I know a lot of Mesmer's do not use mantras so this will only benefit any mesmers that use mantras.
This is a basic exploit to receive 3 mantra stacks instead of 2.
Requirements:
30 points into Domination
Mantra skills
All you have to do is under the Grandmaster Domination Major Trait, is pick out "XI" or Harmonious Mantras. When you cast a mantra you get 3 stacks. Right after then, you can switch that Trait to anything else (I choose confounding suggestions for PvP chain stun spec)
That's all to the exploit.
Now because most of you will think I'm retarded for using mantras I'll give you a spec that is a glass cannon PvE mainly and stunlock PvP.
There are 5 types of mantas (You can have up to 4)
Mantra of Recovery - Instantly heals you
Mantra of Pain - Does damage to your target
Mantra of Distraction - Daze your target
Mantra of Resolve - Cure all of two conditions
Mantra of Concentration - Breaks CC and gives you 2 seconds of CC immunity
In traits if you go
30 Domination - ( Any - Any - XI(3 mantras) + XII(50% chance to stun on daze) )
30 Dueling - (Any - Any - XI (4% extra damage PER readied Mantra)
0 Chaos - (None - None - None)
0 Inspiration - (None - None - None)
10 Illusions - (III (3% more damage per illusion) - None - None)
This is 16% (4 mantras) + 9% (3 illusions) = 25% more damage
I hit extremely hard with this build and if you use the exploit with Mantra of Distraction, you may be squishy but you can stun lock most people if you coordinate it with Sword+Pistol (Blurred Frenzy immunity, Magic Bullet) + Mantra of Distraction + Diversion.
With all the extra %damage, a single Blurred Frenzy does a total of about 10-17k damage.
I use the exploit to help me stun people longer and get insane damage off. IT IS a lot of work to go back and fourth but i like to maximize everything i do.
