 ==Calculating AC Value==
-===Base AC & Armour skill===
+In order of operation:
 Your total "base AC" is equal to the ''sum'' of the base AC values from every worn armour. This excludes any armour [[enchant]]ments you may have.
-Then, [[Armour skill]] provides a bonus to AC, using your base AC:<ref>{{source ref|0.28.0|player.cc|5691}}</ref>
+===Multipliers===
     (base AC) * (1 + Armour_skill / 22)
 This is roughly equivalent to +4.5% base AC per level of Armour skill. AC is calculated to 2 decimal places, and most displays show this value rounded down. Item descriptions will, however, show your AC rounded to 1 decimal place, together with the change in AC from equipping or removing that item.
