Sword of the Creator
When the move is used, Byleth extends the Sword of the Creator in its whip form, reaching up above him/her. Should he grab an opponent, he will pull himself up to them, and leap off them, meteor smashing them starting at 50%. It should be noted that the meteor smash is untechable. Its grab hitbox will also not work on shielding opponents, akin to Fishing Rod, Grappling Hook and Buster Wolf. This move acts as a tether recovery, and boasts quite a long range. He can also latch onto a wall, pulling himself up to and jumping off of it up to a maximum of 3 times.
The animation of the footstool has only one frame of ending lag, which can allow for combos into Areadbhar, or his Final Smash at percents below 50%, and his aerials at much higher percentages.
Alongside Areadbhar and Failnaught, the Sword of the Creator is one of the 14 Heroes' Relics in Three Houses, regalia weapons forged from the bones and hearts of the Nabateans by "those who slither in the dark". In this case, the Sword of the Creator was forged from the remains of Sothis. It was originally owned by Nemesis, the King of Liberation, who fought against Seiros and was killed in the encounter. The sword was taken back by Seiros and sealed away. One millennium later, Archbishop Rhea assigned Byleth to fend off an army led by the Western Church, who raided Seiros' tomb. They managed to unseal the Sword of the Creator from its hiding place and Byleth was able to utilize its power upon picking it up. After the battle, Rhea decided to entrust the sword to Byleth, which they keep for the remainder of the game. In a confrontation with "those who slither in the dark", Byleth got trapped in a dark void by Solon, and Sothis merged with Byleth to unlock the full power of the sword and free themselves.
The Sword of the Creator is a weapon that lets the user attack from 1-2 range. While the Sword of the Creator is in Byleth's possession, it grants them the Ruptured Heaven combat art, which adds some of the user's Magic to their damage output and is effective against dragon units. It can be wielded by other units as well, but they will not have access to Ruptured Heaven, and the sword itself will become much heavier and lose its ranged capabilities when used by anyone other than Byleth.
This move’s properties resemble the Grounder combat art, a sword attack that deals extra damage to flying units.
