Predecessor Builds > GRIM.exe > Grim mid mage

I get hate for this build but it works and more times than not I carried. This build will have your ult doing 1200+ damage NOT including the additional damage from magic power. Combine a hit with displacement orb to get bonus damage from his passive you will delete carries and midlanes alike in 2 abilities provided they have 80% health or less. The 4th and 6th items and can be interchanged. Midlaners you’ll struggle with (because they take more skill to beat if they’re not trash) Bélica, Howi, Argus, and potentially Countess. Get good with Grims kit and playstyle you can crap on them too. In my opinion Grims dominance comes from his ability to poke with his lobs and his ability to BLOCK abilities if timed right.
