Dodge bonus

The dodge mechanic works as a miss chance - a simple percentile chance to completely avoid physical attacks. You will see a "Dodge" hover over your character anytime it helps you dodge an attack.

Dodge chance mechanic
This check is done independent of the miss chance resulting from Armor Class and other measures of not getting hit, such as Concealment or Incorporeality. The dodge chance is capped by the Maximum Dexterity Bonus of the armor worn and cannot exceed 25% without special feats or enhancements, such as Uncanny Dodge (see below) that allow a player to exceed this cap. Dodge bonuses from spells, enhancements, epic destinies, items, and feats stack.

As of Update 19, dodge bonuses on items no longer stack, only the best applies.

As of Update 42 Patch 4, there's a second hard cap on Dodge: it can never exceed 95%.

Dodge bonus to Armor Class
Previous to Update 14, Dodge used to be considered a bonus type, generally applying to armor class and sometimes reflex saves. In some very rare areas where the devs forgot to update the bonus types, there are still a few abilities/items that display as dodge bonuses to armor class in the breakdown, but officially the system has been discontinued, so they should be considered bugs.

Examples are:
 * Eldritch Shield Ritual and Eldritch Armor Ritual (Technically should count as bonuses types equal to their name per a dev post)
 * Favored Defense I to III +1-3 (Ranger only, vs. favored enemies)
 * Fighter's Mobility I to II +1-2 (fighter only, only while tumbling; requires Mobility feat)

Dodge stacking
The Dodge bonus always stacks, except the ones you get from items. As of update 19, only the highest item based Dodge bonus will apply.

Prior to update 19, there were some issues with stacking sometimes. Depending on the order you equip your dodge items, the final result may not be correct. A work around for it was stripping off and re-equipping in a different order.
