Morellonomicon TFT: How Does It Work?

Unfortunately, the Morellonomicon item in TFT (Teamfight Tactics) does not stack. So, if you put 2 or 3 Morellonomicons on the same champion, the burn damage and duration remain the same.

Also, if you have a Morellonomicon on 3 different ally champions that attack the same enemy champion, the burn effect on the enemy champion won’t stack. It caps at 20% of their max Health over 10 seconds.

To get Morellonomicon in TFT you need to combine Needlessly Large Rod + Giant’s Belt item Giant’s Belt. Morellonomicon is a Tier 2 TFT Item. It is best used against team compositions that rely on healing. It works best on mage and summoner champions like Zyra, Annie, Brand, and Syndra.

Morellonomicon adds +200 health and +20% ability power. Passive; Dealing damage with a Special Ability applies a burn on the enemies hit for 10 seconds, dealing 2% of target’s maximum health true damage each second and applying Grievous Wounds for the duration, reducing healing on the target.
