Incapacitation

[Estellios]

I appreciate all the info guys.

His horn must have an insane amount of HP, because I spam Spirit's Within during the fight and it's never broken. :\

As was said earlier, but you may have missed it, Spirits within doesn't target Ifrit's Horns as its not classified as Head, its classified as Other (right) and Other (Left) on the charts above.

For Ifrit, as far as I know the only damage-able part are his horns. The body-part-looking-like-its-taking-damage might just be what the game does visually.

You can tell if you are damaging a part when the chat log says you are hitting it (ie: Your Concussive Blow hits the Young Raptor's head for 1000 damage.)

Sorry for bumping this, but as a DD job on Ifrit, I notice that my animations for my WS often hit a particular point on his body. Is this indicative of being able to incapacitate that part, or...?

Not at all. I mean, as stated above, you should get a message indicating you're actually hitting that part (i.e. Your [Weapon skill] hits the [mob]'s [body part] for X damage.).

if it says in the log, you hit a particular part, that means you can break it. if that's what you're asking

Ya know, I had been thinking of posting a thread regarding utilizing incaps (as well as the grey hp bar introduced in 1.18) to enhance existing/future content. It's sad when ALL raid bosses have add-on mobs that come to their aid as well as the Castrum Novum battle within the stronghold. Makes me really worry if all future content will be just as predictable as the last.

Could have nm's be completely invulnerable (adamantoise, anyone?) unless you incap them, etc...just so much potential not being used.
