If you have to reduce bonus by even 1, it's not worth going to 50AP. Technically you can reduce -1 servant for 50AP and retain sock equivalence, but 40AP will be quicker regardless. 50AP can suck it. I'm already traumatized wasting a quartz after my command seals just to get Scathath's last 10k HP. I dunno how people were theorizing (50) David, (50) Robin, (80) Salter were supposed to cut it to round 3 intact with NPs drawn --- my entire front line got demolished by Altera and her lancer buddies.
