The relationship between champions and manna is one of extremes. On one side of the fence there are manaless champions that may use health to power their abilities or simply be cool-down based. On the other side of we have champions whose intensive use of manna can deplete their mana pool in seconds.
The latter are the champions that will benefit the most from items that provide manna regeneration (Mp5). There truly aren’t that many champions that consume manna in vast quantities but Anivia, Swain, Karthus and Kassadin have ultimates that truly demand it.
The following table contains all items that provide a Mp5 bonus with their associated cost effectiveness: the cost of each unit of Mp5. The table can be sorted and by clicking on the last header we can see what cost effectiveness reveals.
|Archangel’s Staff||25||+400 Mana, +45 AP, Passive: 3% of your maximum manna is converted to AP. UNIQUE Passive: each time your champion uses an ability their maximum manna will increase by 4 manna. This effect has a 3 sec. CD. Bonus caps at 1000 manna||2855||114|

Basic items are often the most cost effective and such is the case of Mp5. Other items that are usually effective are Doran’s items. In this case Doran’s Shield is relatively effective but there are certainly better options.
It’s interesting to note that Eleisa’s Miracle is quite effective and a net improvement over Philosopher’s Stone. The same happens with Tear of the Goddess and Archangel’s Staff, the latter being a definite enhancement over the former.
Chalice of Harmony stand between both, depending on mana use its passive can help keep certain abilites on for far longer. However it completely depends on the mana regeneration available. Without a good bonus it won’t provide much of a difference yet it does prove quite cost effective.
A classic item for ability based carries is Manamune. It’s mana bonus may be a welcome addition but in terms of mana regeneration Manamune leaves much to be desired. It doesn’t even improve the Mp5 bonus from Tear of the Goddess so it’s the other bonuses that we end up paying for. Furthermore, Tiamat certainly doesn’t look like an alternative either.
Defensive items like Shurelya’s Reverie and Soul Shroud aren’t the most cost effective. Still, they do provide a reasonable bonus as long as mana regeneration isn’t a prime concern. In such a case a tank may be better off buying a Philosopher’s Stone or Eleisa’s Miracle and getting Mp5 for less than half the cost.
Finally, there are a few items with ability power bonuses that boost Mp5. Morello’s Evil Tome, Deathfire Grasp, Nashor’s Tooth and their little brother the Fiendish Codex grant small bonuses and have their total cost dominated by the other bonuses. They can help to mitigate increasing mana demands but are far from a real solution. Mana intensive mages should rely on Archangel’s Staff and consider these other items as supplements.
In conclusion, all types of champions can benefit from mana regeneration. Mages, support and tanks have an easier time adapting their build to boost Mp5 than carries. Notwithstanding, carries mana needs are much lower than other champions. Mages are probably the ones that benefit the most from mana regeneration and Archangel’s Staff stands firm as a good solution.
