Dodge bonus

Overview
The term dodge bonus can refer to one of the two following things: A chance to evade enemy attacks or a bonus to Armor Class with the type 'Dodge' (opposed to e.g. armor bonus).

Dodge Chance
The Dodge Chance provides a chance to evade enemy attacks introduced with Update 14.

This check is done independent of the miss chance resulting from Armor Class and other measures of not getting hit, such as Ghostly or Displacement. The dodge chance is capped by the Maximum dexterity bonus of the armor worn, and cannot exceed 25%. There are some abilities (see below) which exceptionally allow to exceed this cap. Note that dodge bonuses can stack with each other. All dodge bonuses from spells, enhancements and feats stack, but identical magnitude dodge bonuses from treasure do not stack in DDO. So a +3 % dodge bonus on Dragontouched armor will not stack with a +3 % dodge bonus from Chattering Ring. But a +4 % dodge bonus on the Icy Raiment will stack with the +3 % from Chattering Ring.

Dodge Bonus to Armor Class
There are some items and spells which give a Dodge typed bonus to AC, for example the Eldritch Shield Ritual and Eldritch Armor Ritual as well as the Haste spell.

Before Update 14, most of the items with a Dodge chance bonus were providing a bonus to AC. Except for same-numbered bonuses from items (which currently do not exist), all of these dodge bonuses stack with each other.

Dodge AC Bonus Limitations
It is written in DDO user manual (p.74) that dodge bonuses only stack up to a maximum of 10, unlike in PnP D&D there is no limitation (Dungeon Masters Guide p. 21, Players Handbook p. 136, 307). But that is not really the case in game. You can benefit from more than 10 dodge bonus. It is unclear whether it is intentional or not.

Dodge Bonus Item Stacking

 * The dodge bonus from haste spell stacks with dodge bonus +1 item (such as Alchemical Armor Eldritch Ritual)
