Wooh, that was hard day and quite small time for gamedev.
Today's update about logic.
As yesterday I worked with Writing UI, today I focused to creating mechanics of Writing Craft:)
First thing - created a required skill level and modifier to build the writing over time.
Secondly - created basic algorithm which takes Element, TimeDelta and an Artisan person to apply skills and increase durability (health) of the element (Writing).
And third thing I finally released how to connect specific to object properties - attributes but keep in the same time universality of the common world elements by using WorldElement class a container.

So that's all for today)
