Reticence is Melia's fourth skill tree. It can be unlocked by completing the quest Trouble at the Lighthouse. This skill tree has a collection of arts that seem to better serve through skill links (such as bonuses to heavy equipment and "naked Dunban's" ideal addition when no gems are used). Prioritizing Reticence improves Melia's Ether Defence by up to 50 (5 if no skills are learnt).
