Training Time
From Exalted
Buying new Traits, or improving existing ones usually takes a certain amount of in-game time, based upon the type of Trait, and whether the PC has Favoured it.
We will be using a simplified system, where a PC may buy any Favoured Ability or Charm between Sessions, but non-Favoured Traits must wait until a protracted period of Downtime.
Edge-cases and loop-holes will be dealt with on a case-by-case basis, with reference to the original Training Times, the amount of in-game time passing, and Rules Zero and Seven.
