What exactly counts as immobilize?

[sg-ahri-1]

Google "immobilize".

Suppression, root, stun and now sleep (and amumu ult, even though it technically doesn't say enemies are stunned/rooted), also all knockups/displacements too all count as immobilize, something like lulu polymorph does not count because even though you can't use abilities/summoners you can still move (slowly).

Things that stop you from moving

I did google it, and found all sorts of random info... but ty.

Anything that prevents movement from one spot.

Roots, stuns, knockups, and entangle should be all of them.

Basically I was curious if a slow counted.

I tested it.

Slows don't count.

Taunt?

Would be op on Gnar if slow counted as immobilize :D

What about channeling something ? Would that makes you immobilized ? for exemple malz (himself) when he is ulting someone ? or just an ally spell "immobilizing" you

Fear is immobillizing too apperently
