Marc's Premium certified Illaoi guide

Hi, my name's Marc, I'm an Illaoi main with over 100K mastery points. I play Illaoi for fun, though I do have a very respectable win rate of 85% on her. I'm a average mid-silver player and I don't play ranked often. I play on the NA server and frequently get flamed for playing an "easy champ".

Pros
High damage
Great team-fighting
1v5 Penta-kill potential
Very fun
High tank stats

Cons
Can be kited easily
You will often get flamed for playing an "easy champ"
Has some of the best counter-play in the game
Not the greatest early-game
No hard cc
No gap-closers

Passive- Prophet of an Elder God

Spawns Tentacles every 20-12 seconds on terrain that take 2 auto attacks to kill when Illaoi is within a certain range of them. One auto if she is far away from them. Your tentacles also heal 5% of your missing health for every hit on an enemy champion.

This is your bread and butter, when looking to fight, make sure you have at least 2 tentacles nearby. Also, once you get Black Cleaver your tentacles will be able to kill the back line of minions in one hit.

Tentacle Smash

Tentacle Smash summons a tentacle that smashes in the direction that the ability was cast. Tentacle Smash also has a passive that makes allof your tentacles do more damage.

This is your main harass and farming ability, it has a decent range and is pretty wide. Max this first.

Harsh Lesson

Harsh Lesson makes your next auto attack within the next 7 seconds gain bonus range and makes you leap to your target, doing bonus damage equal to 2-5% ( + 2% per 100 ad ) of your targets maximum health, capped at 300 against monsters. Any nearby tentacles will slam at your target. It is also an auto attack reset.

This is an ability that is underestimated. The damage on the auto attack isn't much, but the if you have more than 2 tentacles around you, you can do some insane damage.

Test of Spirit

Test of Spirit lets you pull out an enemies soul, any damage dealt to the soul will deal a percentage(25%-45% + 8% per 100 ad)of the damage to your target. If your target leaves the area which their soul is in, or the soul gets destroyed, then the target will have a passive on them which spawns a tentacle around them that will slam at them that lasts for 12 seconds. The soul lasts for 10 seconds and is decreased by 1 second for every instance of damage that the target does to Illaoi.

This can do insane amounts of damage if you hit both the soul and the target, as you'll be doing about 50% more damage to them per tentacle at max rank. It also counts as a champion for your ultimate. Upgrade this second.

Leap of Faith

Leap of Faith is Illaoi's ultimate, and boy, is it fun. Leap of Faith makes Illaoi leap in the air and slam her idol into the ground, dealing damage to all enemies in the radius. It spawns a tentacle for each champion and soul hit, makes tentacles slam 50% faster, and makes the cooldown of Harsh Lesson go down to 2 seconds.

This can let you pull of 1v5 plays with this, and you can 1-shot squishy champs with it too, especially if you pull out their soul. Upgrade this whenever you can.

When you're laning as Illaoi you want to get damage off without using up too much of your mana. By this, I mean you should use Tentacle Smash sparingly, as it can cost up to 60 mana.
Make sure that once you hit level 6, you should always have enough mana for a Test of Spirit, Leap of Faith, and multiple of Harsh Lesson.

Also, when you farm, use your Harsh Lesson as it costs less mana and does the same damage ( or more if you have more than 1 tentacle nearby ). Also, help yourself to the enemy blue, or ask your jungler for blue, as you need the mana.

As Illaoi you always want to get a good ult off. In team fights you should always be looking for a good opportunity to ult. If you have Flash, then you should Test of Spirit, Flash in, then Leap of Faith to get huge amounts of damage on the enemy team.

Thank you for checking out my Illaoi guide. It took me about 5 hours to do this, so I hoped you liked it. This is my first guide and I think I did decently. Well, thanks, hope you visit here again.
