Alter Aeon FAQ (Frequently Asked Questions)
FAQ 5.6 - How does AC and armor work?
AC and armor protect you from blows by reducing damage when you are hit.
A higher armor score is better, for example 200 armor is better than
0 or 100. Negative armor is very bad, and makes you more vulnerable
For ARMOR equipment, you want the Ac-Apply to be high. 9 Ac-Apply is
better than 5 Ac-Apply, sometimes a lot better depending on where the
item is worn.
On magical items, a positive ARMOR Affect is also good:
Affects: ARMOR by 8 is better than Affects: ARMOR by 3. Note that it
is possible to have negative armor, which will actually make you more
vulnerable to attacks if you wear it. Avoid items with negative ARMOR
