Min-Maxing My TRPG Build in Another World: Volume 4

Erich awakens battered and bruised from his fiasco of an errand to find that both he and his ride-or-die Mika have lived to see another dawn.
The pair lug themselves back to the capital with their dubious quest rewards in hand, but the loot doesn't stop there: Agrippina offers our hero another prize... only to disappear somewhere! 
Erich, being the loyal retainer he is, spends all his effort searching for... customers. As his side hustle making custom game pieces starts to take off, one of his customers drops a fresh heap of trouble in his lap! The Henderson readings are off the chart for the fourth act of this power-gamer's journey!
