Prio Item Augments

6 sorc 4 emissary
Changed 6 sorc so it has the passive of 8 sorc.
Can only fit the board on 8 if you have a sorc +1, otherwise play 4 sorc + 4 emi + elise until level 9, then drop elise for 6 sorc.

Zoe: shojin + ap damage items (jg, guard)
Leblanc: adaptive + red + shiv
Garen: generic tank.

Zeri Reroll
The comp was already pretty strong in the right spots and they buffed vander, scar, and garen.

Roll for Zeri and Vander 3, then push 8 for 6 watchers.
If you have a lot of scars roll for him, otherwise go 9 for legendaries/6 costs.

zeri: 2x guinsoo + gunblade
vander: generic tank.
