what do i build on new sion

Full DPS

I feel heavy tank goes well with Frozen being a core then just hard metal shielding for your team.

Tanky is the best approach for the new sion, you still put out the damage early and can survive to dish out more Q's.

It's the funnest way imo because you don't die in .5 seconds, he now has the lowest base health at level 18 of any champ so he's fairly squishy.

Mild bruiser/Tank. 2 damage items with the rest being health/defenses. As a jungler i feel that the jungle item that builds out of quill coat goes really well with him since it gives you 25% more hp
