Muramana (WITHOUT ANY OTHER MANA ITEMS) gives her ult up to 144.24 extra PHYSICAL (meaning it'd now be MIXED) damage PER BALL and increases her AD, which makes her (VERY SLIGHTLY) less useless when OOM or everything's on CD somehow. An amount of AP EXACTLY equal to Manamune's cost (115.2) gives her entire kit 213.12 + 23.04 per ball magic damage. However, there is not an exact analogue to Muramana's damage as AP per gold spent. The closest we have to its COST, even, is RoA, which you would probably buy anyway (increasing Muramana's damage even MORE)/definitely would if not testing builds. It, at max stacks, gives 100 AP for 200 more cost. That gives 185 + 20 per ball magic damage to her entire kit.

So, mathematically, Muramana isn't terrible, as it gives almost as much damage as the closest priced AP item at 200 less cost, makes her damage MIXED (which makes it harder to itemize against), and makes her last-hitting easier without spells, but makes it harder with spells.
