What other units enjoy Mysthic Boost 3?

Well, Julius, Julia, Arvis, Saias, Deirdre, for anti-mage/dragons. Felicia for anti mage/dragon. Alm for his weapons refine since he can do it over and over. Some dancers like P!Olivia (any ranged dancer with high res really) who can now take on dragons.

However, most usability is ranged units with high res or the occasional unit who's weapon fucks their HP up a bit (Alm alone really) since that let's them multi task.

If you're asking what unit to use it on (if you have a spare copy) maybe a list of units you'd be okay using it would help.

If that isn't the question and it's just to know, well then around what I said. I gave a few good examples so you could probably work around that.

Edit: This synergizes best with ranged units that have high res but low def and are used to combat dragons. Also very useful for units that like to run Fury but have no need for a specific B Slot since Mystic Boost can and will replenish their HP to full (the -6 from Fury is negated by the +6 from Mystic B

My Lucius will thoroughly enjoy this skill whenever he gets it.

He's got 39 res at the moment, and fears no dragon (except one particular chicken). I've got atk/spd push in his a slot, which actually works better than many would expect - his native Martyr+ making the 100% hp requirement not difficult to achieve. When he gets this skill, though, he will never have to worry again. Dragons will only tickle him, and he can safely wear them down with Pain+. Now all I need is luck.

Anyone you'd put fury on, as well as any ranged units that have high res. Mythic Boost makes fury viable.
