Unison Raid (合体魔法 Yunizon Reido) is an ability utilized by various Mages.
An extremely powerful ability that allows two Mages to unite two kinds of Magic similar in nature together, thereby creating an even stronger attack.According to Jellal Fernandes, many priests have wasted their entire lives trying to achieve Unison Raid without success, thus implying that it is an extremely difficult ability to master, or let alone obtain. However, Lucy Heartfilia and Juvia Lockser succeeded on their first attempt, as did Wendy Marvell.
