Early in the anime, Lucy asked Natsu if he could eat his own fire. Natsu
explained that it would be like Lucy eating one of her Celestial Spirits.
While this tells us that Natsu won't do it, it leaves the possibility open.

Given how Angel treated her spirits, I could imagine a more evil wizard being
willing to eat their spirit if desperate enough. So, could a more evil dragon
slayer eat their own magic? Would it make them more powerful or just back to
the state they were in prior to casting the spell?

Can Dragonslayers eat their own magic?


I think they can, but they just wouldn't gain any energy like they would from
other sources, so it's just completely pointless. There have been points with
dragonslayers in pretty tight pinches, and I'm pretty sure one of them would
have at some point eaten their own magic if there were any point in doing so/
if it's even possible.

I think Natsu was just making a bit of a stupid analogy when he said it was
like Lucy eating celestial spirits, at no point has there been any suggestion
that a dragonslayer's element is in some way alive, and he's more than happy
to fire off bursts of fire that presumably must burn out eventually, I don't
think ethics come into it at all, just practicality.

I might get a bit technical here, forgive.

My claim is that they can but will not consume their own magic because it is
pointless.

Consider the mage as an entity of energy. With the dragon slayers, when they
consume their element, they get a boost in energy which they use to fight
(Gajeel consuming steel, Wendy consuming air, ...and so on). I presume they
are using these elementals to top up on their depleted energy of to give them
a boost.

If they were to eat their own magic, it will give them a boost but it would
only return them to the level of energy they had before they produced that bit
of magic. They see no gain in doing such. To produce magic, they have to use
some energy. This energy has been converted from them into the elemental. When
they consume it, it goes back into them. Arithmetically, `x - 1 = x'` where
`x` is the amount of energy they originally have and `x'` is the amount of
energy they have after producing the magic. Consuming the magic they produce
will be `x' + 1 = x` which merely returns them to the starting point.

In the case of consuming their element which they did not produce,
arithmetically, that would be `x + 1 = x*`, where `x` remains as above and
`x*` is the augmented energy level. This augmentation is made possible because
this energy did not originally reside in them.

So yes, they can eat their own magic but it would be pointless

Well he can but he just chooses not to because he is uncomfortable doing it
but if it's absolutely necessary he will.

**They can't eat their own magic.** It was only recent (in chapter 391) that
Silver reminded us of this during his fight with Gray.

We saw a flashback of Natsu saying he can't eat his own flames.

Then two panels later, Silver confirmed this by blocking Gray's attack, using
Silver's magic, instead of eating the ice as he did before. As Natsu has,
Silver then mentioned he can not eat his own magic.

To be honest it doesn't make sense that they are physically incapable of
eating their magic, but if they could Silver would have been able to eat
Gray's attack instead of having to block. I guess Natsu being Natsu made an
incorrect analogy, back in chapter 5.
