General

1. Playing Rod of Ages Kassadin, your default rush is of course - Rod of Ages. You want to stack its passive as early as possible.
2. Rod of Ages gives sustain with its second Passive. It recovers both health and mana.
3. You can play this build very safely. Sustain from Rod of Ages alone is very powerful in ARAM. If you want to sustain even harder, you can get Kaenic Rookern (anti poke), Spirit Visage (more sustain) or even get Second Wind rune from Resolve.
4. In cases, when an enemy team is full of tanks and HP stackers and you need to counter them, go Liandry's Torment.
5. Adapt to an enemy team. They full of tanks and they rush MR? You rush Void Staff as #2 or #3 item. Their team is Soraka, Mundo or champs with healing? Rush Oblivion Orb as #2 item (upgrade to Morellonomicon as 4th or 5th item). They stack HP? You buy Liandry's Torment.
6. Somebody is going after you each fight? Their assassins are focusing you on sight? Always getting R by Fizz? Rush Zhonya's Hourglass.
7. Good MR item that works well with Rod of Ages is Spirit Visage and Kaenic Rookern.
