Maud strikes the base of Chrysalis’ horn  
“GAAH!!! W-what is this??? M-my magic!!! What have you done to me???”  
“I have just struck the vital pressure point that regulates the flow of your magic. But that’s not all the damage this attack has done… In a moment, you will feel an excruciating pain. Since you can no longer release your magic through your horn, it needs to find another way to get out… and excess magic will continue to build within you until…”  
“W-WHAT??? N-NO, PLEASE, I–AAAAAAAAAGH!!!”  
“Omae wa mou shindeiru…”

@MacDougal  
“ATATATATATATATATATATATATATATATATATATATATATATATATATATATATATATATA–WATAAAAAA!!!”  
HOKUTO HYAKURETSU KEN!!!  
“Omae wa mou shindeiru…”  
“NANI…?!”

@Cyborg_pony  
Atatatatata!

I honestly forgot about that, so I guess my earlier comment is flawed. Then again, one could consider that she still has amazing physical strength with or without her magic after working on a rock farm since childhood.
 
Kinda like in Bleach, after Ichigo lost his Shinigami powers after beating Aizen, and just managed to be in peak physical shape while beating some dudes up in the supposed epilogue (Seriously, I thought the series would’ve ended after Ichigo owned Aizen…)?

@Dirty Bit  
So like, it lets earth pony magic still work then?

Exactly! She would’ve crushed it to dust the moment she identified the rock and it’s magical properties. Then, she’d just go straight to Chrysalis while worfing any drone that crosses her path, save for Thorax.

Huh. If they’d brought Maud, they might have been able to destroy the throne without the massive love pulse.

Never, ever get on Maud’s bad side. It will end in pain. A lot of pain.
