Pure Spawn of Hydross

Pure Spawn of Hydross can be found in Serpentshrine Cavern and Coilfang Reservoir.

General
When Hydross the Unstable changes to his Pure form, he will spawn 4 Pure Spawn of Hydross, which you can Banish. Note:Pure Spawn of Hydross are water elementals, which means you can't use frost trap/frost nova to CC. Kill these adds as fast as possible, you only have one minute before you will need to change Hydross the Unstable's vulnerability again. Make sure you don't banish too many of them or you will have to wait before you can kill them.
