Offlane. Malefice is a very good early game stun, use it to contest the first rune. Demonic Summoning lets you summon eidolons that multiply after landing 6 attacks. This is unbelievably good for pushing and farming, hold left click and drag your mouse over the eidolons to move them at once. The eidolons aren't strong enough to beat high level neutrals on their own, only send them to low level neutrals unless Enigma is also there to back them up. Black Hole is the most iconic ultimate in the game, it does massive damage, pulls people in and prevents them from moving. Be SURE to HOLD R to channel it! Ideally, use Midnight Pulse before Black Hole (mind your mana)
