Tarmiel's Grace of Ocean creates a literal ocean to trap his opponents. This ocean appears to be a plane cut off from the regular world and is inescapable. This ocean is described as the domain of the gods, a space created by the Graces. This dimension is inescapable for those who do not have a power level equal to or greater than that of roughly a single archangel. Additionally, Tarmiel's Grace allows him to liquefy his body in order to escape his enemies or render physical attacks as ineffective. He has also shown the ability to summon the very water from this plane, using it to attack his opponents.

Enlil no Tenbatsu「エンリルの天罰, Enriru no Tenbatsu; literally meaning "Enlil's Divine Punishment"」: Tarmiel and Sariel combine their Graces to create a huge lightning bolt that falls on their opponent between the ocean and a tornado.
