Fortify

This is one of those spells that is over looked.

I've seen this work very well with

The turret is protected, and it will attack harder. Getting the upgrade of this will help those tanks that have very little farming potential.

It takes a keen eye to know when to use this.

Fortify is underused, but it's good!
I love this, mostly when playing jungler(shen ftw).

I've seen a lot of Nunus get Fortify. It truly is an underused Spell, though.

Dose it's passive (+9dmg) aplayse to neutrals as well?

Good question! Does the 9 apply to neutral mobs? but also, does the 9 just apply to damage attacks, or is it spells also?

Yes the 9 dmg does work on neutrals as well becaus it says minnions and not enemy units. I have seen severel junglers use it as well.

Personaly fortify is my favorit spell. because even when you are low health u can use it to kill those nasty turret divers ^^ and save team mates from turret divers. and the 9dmg extra on minnions is always nice if you play tank ^^

Very underestimated. Works well with taunts and stuns. Also proventing those pesky backdoors.

I agree with Ternzilla, fortify is a very situational spell, and its cd is way to long, plus the spell is pretty weak without the mastery buff along with it

One thing that's often overlooked is that it can be activated while dead. It's worth having one copy on your team.
