Void form and melee stealth is OP on NG+10 extreme

[Emphoise]

The higher ranks of void form don't cost a lot of energy, so you can pretty much always stay in stealth mode when you're clearing a dungeon.

While using void form, you're about as invisible as a character with max stealth perk in skyrim.

the new quantum edged melee weapons now do sufficient damage to take out enemies on NG+10 full extreme settings in one or very few sneak attacks.

Combining maxed stealth and concealment skills with high ranks of void form effectively resurects the skyrim dual dagger stealth build, except that you can run, jump and boost pack while in void form which is so much more fun than crouching all the time.

The gameplay is :

1)enter room with hostile npcs inside
2)cast void form
3)run to enemy, press crouch, melee power attack
4)repeat until enemy is dead
5)repeat 3) until the room is cleared of enemies.

Void form does NOT put you in "stealth mode" but it DOES make you pretty much immune to enemy hits. They will know you're there and panick fire, but you can easily avoid them.

When you do crouch while in void form, even if enemies know you're there, you will count as stealthed for sneak attack modifiers as long as you're in "caution" state. You can easily abuse this and just run to enemies, crouch only for 1 or a few hits with sneak modifiers, stop crouching and jump to the next target.

Thing to remember : looting items on the ground and opening doors breaks the void form. Not sure about looting corpses (seems to break it sometimes, sometimes not).

Advantages : No ammo used, you only need a quantum edge wakisashi on NG+10 to make it work (best weapon would be an instigating + shattering + whatever effect quantum edged painblade with the proper weapon mods)

Cons : Removes any challenge from the game (you can refresh void form even if you're not done clearing the room). Bad against turrets (often annoying to reach with melee), not usable in 0G environment.
