Hallowvrybuddy, Foo here. Making another strategy post!



I was playing a game as ADC earlier, and I saw that my AP carry ( Orianna) had built Morrelo's Evil Tome Morellonomicon. I immediately facepalmed and thought to myself "What a scrub."

I then stopped myself and thought: "Wait, have I ever even given it a chance? I consider myself very open to unconventional strategies, and maybe Morellonomicon is actually a decent item." So, let's take a look at the math. (NOTE: I wrote this litte bit before I started doing the math, so I have no idea how it will go as I am writing this)


Math



Morellonomicon:

Total Cost: 2200g

AP: 75
Gold value: 1575

MP5: 12
Gold value: 720

CDR: 20%
Gold Value: 660

Passive: Dealing magic damage to an enemy champion below 40% health inflicts Grievous Wounds to them for 4 seconds.
Gold value: N/A

Total gold value: 2955


Now, let's compare it to a similar AP item.

Athene's Unholy Grail:

Total Cost: 2800

AP: 60
Gold value: 1260

MP5: 15
Gold value: 900

CDR: 15%
Gold value: 495

MR: 40
Gold value: 790

Passive: Restores 12% of your max mana on kill or assist.
Increases your mana regeneration by 1% per 1% mana you are missing.
Gold Value: N/A

Total gold value: 3445



Now, to compare them both, let's look at how much bang you get for each buck.

Morellonomicon: 1.34 gold worth of stats for every 1 gold.
Athene's Unholy Grail: 1.23 worth of stats for every 1 gold.

/end math

NOTE: I approximated the gold values a little bit, since it changes with every basic item. All this was assuming that:

AP: 21 gold per 1 AP
MP5: 60 gold per 1 MP5
CDR: 33 gold per 1% CDR
MR: 19 gold per 1 MR



Math Conclusion



So, there's a lot to be said for this. On paper, Morellonomicon is actually the more cost effective of the two. However, we cannot take the unique passives into account. Magic regen is the one of the most costly stats, and the unique passive on Athene's Unholy Grail can up to double your MP5. However, you are paying an arm and a leg for mostly mana regen.

The only thing that can really be gained from all this math is this: Morellonomicon is a remarkably cost effective item.


What are you paying for?



Morellonomicon vs. Athene's Unholy Grail:

AP: This is actually remarkable. Morellonomicon actually gives you the most AP per gold of any (non-basic) item in the game, other than Rabadon's Deathcap and Hextech Revolver. With a whopping .72 gold worth in AP per gold spent. It actually beats Rabadon's Deathcap if you don't count the 25% bonus AP.

MP5: The mana regen is a big part of Morellonomicon. If you don't need any more mana, this item should not be purchased.

For Athene's Unholy Grail, MP5 is what you are paying the big bucks for. It gives, by far, the most mana regen out of any item in the game. If you REALLY need the mana, this is your go-to item. However, most mages don't need that much. If you aren't using all of the mana regen, you are wasting a LOT of gold.

CDR: Morellonomicon gives more CDR than Athene's Unholy Grail. Nothing more to say about that, really.

MR: Magic resist is only given on Athene's Unholy Grail, so if you need MR, this item is great. However, most AP carries do not need magic resist. Basically, the MR just makes this a more situational item. You spend a lot of money on the MR, so you don't want it unless you are taking magic damage.


Unique Passives:
Morellonomicon's passive is very situational. If you are against a Dr. Mundo it will be phenomenal. However, the healing debuff usually won't be all that useful. However, it can still be quite effective against certain tanks, like Maokai and AD carries if you manage to apply it to them.

Keep in mind that this passive procs on basic attacks if you have Spellsword .

Athene's Unholy Grail's unique passives are much stronger in most cases. However, the mana return on kills and assists won't be useful unless you are someone like Swain. The "mana font" passive also won't be worth much unless you are really mana hungry, like Anivia.


Components in Lane Phase



Kage's lucky pick: A Gp10 item can be useful, but honestly isn't that great. This item is very cost inefficient, and the GP10 isn't very useful on mid laners, since they usually depend on mid game, and get the most CS anyway.

Chalice of Harmony: This is a MAJOR selling point. This item is incredible on certain mid laners. It is just the perfect lane phase item against another AP champion. Some champions really need the mana regen, and the passive is just broken as hell. It scales off of Mana Potions, blue buff and level ups when you have Catalyst the Protector.

However, a lot of AD champions have been laning mid lately. That makes the magic resist on this item useless.


Verdict:


Well, I have presented all the evidence I can think of for both sides. I have compared the math, the different purposes of the two items, and what their components are useful for. However, I still cannot give a verdict.

After doing this, all I can say it this.

Morellonomicon is an underrated item, for sure.
