Hello, I saw this:

Evade


Evade formula includes such elements as your level, your target's level, your level of evade, your QUI, your DEX, your buffs to QUI and DEX, the number of people attacking you, your target's weapon level, your target's spec in the weapon he is wielding, the kind of attack (DW, range, etc), attack radius, angle of attack, the style you used most recently, target's offensive RA, debuffs, and a few others. (The type of weapon large, 1H, etc doesn't matter.) So it's entirely situational. Grab Bag 12/13/02
Base chance to evade at Evade 7 is 35% (5% per level). Dodger 5 (3% per level) adds another 15%. But that's just a BASE. Those percentages can be modified by all of the above. The cap is 50% - but after your base is modified, you might not be at 50. Grab Bag 12/13/02
Evade is not a skill, and it works very differently from parry and block. Primarily, the effectiveness of evade is related to your level of evade (and of course, your level versus the level of your target). There are many minor factors, of course, but that is the big one. The stats that affect evade are dex and qui in equal proportions, just not in as large a proportion as they are in parry or block. Grab Bag 10/25/02
Evade is not affected by a dual wielder (enemy). Grab Bag 10/18/02 <-- couldnt find that reference though

SO can you confirm that evade is not halved by dual wield?
