This is the screen for Armor/Shield Abilities. You can select whether it's an Armor Ability or a Shield Ability or both.
You can select the Armor/Shield type that this ability is for, assuming it isn't for all types. You can also choose the Alignment type. By default, Magical Armor/Shields are not capable of Intelligence, but it is an option.
This is the Specific Armor/Shield part of the screen. As an example, Demon Armor would not have a Neutral or Good alignment, so it has Evil as it's default. You can make an Armor/Shield be always Intelligent and have a specific Intelligence, if wanted. Intelligence is detailed on the Intelligence page.
