This is my first guide, so please do not expect it to be the most amazing guide ever, but just some tips and pointers about playing Tank Garen, And my Playstyle For him. In the comment section, please post some constructive critisism, since I am sure this guide will not start off very great, but make use of what is here!

The reason I have all health runes is because with all of that Health, very early game you are very durable, and if you want some health regen, armor, or magic resist, just replace some runes with ones that fit your playstyle. But I enjoy health, because if you get targeted in the gank, you can soak up damage for your team to get an early kill. You will also have pretty decent survivability early levels, you can lane longer, so you will be able to push the enemy lane more. you are hard to gank, because of your high health and your offensive skills can also be used to run, which you should never need to do.

For items, CDR is a MUST if you want high damage output mid and late game. If you like dps, while still keeping survivability, Make sure to include a bloodthirster, Spirit visage, Ionian Boots, and sunfire cape. with those items, your skills will do more damage, your attacks will steal life, along with your high health regen, you have a little more armor and magic resist, you use your skills more often, and your sunfire cape increases your damage output with your AoE skill by alot. If you are more of a tanky charactar, you might want Mercury's or ninja tabi as boots, a warmogs or 2, thornmail, guardian angel, Force of nature, but always include a spirit visage in your builds. you will get healed for so much from it. you could lane forever after your warmogs and spirit visage. you will never go back to heal, be very hard to kill. And you will annoy the **** out of the enemies. if you want a kill early game, replace the Dorans Sheild with a Dorans Blade

Heal: Keep your Squishies alive and in lane longer
Flash: Escapes and Ganks
Ghost: Chase down or escape, Goes great with exhaust
Exhaust: Use with ghost for slow and destroy enemies early game

If you want an early kill, get decisive strike for the silence and high damage, or Judgement for hitting multiple targets. Get your sheild if you want to last hit minions for some quick armor or magic resist. How you want to start is how you feel like playing with him.

Those are just an example of how I set my masteries up. You can change them to suit your playstyle, but thanks for spending your time reading, I know the guide looks terrible, but eventually I will make a new, Revamped guide, once I get the time. This guide was rushed because I don't have much time on my hands, nor will I for the next few months, but my next one will be better(I will add pictures to this guide when I get an hour to get some). so dont troll and say this guide sucks, just leave a comment, tell me what to improve, what is good and bad about my build, I will Appreciate the feedback. :)
