Coolest Magic Used by Fairy Tail Mages

When Gray got Ice Devil Slayer Magic, I fangirled so hard I felt like I was about to faint! He is even hotter in his devil slayer form! I didn't think he could get any hotter but I was so wrong! His powers are also really cool and I like that it makes his character even more interesting than before because he is the one who tells the guild Natsu is E.N.D. and a whole lot is going on with Gray right now and I am interested to see what happens in the last season!
