Gold efficiency = stat value ÷ item cost = 3183 ÷ 2850 = 112%. The gold per point comes from basic items of the same patch (for example, Long Sword: 35 g per Attack Damage). Passives and actives are not counted.

Morellonomicon is a 2,850 gold Ability Power item in League of Legends and the mage answer to healing: 75 Ability Power, 350 Health and 15 Ability Haste in patch 26.21. Its passive applies 40% Grievous Wounds for 3 seconds whenever you deal magic damage to a champion.
What does Grievous Wounds do?
It cuts healing. A champion hit by Wounds receives less healing and regeneration from every source while the debuff lasts: Life Steal, Omnivamp, healing abilities, potions, even an ally’s heal. Morello’s version is 40% for 3 seconds, refreshed every time your magic damage lands.
Why does that matter so much? Some champions win fights by out-healing the damage you deal. Drain tanks, fighters with Omnivamp, supports that heal the whole team. Without Wounds, your damage just gets erased (you can watch a health bar refill in real time, which is not fun). With it, every hit sticks.
The catch is that it only triggers on magic damage. Champions that deal physical damage need a different source, such as Thornmail for tanks or one of the Attack Damage anti-heal items.
Is Morellonomicon gold efficient?
Comfortably, at 112%. It hands you 3,183 gold of stats for 2,850 gold, so the Grievous Wounds passive is a free extra.
Split up: 75 Ability Power is 1,500 gold at the Amplifying Tome rate of 20 per point, 350 Health is 933 gold at 2.67 per point, and 15 Ability Haste adds 750 gold at 50 per point. Health on a mage item helps a lot in lane. To be fair, the raw Ability Power is modest for the price compared with pure damage items, and that’s the trade for the passive and the Health.
What does it build from?
Oblivion Orb (800 gold), Blasting Wand (850) and Kindlegem (800), with a 400 gold combine. Oblivion Orb carries the Grievous Wounds effect already. That’s the useful part: buy it early when the enemy has a healer, and finish the full item later. Kindlegem is shared with Hextech Rocketbelt, another mage item with Health.
How has Morello changed over the patches?
It’s an old item, in Riot’s data since 2013 or earlier, and it has been a Mana item, a cooldown item, a Magic Penetration item and now a Health item. The latest steps:
- Patch 13.3: cost 2,500 → 3,000 gold, Health 300 → 200, Magic Penetration 10 added.
- Patch 14.1: cost 3,000 → 2,200 gold.
- Patch 14.19: cost 2,200 → 2,950 gold, Ability Power 90 → 75, Health 350 added.
- 25.10 cut the price to 2,850 gold.
Patch 14.19 was the big one, adding Health and a much higher price at once. Funny enough, back in patch 6.9 it gave 400 Mana. Everything else is in the table above (it goes back years), and for other mage items our LoL items database has matching records.
Who should buy Morellonomicon?
Any Ability Power champion facing a healer. Mages in mid lane, Ability Power supports and junglers all qualify. Usually one player per team takes anti-heal, so check whether a teammate already has it before you buy (two sources of Grievous Wounds don’t stack into a bigger cut). A support with an Ability Power build can pick it up too, which frees the mid laner to buy pure damage, and on a team with no other magic damage the job falls on whoever has the most spells landing on the enemy healer every fight.
Honestly, timing matters more than anything. Is the enemy healing through your damage in lane already? Rush Oblivion Orb and finish later. If the healing only shows up in team fights, Morellonomicon fits as the second or third item. Our guide to LoL roles explains who usually carries the anti-heal job.
