One thing, this is a support tank build if you're looking for kills go elsewhere

he has no AP skills at all but they are all magic damage so i chose spell pen. 2nd thing he burns mana even with manamune so the mana per lvl seem to work out best and cool down is for late game when you spam ghouls baby. I think the health is self explanatory.

Basic support tank 0-21-9

the build has two variations for AD enemies use the build shown and for AP switch the frozen heart for banshee's veil and if the enemies have little Crowd Control switch out Elisea's for spirit Visage.

Play it safe, yorick is very easy to kill early on farm with your abilities, harass only if your partner is a carry and needs early kills, go back for your philosopher's stone as soon as you get 365 remember the longer you have the better.

Look for team fights and ult your carry, 2 of the same carry equal better for your team.

Remember Support Tank play it to save others and work on helping your team.
