Wealth
As discussed above, money is generally a minor boon and GMs can dispense it as they see fit, but extremes of either wealth or poverty can have some effect on character's ability to muster resources that may help them accomplish their goals. Consequently the following assumptions are made throughout these rules in terms of the likely sums of money, goods, and services available to PCs.
Tier Treasure Size Insignificant Significant Major
Heroic 100sp 10cp 50sp 20gp
Legendary 100gp 10sp 50gp 200gp
Mythic 1000gp 100gp 500gp 5000gp
Tier indicates one of the three tiers of play, as discussed in Legendary Heroes. Treasure size indicates the general scale of a monetary reward acquired as a minor boon at that tier. The last three columns indicate the general scale of outlays which a character might make in terms of whether or not they are insignificant (basically pocket change), significant (something worth consideration but not large enough to drastically effect the character's finances), or major (an amount the character will need to account for in her plans).
Generally these amounts can be extrapolated between tiers, so a level 7 PC might find insignificant expenses as much as several sp, while a 200sp expense might now be significant but not major.
In general heroic tier characters may be concerned about meeting everyday living expenses. Legendary characters may be concerned with significant fortunes and remarkable wealth. Epic characters are generally beyond normal monetary considerations, but may sometimes become involved in adventures revolving around truly fantastic fortunes, sources of vast wealth, etc.
Note that this general scaling is also carried into the equipment tables, ritual costs, item fabrication costs, and NPC wages as well.
