Rod of Ages works over time, not per level. This is why buying one at 35 minutes is a complete waste. It takes ten minutes for it to charge to the maximum. If your game ends at 40 minutes then you wasted a lot of gold. This item, however, works based on level. You get 10 + 2*( your current level ) AD.

Sidenote: If you end up with a Catalyst at 25-30 minutes please just turn it into a Banshees. It isn't worth it to buy a RoA.
