Personally, I think I'm leaning toward grailiing him to 120, but then I'd lose out on that juicy 20% NP gauge. So, what're the community's thoughts?

That if I could I'd replace "Emiya" in your name by "Oberon", which should let you know what I voted for :)

I chose "burn him" because I bet you, you won't.

Hard for me to fathom grailing him because I hate his character, but if he's one of your favorites I'd grail to 100 and unlock appends.

Please open his append skill. Maybe I can make something work with him with that extra NP charge.

Append. Also, thanks for reminding me to open the append on mine.

I unlocked his 2nd append skill for double koyan 3t farming using Black Grail.

I hate his character

You are difficult to understand unless you want to receive kindness from an anthoganist...

Out-edge the edgelord.

Burn him
