Spreading your tentacles around the map is a good strategy. You can then use Harsh Lesson to command all tentacles within range to attack her target.
Use Leap of Faith when there are multiple enemies nearby so that you spawn the max number of tentacles. This can dramatically shift a teamfight because the tentacles deal a lot of damage.
Q: What is Illaoi's greatest strength?
A: Illaoi does great in teamfights. She deals a lot of AoE damage and heals based on the number of enemies hit. She is sometimes more unkillable in teamfights than in 1:1 engagements. She just needs to survive long enough between her tentacle strikes to heal back up again. Including some tank or other HP items in your Illaoi build will help her dominate team combat.
Q: What is Illaoi's greatest weakness?
A: Illaoi's damage and survivability depend on her having tentacles nearby. During the laning phase, these can be knocked out relatively easily by ranged champions. During the roaming phase of the game, she won't often stay long enough in one spot to build up enough tentacles to be terrifying. While her Ult will spawn additional tentacles for each nearby champion, it isn't a sure thing and has a long cooldown.
LoL Illaoi players could find her to be a complex champ to build out properly. You will find that her build varies when she is playing against either well-rounded or specialized team comps, indicating you should not follow the same Illaoi build every round of League of Legends
The most critical items to incorporate into your champion's build include: Iceborn Gauntlet, Sterak's Gage, and Hullbreaker. Players who added these items in their kits had a much better win rate than those who used other Illaoi builds. Moreover, if you are trying to beat a well-mixed enemy team composition, you should really consider grabbing her the Resolve, and Precision runes. In recent games, she won the greatest number of her games when built with these runes.
We established our Illaoi build guidance by examining 85,342 recently ranked LoL rounds with her selected. We only propose the highest winrate Illaoi builds that have been built by ranked League players enough times for us to propose them. With so many games in our dataset, we are very confident in our provided builds.
