Incapacitating Strike - stun 'if' caster lower HP then target
Soul Harvest - Ulti recharges from kills passively
Killers blade - heals a bit 'if' target dies
Blur - low miss chance on you
*Mirage - miss caan proc opponent off balance
*Double take(extended blur)
Mark target/piercing mark - heals about 1/2 hp 'if' target dies affected
*reapers mark - same as above but heals a bit more+ little weapon & spell dmg boost for 30 sec
Incapacitate - chance to immobilize7 attacks(rofl)( new skill on 1.6 - 8 light/heavy attacks within duration to proc high dmg attack( 8, really? other classes have skills doing near that dmg with no proc whatsoever)
even shadow cloak(and both morphs ofcourse) have chance to drop xD
strife/funnel health/swallow soul - minor heals based on dmg inflicted(aparently if you damage shield it doesn't count, blocks also reduces this a lot)
siphoning strikes/leeching strikes/siphoning attacks - chance to restore part of hp/mag/stam(depending on morph) via basic or any attack( depending on morph)
that's about 1/3 of all NB spells!
what is common among all those skills? they are not effective, those skills are mostly waste space on skillbar, with few heal exceptions( just because there is no good alternative).
