Play with Dark Ritual augment to convert cash out -> AP. Ideally ply for a 250+ cashout for AP first, then take 40s if you need for more stacking. 2x Morgana 2* with items on both is the best way to cap your board.

Stage 2: Ideally open with Coven and start gathering Essence. It is actually better to win early than lose for stacks so don't overly force lose streak.

Stage 3: Level to 6 and roll for a Elise 2, Covens, and Vanguards. Give Cassio or Diana leftover AP. Cash out Coven and convert to AP with at least 2-3 lives (25-30 hp).

Stage 4: Finish Elise 3 / Cassio 3 then level for more Vanguards or Lunar. Play 2 Morganas with items if you have extra.
