About Skill/Spell Costs:

So calculating skill and spell costs is a bit weird, based on the wierdness that is the mud. It appears that what happens is the following:

((StartingCost * multiplier) - (starting cost * multiplier % 100)) * race cost

where multiplier is the value found for the corresponding 5% in costs.txt (for example, for 55 -> 60 it is 523)

To verify/update the costs seen in spells.chr and skills.chr, I would suggest using the largest cost under the max cost,
larger values don't have the problem that occurs when you round down to a multiple of one hundred.

Also, while this is what is displayed in both the skills/spells tabs and on the mud, this apprears NOT to be what the cost
actually is, it is actually the value found using estimate, rounded down, again, to a multiple of one hundred.
So if the cost listed is 5090 exp, the ACTUAL cost appears to be 5000 exp. Stupid, I know, but that seems to be accurate.
