For the second trial, you'll need the two halves that make the Pendant of the Sea Lion.  One half draws power from the agility of the sea lion aspect, gliding through water; the other draws power from the incredible endurance of the sea lion aspect.  Druids draw on both these traits equally to embody the aspect of their aquatic form.$B$BSpeak with the locals of Moonglade to learn where the parts may lie, and bring both here to join them together.  Once formed, take the pendant to Dendrite Starblaze.
