Powers:I'd mostly like to see level 3 added to most of the powers.
-III Slow Time - gives new spell.allows you to briefly reverse time.
-III Blink - Can now blink to higher platforms. (blink goes further when pointed forward or down. this would let you blink higher when aimed upward.)
-III Possession - gives new spell. Can now possess someone to attack his friends while you still remain in control of Corvo
-III Rat Plague - rats no longer attack you unless you are very near.
-III Wind Blast - gives new spell. Can pull objects or people to you silently.
Gadgets:-Springrazor Bolt. So you can deploy them at extreme range.
-Gas Mine - non-lethal trap
-Sap - some sort of nonlethal sword to be wielded int he R. Hand. (make it have a "stealthkill" animation. Make the perk of choking to where you automatically carry them after choking and remove the hold X or Square or whatever while choking to do that.)
-distraction bullet - a low-velocity bullet that fires so quietly it won't alert guards, but will make lots of noise at the target. (long range distraction)
