How Magic Works (by Centurii-chan)

You can also interrupt a cast by preventing the caster from providing one of the components of the spell

Funnily enough, in D&D 5E that wizard explicitly can cast that spell (if you're equating Power Word Kill to Avada Kedavra)

Maybe not directly related, but this talk makes to me a very compelling point about how magic should work in satisfying fiction.

"The Last Unicorn" has magic that works this way, and it's pretty good.

I feel like this is true if the reader is meant to have the perspective of the person who feels that something is magic (the Hobbits, in the example from your video). However, not all magic in fiction is like this, and sometimes the reader is supposed to mostly have the perspective of Galadriel, or to gain her perspective over time.

An example is Lev Grossman's The Magicians. The reader has the perspective of the Hobbits at first, because that is the perspective of the main character. But the story has themes of "lifting the veil" of magic, and by the end both the main character and the reader have a more similar perspective to Galadriel.

I guess what I mean is, I agree with you and the video's author in large part... but like... to broadly say that magic "should" be used in literature in a certain way ignores how it can be used in different ways to great effect!
- what's the perspective of Galadriel??
Sure, but in a ttrpg you need a system or spell casting classes will dominate too much

Caster: Ow fuck. I can't believe you've done this!

Why does it have blue hair? I don't think hair dye exists in a medieval world, or at least and easily accessible one

It isn't a medieval world though.

It is a fantasy world that merely resembles medieval Europe. You can see this in the way she cast freaking magic.

And even back then people dyed their hairs, yes including blue.
Hair dye actually has a long history.

Magik
Magic? Nothing to blink twice at!

Hair color that's fun for the player? Realism ruined.
- It's so funny when people get caught up with things like that.
  
  It's also funny but a little sad when people's expectations of how colorful ancient times ought to be, or rather shouldn't be, create standards of "realism" that are completely opposite to how history really was.
Hair dye DID exist in medieval times tho, and in fact, even ancient Egyptians dyed their hair
Why is the LITERAL WIZARD not a tradwife lmao
blue hair = 5*5+10+10*5*5*10

Have fun!
