Well to quote the Noob from battlefield friends
'flanking is charging the enemy head on'
by seriously flanking is attacking from the side
ok...ONLY from the side?? not from behind?
I tested just to see the damage,but not with the exact numbers
Taking all subterfuge tree is useless for stealth attack.
you have stealth,6 dex,6 cun,50% armor penetration and an attack that does 600% damage
It's much better to pick only stealth and then the right side of dual daggers.
Twin fang does much more damage than Shadow Strike.i wrote 700% but is was wrong. It's 1000%
Also Sneak Attacks helps these 2 attacks to be critical
Then i checked Deathblow too.
Ok it does 2 hits when an enemy is wounded but not if he's under 50%. Also if he's at 90%HP,so i think that the health treshold means that under 50% no more bonus damage is applied.
(300+150)x2=900%
Since it's good vs wounded targets,it's not good to use it in stealth for backstab
