So yeah my very first build so may not be perfect. I chose to do one on voli as he is my highest win rate and i always seem to wreck just buy going full tank

[Pro]
High Health and high damage resist
OP passive with low c/d
Good engage and okay disengage
W kills all squishies
Basically un-****ing-killable
[/Con]
Grevious wound hurts early
No escape apart from running fast
1 ability of High damage (W)

So i know what you're thinking "oh his runes are all over the shop" yes, yes they are BUT they have worked since i started them for my 'Tank' runes and they are yet to not do exactly that. Fair call as volibear mobility is vital but I find so is timing a gank aswell as timing your e and smite so they're that slow it doesn't matter. Better to be unkillable than to be fast enough to run away from a fight. But if it seems like you can't keep up then yes switch my quints for some movement quints

Pretty straight forward keystone. We want health and lots of it and seeing as we're building full tank thunderlords doesn't seem like a viable option as it scales off of Ad and Ap

So my core item's are Dead Mans plate (Health + a bundle of armor) aswell as its passive of bonus movement speed at full stacks. My second is boots of swiftness. With mobs been mobs it only take's an auto and you'll find yourself moving at the pace of an elderly woman hoping on one prosthetic leg and balancing that on a wooden one, short term you're slow once hit, swiftness with alacrity gives you enough movement speed with passive slow resist it's a win win situation.

Your role not only as voli but as any basic tank is to soak up damage and peel for your team i.e Protect carries under fire, get to enemy carries and spook em, flip em and grill em.
As voli you will most likely be your teams engage so you want to target the strongest carry and get him in a position where your team will hopefully act and long story short hes ****ed and there team is 1 carry less

Well i'm tired now but if i feel i want to add anything else to this build or tidy it up i will. Feedback is appreciated, Flame me and i will find you and i will kill you
