Clearer description for things in general?

Just an example with some currency orbs, like Vaals and Divines..

So Vaals do not always "unpredictably modifies" an item, right? So why don`t you say "IT HAS A CHANCE".

Can Divines change the base damage of an item? Or the tier of a modifier? Or only the values within the same tier already on the item?

There are a lot of examples like this within the game, not only for currency and I hate I always need to go online and search for an answer.

CMMOONNN men. Why is it so hard to keep us in the game??
