Adds poison to your dagger attacks.
Poison Dagger is a level 6 Necromancer melee skill (Poison and Bone tree, no prerequisite; it unlocks Poison Explosion). It is a normal weapon attack that needs a dagger in hand (itypea1 "knif" in skills.txt) and, when it hits, adds poison damage over time: 7–15 over 2 seconds at level 1, 540–581 over 9.6 seconds at level
per hard point. Mana is 3 at level 1 and 7.75 at level 20.

Every line reads the full skill level, so +skills count; the synergy reads hard points only.
Poison Dagger is a melee attack: it rolls Chance to Hit with your Attack Rating plus the skill's bonus, swings at your weapon's speed (see Attack Speed), and on a hit deals the dagger's full physical damage (SrcDam 128, which the Basin lists as 100% weapon damage) and then applies the skill's poison. The poison is reduced by the target's poison resistance and stopped by a poison immune (see Poison Damage and Dealing Elemental Damage).
The Basin's rules for how the poison combines with other poison:
The dagger requirement is absolute: with any other weapon the skill cannot be used, and a miss applies no poison.
Two skills feed Poison Dagger, each at +20% poison damage per hard point (Param8 20, "Damage synergy"): Poison Explosion and Poison Nova. The column is EDmgSymPerCalc, which reads each skill's blvl, so +skills from items add nothing to the synergy. Poison Dagger gives a synergy in return to both of them. There is no poison mastery; Poison Skill Damage from items is the outside multiplier, and poison length is not changed by the synergies.
A player's hit on another player is cut to 17% of its value (difficultylevels.txt PlayerDamagePercentVSPlayer) before anything else, for the stab and for the poison alike. The Basin's page records no other player-versus-player rule for this skill. See Player versus Player.
