This build is to completely max damage on gragas. With the magic penetration and the absurd AP, 1 barrel can be doing up to 700-800 true damage with an instant recast. You also play first strike to get extra damage, not really worrying about the gold, although it is very useful to get fed.

Well... It's kinda garbage in jungle gragas. Save that for when you're in top lane. You just can't put out as much damage as you need to to 1v9 as tank gragas. If you're going tank gragas, I recommend building "Shadowflame" and "Demonic Embrace." They both give you health so you get more tanky, but they also give you more damage instead of just being a pure meat shield.

If you want to be a true Gigachad gragas player, use either the "Hillbilly Gragas" skin or the "Vandal Gragas" skin. these are obviously the most Gigachad. Also, in December, you must always use "Santa Gragas." Even if you have to pay. No exceptions allowed
