[TFT] Does Morello Stack in Teamfight Tactics? (Updated for Patch 9.20)

(Aug 29: Since TFT Patch 9.17, the Burn Effect (Grievous Wounds) doesn’t fully prevent healing, instead it reduces it by 80%.

Aug 14: This article has been updated to reflect Morello’s Burn duration increased to 10s in TFT Patch 9.16.

July 31: Patch 9.15B Update: Morello’s Burn damage has been reduced from 25% to 20%. You can read full TFT Patch 9.15B notes here.)

Morellonomicon is still considered a top tier item in TFT because of its versatility. It works great on multiple champions, both in early-game and late-game as well.

This brings up a question: Does Morello Stack in Teamfight Tactics? Let’s find out.

Does Morello Stack in Teamfight Tactics?

The short answer is NO, it doesn’t stack.

Even if you put 2 Morellos on a single champion, his ability would still burn the enemy units for 2% of their Max Health per second. Stacking Morellos won’t increase the burn damage % or the burn duration.

The only stats that stack, as with all items in TFT, are the stats from the basic items required to build the Morellonomicon. So stacking 2 Morellos would grant that unit 40% Spell Power and 400 Health, but that’s all.

Does Burn Damage Stack From 2 Morellos on 2 Different Champions?

This is the next question that comes up regarding Morello in Teamfight Tactics. Again, the answer here is NO, it doesn’t stack. Let look at an example:

  • So basically if you have a Morello on Lucian (yes, it works because his 2nd shot from his Ability deals Magic Damage) and one on Kha-Zix (it works on his as well, but it’s a sub-optimal use for the Morello).
  • If Lucian hits an enemy unit (let’s say Volibear) with his ability, Voli will take 2% Burn Damage per second from Morello over the next 10 seconds.
  • If after 3 seconds Kha’Zix with Morello uses his ability Taste Their Fear on Volibear, this will reset the Burn effect from Lucian, so he will now Burn for 2% of his Max health per second for another 10 seconds.
  • So Voli took 3 seconds Burn Damage for 2% Max Health per second from Lucian, plus another 10 seconds Burn Damage for 2% Max Health per second from Kha’Zix. This translates into a total Burn damage of 26% over 13 seconds.

How Does Morellonomicon work on Garen?

This is another popular question and it’s mostly because of how Garen’s Ability “Judgment” works. When his mana bar is full, he starts spinning for 4 seconds dealing Magic Damage to adjacent enemies. We explained in a different article that Morello does work on Garen, but here we’ll see how it works.

Since his ability takes 4 seconds, does it mean it stacks the Morello burn each time it hits the enemies?

No, it doesn’t work like this. It’s pretty much like the example above, where the last Ability that hits an enemy will reset the burn effect.

So when Garen with Morello starts spinning, this will immediately apply the Burn effect on the adjacent enemies, while also dealing his magic damage from spinning 40 / 65 / 90 per second (that’s why positioning Garen is very important in TFT).

Assuming the enemies are healthy and will leave for the entire duration of Garen’s Ulti, besides the Ulti damage, they will still have the Burn applied on them and for each second that Garen spins and damages them, he resets the Burn effect.

So after one second of spinning, the Burn effect will be reset again to burn 2% of Max Health for the next 10 seconds. And it will be like this until Garen finishes his ulti.

When he stops spinning after the 4 seconds duration of his Judgment ability, the Burn from Morello would have just been reset for the next 10 seconds.

This translates into the enemies having the Burn damage on them for 14 seconds, with 2% ox Max Health being lost per second, which means they would lose 28% of Max Health over 14 seconds.

See why Morello is great on Garen also? Well, the only problem is Garen also needs to be healthy to live long enough to fill his mana bar and channel the full Ability, but with some Health, Armor and the Knights bonus, this is achievable, especially early-game.

There are many champions which work great with Morello, like Kennen or Karthus, but we have a separate article covering this topic.

Does Morello Work on Graves?

This is another very popular question.

The short answer is: NO, it doesn’t proc the Burn effect. This is because Graves doesn’t have an Active Ability like most champs in TFT. His Ability is Passive and it makes him deal AOE damage with his auto-attack, instead of attacking a single unit. We get into more details about Graves and Morello in this article.

So while his auto-attacks don’t proc Morello’s Burn, they do proc Red Buff’s Burn to all targets they hit. This is why Red Buff works great on Graves, as we explained in this article.

Does Morello Work on Volibear?

No, Morello doesn’t work on Volibear. We explained in this article why it doesn’t. Basically, his ability is a basic-attack modifier, so he doesn’t use any spell, which is when Morello procs the Burn effect.

Morello on other Champions in TFT

We just looked at a few examples in this article. We’ll consider explaining how Morello works with all champions in TFT, but in a separate article.

What you need to know is that Morello procs the Burn effect for champions that have Active Abilities and that multiple Morellos don’t stack in Teamfight Tactics.
