Item effect

Equipable items in have varying effects (aside from damage and armor) depending on their type and tier.
Witcher gear has all effects preset and static, with no change in values. Relic items also have entirely preset effects, but their corresponding values (such as % chance or resistance) may vary. However, item effects on the other three tiers - common, master and magic items - work within a slightly more elaborate scheme:
A common item may or may not have preset effects, but when it does they are both entirely static and more importantly inherited by master and magic items, which get random effects on top of that.
* Master items get 1 random effect, applied on top of the common base.
* Magic items get 2 random effects, applied on top of the common base, but also drawing from a wider pool of possible effects. Additionally, due to the unrestricted randomization, the drawn effects may stack. For example, drawing critical hit chance twice will result in only one visible effect, but with a higher % chance value.
There are only two exceptions to this rule:
#Crossbows (although with varying attack power) and bolts and have enitrely preset effects, regardless of their tier.
#, and any crafted items may have one or both random slots also preset and static. Expansion items also may draw from larger effect pools.
