Not much more I want to add than what is in the title, but Zz'Rot's active sounds better to be a summoner spell since it is something based on what the enemy team has at the start of the game, but is a terrible item over all (never buy it unless you want to have fun in normals or URF or something).
joebobby14123 votesIt's a pretty great item. 60 armour is a lot and 60 magic resist is a lot. Plus, it does a great job on outer towers, but admittedly is nearly worthless once you get down to just inhib towers.
I like it as a second item on a lot of supports. Let's say you are Braum. Face of the mountain -> ZZ'rot portal -> righteous glory. Bam! you are tanky af, have a shield for you carry, engage for your team, and lane pressure even when you aren't there.
Late game, sure, swap it out for something else if you think you need to itemize more directly against their team, but as a general build ^that right there is amazing.
Stacona1 votesThe item is too extremely situational, you can only use it when winning, against certain comps, and even then other items are better and help you win harder
Masked Lunatic1 votesIts a stat boost plus it gives mobility around turrets making your tower dives a bit easier or allowing you to evade while under turret + when chasing it's useful. It can also be used as a good roaming tool place it behind your turret and it'll push while you gank other lanes.
I use it when i need the mobility to dodge skillshots plus defence boost (tank ekko works so nicely with this as a secondary buy).
Not to mention the item gives both mr and armor which is rather unusual for a single item (if not the only? - not sure on that so correct me if im wrong).
But yeah zz'rot gets overlooked most of the time... I admit i forget it exists most of the time.
joebobby14122 votesGuardian Angel also gives Armour and MR, it gives 50 of each.
Masked Lunatic1 votesYeah i couldn't recall it ty
AMYS GRAVE2 votesoh my no, i buy that item when we are behind. You drop your portal in the jungle near bot and it pushes lane for you (you get the gold from the cs it gets btw) and when it bounces off the enemy tower it pushes the wave back in again. I've taken turrets by just leaving my portal in that lane while I'm with the team defending mid.
LordGeovanni1 votesthats really what you do with it if its not working it just means that the enemy is aware of the map and your team isnt ready (i dont want to say smart enough) to defend the advantage they have. cant say it isnt advantageous cause its so disadvantagous to the enemy that the enemy is trying to do something about it
AMYS GRAVE2 votesWell the other thing you can do with it that is pretty effective is split push up to the enemy tower, and drop it just a bit outside turret range. It helps you take towers unexpectedly fast, and if it is defended by one person you can just repeatedly push the wave into their tower and watch the zz minions destroy it for you.
LordGeovanni1 votesthe passive and stats are always good and you can always use zz rots weather to defend a tower attack an enemy or break a seige its just that many people lay down the zz rots and then abandon it
