Decimal is a barrel-shaped automation who was repaired by a merchant and given away to House Wolffort. It sings and dances, though it does sometimes wonder who invented it and why. Decimal is one of three characters (along with Giovanna and Quahaug) who are difficult to get in your first playthrough because of the conviction strength you need for all three alignments.

To get Decimal, your Morality level needs to be really, really high—much higher than your Liberty and Utility, which need to be pretty high, as well. Exchanging Kudos for items, winning Mental Mock Battles, talking to NPCs, and ending a turn without doing anything are some ways you can raise Morality.

However, the things that raise this conviction the most are providing law-abiding answers during dialogue prompts and choosing green paths when you consult the Scales of Conviction.

Decimal’s formal title is the “Mathematician”—and for good reason. All his skills require a bit of mental math to determine its effect. For example, it can inflict different effects depending on what number the enemy’s HP is divisible by. It’s best used in offensive teams who usually exhaust their TPs to zero.
