Blocks Battering Ram

"Add, Limit Release Level One!"
"Ihihihihi!　I guess there's nothing else we can do, ihihihiihihihi!"
In my hands, the scythe dismantled itself, taking a form like a spinning Rubik's Cube. The raging magical energy within it took on a new form.
A battering ram.
Aside from Rhongomyniad itself, it was the form with the most destructive power.
As I brought the battering ram to bear, magical flames poured out from it. Translating into the terms used to describe the skills of Servants, my master had told me it reached a level similar to a D Rank in Mana Burst. Now, I slammed that full power down on Hephaestion.
As she blocked the strike, Hephaestion's sword groaned in protest.
"This, is-!" Her eyes were open wide. Even Hephaestion couldn't completely stop the power of the battering ram. Thus, it followed as a matter of course. The source giving birth to this Mana Burst was like a true Noble Phantasm.
