Gaining Stats from other Stats

Gaining a percentage of stat A as stat B is calculated from the base value of stat A. The portion gained scales with percentage modifiers to stat B, but not with percentage modifiers to stat A. For example, if you gained 50% of [Evasion] as [Armour], the portion gained would be scaled by percentage modifiers to [Armour], but not by percentage modifiers to [Evasion].
