So I've seen a lot of reference in the rulebook to Living, Undead, Spirit, Construct Characteristics and I'm curious: TTB Mechanics wise - What is the purpose of these characteristics?
In other Pen&Paper games they usually have a tooltip or explanation of what can/cannot effect these but a lot of abilities have specific references such as "Undead Characteristic is immune to the Bleeding Out condition" whereas a living character will suffer from it.
Is there anywhere in the rulebook or elsewhere that explains the purpose/bufs/debuffs of characteristics?
