as I have experienced for example 2 Doter(BLM or RDM/BLM or DRK/BLM) and 2 melee DD can win 60 cap with 5-6 mins to spare were as in uncapped they may struggle if you don't have the right melee DD.(imo this is because the melee DD the party does not increase (DoT is fixed as well) as the walls HP does in the different caps)
