Requirements
The Requirements interface is a modal interface that appears when attempting to perform an action at a skill node with multiple requirements and the player only meets some of them.
Below level requirement
When attempting to interact with a skill node when below the minimum level for that node, a popup appears to display the minimum level requirement.
The text on the interface reads "You need to be at least a level <<level>> <<profession>> to <<action>> for <<variant>> <<node>>".
No suitable items
When attempting to interact with a crtafting facility without any suitable items, a popup appears to display the minimum level requirement.
The text on the interface reads "Your backpack does not contain any suitable <<item type>>".
The main Requirements interface
When interacting with a skill node that the player has the level requirement to use but without the required Equipment, Knowledge, Containers, and Items, the main Requirements interface opens to show all the requirements for that skill node.
The text on the interface reads "To <<action>> for <<variant>> <<node>> you need:".
Each row of the requirements lists a profession level, a number of knowledge points, a piece of equipment, a container, or an item.
Inventory full
If the player satisfies all of the requirements to interact with a skill node that produces more items that in consumes but has a full backpack, a popup appears to show that an empty backpack space is required.
The text on the interface reads "You don't have enough backpack space".
