Leaked internal patch notes

Mechanics

Clone health: INCREASED BY 50%, due to health modifier being increased from .2 to .3.
Downed: Mind blast multiplier increased from .5 to .6.

Greatsword

Bouncing Blade now applies 3 stacks of might when it hits an ally, and applies vulnerability to foes. Might duration increased from 5 seconds to 10, and damage multiplier increased from .6 to .7.
Mind Stab still hits multiple targets, but now instead of applying vulnerability, REMOVES BOONS FROM FOES. Damage multiplier also increased from .7 to .85.

Utility

Mirrored Feedback now casts instantly and has 40 second cooldown instead of 45 seconds.
Veil no longer cloaks allies that are already cloaked, so no more 20 second stealth stacking.
Mantras now double cast by default, and are balanced accordingly. With the trait, they now triple cast, including mantra of recovery for both double and triple.
Arcane Thievery: Bug fixed where recharge would be increased if you had Far Reaching Manipulations.

Heal

Cooldown on Mirror is now 15 seconds instead of 30 seconds.
Mantra of recovery now heals half as much but can be used twice by default, three times with the trait.
