Be sure you have on all self buffs. Then bubble and run up a bit select a target a bit away from you then hit it with sandburst blast(and all in AoE range). Glacial shards next as they approach. Then, EV and AoE as CD lets off...they should be dead after 1 more sandb.b. Depending on which pv and what buffs you stack. Start killing sleepers from range and then repeat when chi fills....
