Thief skills: statuses, Backstab and Shadow Lunge

A dagger Thief can use negative effects to enable stronger attacks. Backstab the Weak gains critical chance for each negative effect on its target; Shadow Lunge gains its extra damage only against a bleeding or poisoned target.

Apply the condition first

Nightshade Mastery works with daggers and swords. At rank 1 its hits have a 40% chance to apply a random Poison, Bleed, Blind or Burn effect; at rank 5 that chance is 80%. Random application makes it useful over several attacks, but unsuitable as a guaranteed opening condition.

Bleeding Dash gives a deliberate Bleed attempt and accepts a sword or dagger. At rank 1 it costs 6 stamina and has a 60% chance to apply a 4-damage bleed for one round. A resisted or failed bleed leaves Shadow Lunge without its conditional bonus.

Backstab the Weak needs a dagger. Its extra crit chance begins at 20% plus 10% per negative effect at rank 1; the per-effect bonus rises to 30% at rank 5. One effect is one condition, even if its duration has been extended several times.

Shadow Lunge unlocks at hero level 6. It requires a dagger and adds 50% against Bleed or Poison at every skill rank. Freeze or Blind alone does not satisfy that condition.

Keep the front row alive

Evasive Roll opens at level 3 and is a free action. It increases both Evasion and the normal 60% cap for two rounds. Use it before attacking, especially if the Thief is occupying the front row while the other hero is injured.

Smoke Bomb opens at level 4, can affect up to two enemies and causes Blind for two rounds when it lands. Blind removes 50 hit-chance points from physical attacks; spells still hit. This makes the skill more protective against weapon attackers than enemy casters.

Shadow Instinct at level 5 adds Armor Pierce as well as crit chance. Pierce helps small dagger hits cross the Armor threshold that must be passed before Sharpness and crits matter.
