Targon Aurelion Sol

Aurelion Sol wants Adaptive Helm, Blue Buff and Rabadon's Deathcap, mana sustain into a huge AP payoff, since his damage scales directly off ability power and he casts constantly once he has enough mana. Diana takes Bloodthirster, Guinsoo's Rageblade and Titan's Resolve for a more melee brawler AP build, while Taric and Leona both go the identical tank line of Gargoyle Stoneplate, Spirit Visage and Warmog's Armor.

Since Targon has no trait to chase, prioritise flat power augments over synergy ones. AP, mana, or stat augments for traitless units all disproportionately benefit this comp. Econ is still king before stage 4 given how gold hungry hitting a seven cost carry is.

Azir, Xerath, and Nasus can be swapped out depending on what items and levels you find. Zoe and Aphelios are cheap enough to hold items early while you build toward Aurelion Sol.
