Aphelios isn't that hard to master (Tips)
I bought the new champion,
Aphelios, and it just took me like 6-10 minutes of mastering him in Practice tool. I didn't even read his skills that often, but it just takes some good hand work.
But i think that the best damage weapon(s) (for me or for anyone) is Severum, the Scythe Pistol (Main Hand) and Crescendum, the Chakram (Off Hand)
But i also recommend Infernum, the Flame Thrower (Main Hand) and Calibrum, the Sniper Rifle (Off Hand)
Gravitum, the Gravity Cannon is the only one that doesn't use it's Off Hand Passive on his Active Skill.
But apparently, any kind of weapon (Main hand and/or Off hand) still deals tons of damage. So just look for some perfect weapon combos for you.
