Rurouni Kenshin?

You obliviated Voldemort but Borgin still knows exactly who fought him and defeated him. If you don't take care of Borgin, you'll just end up having Voldemort attack your vulnerabilities.

Shiro's template is also very useful when it comes to learning magic. In DXD, magic relies on math. Shiro's brain is so ridiculously powerful that it makes the most powerful supercomputer in the world look like a graphing calculator.

Hou Yi's bow?

But dark magic can *literally* corrupt you, though? It's mentioned clearly in the books - in order to cast something like Crucio, you have to have a mindset of wanting to cause someone pain for the sake of causing them pain, not out of any righteous cause or rational reason. That kind of focused mindset would automatically be corrupting.

a thirtieth, not a third.

10% of 10% (aka 1%) compared to 30% (it mentions spiritual energy to qi). The math checks out. They'd be gaining qi 30X faster than him.

One of the worst examples of One Piece fanfics I've seen. I can't fathom how on earth this has such a high rating - the MC is a one-dimensional idiot who talks big and acts like a cliche Xianxia character, all the while he's too weak to do pretty much anything. It's like the kind of shit toddlers would cheer over. Massive derec.

5 reps for level 1, 20 reps for level 2, 5 reps after reaching level 2.

So ... Cradle cultivation? Wonder if he knew the Abidan ...

A quarter of Tien's strength is still WAY beyond Master Roshi's strength, though.

But Flitwick is more of a threat in combat than Snape and McGonaggal? After all, he's a dueling champion.

This is the actual, canon Dumbledore, rather than the Dumbledore you see in most fanfiction....
