So, you basically decided to build the best tank of the world as AP/Spell Vamp guy. While Spell Vamp is reduced by 2/3 because you do AoE damage. Plus AP Marks suck. Plus what the hell is the sense of this item image? "These are the items I use and an explanation of why:" First made me think you actually ever tried to build Muramana on Zac...

Overall: Euhm, Nope

I don't play Zac but I did enjoy the guide.

Don't take it the way I say "you have to" sure some people will run fairly well with either of those items and I even think some people will run him full ap and still be good with him because they know what they are doing in the game and play him better than I do.

But in "my" opinion and "my" logic tells me that it is more effective like I said. Personal preference tho~

Logarithm, yeah lol it is pretty bad. I checked out your guide and it was amazing man! I wish I knew how to do cool formatting like that! Anyways, if you have any tips for a noob build maker like me i'd love to hear it! Thanks!

link491, thanks for seeing the time I put in! Im pretty bad at formatting stuff so thanks for the positive feedback! Hope you enjoy the build!

Lampi, thanks for your positive feedback! I will take into consideration what you have said and apply it to my build in what ways I think would benefit it. I like the idea of magic pen runes and yes the picture of items was pretty stupid lol! I'll be sure to change that right away! Thx for the positive feed back!

alright, formatting wise, this gude is very well done, and i like that, as it's hard to find that kind of thing. the guide itself is satisfactory. it's obvious that you put quite a bit of thought into this guide, so im not gonna penalize you for it, but this is still not amazing.

Really don't like your build.

Zac is a tank and building much ap on him is wasted cuz his ratios are really bad and if you fall back with zac it's really really hard for coming back to game.
Dropt the liandris and spirit of spectral wrath and go more tanky.

if you want to "use" the spirit stone get the ancient golem spirit. It grants tenacity which you need since you go for mobility boots and it grants free armor and some usefull health and since he doesnt need the manareg and he really needs the hp it's wise to get the ancient golem spirit instead of the 50 ap which won't change much in the dmg calcs of Zac.

Rushing either the spirit visage which got good mres stats some usefull hp and the awesome passive for zacs passive it really fits zac. It's kinda personal preference if you want to go for the Wota instead maybe changing thoughts with your ap carry would be good most ap carrys will get wota later on tho.
Rushing either of those two (rushing the revolver not Wota of course) helps him out with sustain in the jungle.

After that going for a warmogs or sunfire cape or rylais is really good. Rushing a sunfire cape when the enemys are ad heavy is also a valid option but you'll need to get the revolver or the visage straight afterwards.
Rylais is powerfull too because it provides neccecary health and a "stick to your enemy" passive with Zac's W and R.

Abyssal is very usefull too since you always stick to the enemys and you have to initiate and proves mres too. I get it mostly after 2 tank items. So it's my fifth item in all.

At last I get something which fits the situation mostly a deathcap cuz it bouds up like 3-4% max health dmg with your W.
Going for more sustain or hp is valid too if your team has enough dmg but lacks the sustain.
Zac is really made for distracting and disturbing the enemy team with his reallllly intense cc power.
But if you are okay with the tankyness and if you survive mostly every teamfight I can go for straight and heavy ap. Deathcap suits here good tho.
If the enemys are really mres stacking I would even considering going more for a voidstaff than a liandris. Zac's W does such a significant dmg and it has to go through the enemy.

I consider for runes:

mpen marks - cuz you need the pen for the maxlife dmg which will be your main dmg with your R.
armor seals - armor for jungle sustain and...armor o.O
mres glyphs or armor glyphs - depending on the enemy team.
flat ap, mpen or ms quints - flat ap for the jungle dmg and some more gank dmg | mpen for making your W kinda impossible to resist | ms for sticking to your enemys even better even early on.


Also don't like the style of your guide...and...what is that pic of all items?! There are even S1 items in there o.O too big and mostly wrong just..fail at place tho~ use items which are viable for Zac instead.
You didn't used any spacers and didn't explained every choice of yours and you should link items like this ( Zac) and make little pictures for explaining things better etc. etc.

phew...wrote a bit much tho~
well - just my 2 cents~

It's oozing with terribad.

I love this build, works very well for me.
