To cast Riftwalk 10 times, you'd spend 5500 mana (100+200+...+1000). At level 18 you have 1050 max. With 6 x Rod of Ages, you'd have another 4350. With runes, another 800+. (6200+ total).

So it is possible with a build that gives you at least 5500 max mana. (Also, it would deal 5500+27.5*AP. You're effectively casting it 55 times).
