Evasion is a rogue talent from the Below the Belt tree in Dragon Age: Origins.
Information
Grants +20% Chance to Dodge, +20% Resist Stun/Knockdown.
Notes
- This passive is quite a mixed bag due to the attack animation interrupts it forces. In this respect, 20% dodge provided by this ability is radically different from 20% dodge from any other source. In fact, it's doubtful whether these two kinds of dodge should be considered the same mechanic. Whenever a character successfully dodges an attack with
Evasion, attack animation interrupt is always forced and an Evasion effect icon briefly appears; on the other hand, whenever a character successfully dodges an attack with, for instance, 
Cailan's Greaves, there is no animation interrupt, and no status icon, just no damage is dealt. This is clearly demonstrated in these two videos: Evasion (20% dodge) vs Cailan's Greaves (20% dodge).
- +20% Resist Stun/Knockdown needs a clarification. It's not a physical resistance bonus, it's a flat 20% chance to ignore any stun/knockdown effect. Normally unresistible abilities like Ram and Scattershot may be resisted this way.
- The effect adds to displacement property, and is stackable with other sources, such as from items. While chance to dodge is 20%, the chance to play the interruption animation is only 15%, regardless of how much the property is stacked:
- With just Evasion and no other sources of Chance to Dodge, you have a 5% chance to dodge without interruption and a 15% chance to dodge with interruption.
- With Evasion and Cailan's Greaves (adds 20%), you have a 25% chance to dodge without interruption and a 15% chance to dodge with interruption.
- There is no interruption for resisting stun/knockdown.
- It is quite easy to reach a high level of dodge for rogues in Dragon Age: Origins through gear and talents:
- Evasion (+20%) + Dark Passage (+5%) + Battledress of the Provocateur (+15%) + Cinch of Skillful Maneuvering (+10%) + The Spellward (+10%) + First Enchanter's Cowl (Origins) (+10%) + Cailan's Greaves (+20%) = +90% dodge.
- 18 out of 20 attacks will miss you without even factoring in your defense.
