Hex: Siphon

Hexes your weapon to extract the lifeforce of slain enemies.

Hex: Siphon is a Warlock weapon buff (Eldritch Skills, level 24, requires Hex: Purge, the last skill of the hex line). It needs a weapon (requiresweapon 1, item type weap, not hand-to-hand) and puts the hexsiphon state on you: your weapon gains attack rating and a life-and-mana-after-kill line, and each hit puts the hexsiphondebuff state on the target, which cuts the target's damage. The numbers that decide it are the harvest, +20 life and +20 mana after each kill at level 20, and the debuff, −33% damage dealt at every level.

The numbers

• Mana is 12.5 at level 1 and rises 0.5 a level (mana 25, lvlmana 1, manashift 7) to 22 at level 20.
• Duration is ln34: Param3 (3,600 frames, "Hex Duration baseline") plus Param4 (300 frames) a level, 144 seconds at level 1 and 372 at level 20.
• Life after each kill is passivecalc3 on item_healafterkill: ln12, Param1 (1) plus Param2 (1) a level, so +1 at level 1 and +20 at level 20, plus Param9 (1) per hard point in Engorge. Mana after each kill is passivecalc5 on item_manaafterkill: ln56, Param5 (1) plus Param6 (1) a level, the same +20 at level 20 with the same Engorge term. The table's comments call the pairs "Life/Mana drain baseline" and "per level".
• Attack rating is ToHit (20) plus LevToHit (9) a level, +191% at level 20, on item_tohit_percent (passivecalc1).
• Debuff duration is calc1: 150 frames plus Param8 (5 frames) per hard point in Eldritch Blast, 6 seconds with none, +0.2 seconds a point; it never changes with Hex: Siphon's own level, so it is left out of the table.
• Enemy damage is aurastatcalc1 on damagepercent: a flat −33% on the hexed target at every level, which matches Param11 (33, "damage % baseline"). Param12 (3, "damage % steal per level") and Param10 (1, "Damage% synergy") are not read by any calc on the row, so the −33% does not grow.

Duration, attack rating and the after-kill lines read lvl, so +skills count; the Engorge and Eldritch Blast terms read blvl. The passive lines need one weapon equipped (passivereqweaponcount 1).

How it works

The buff is an aura state on you with length ln34 whose events are domeleeattack, domissiledamage and hextrigger (all func 36): a melee attack, a missile hit, or a hex trigger puts the hexsiphondebuff state on the target, and that state carries the −33% damagepercent. The weapon lines are ordinary item stats while the buff lasts: item_tohit_percent feeds your Chance to Hit, and item_healafterkill and item_manaafterkill are the stats of Life after each Kill and Mana after each Kill, paid once per kill you make. The hex adds no damage of its own: the row has no EMin, EMax, SrcDam or damage calc. Casting is allowed in town (InTown 1).

The harvest is per kill, not per hit: +20 life and +20 mana at level 20 only pay out when the blow that kills lands, and the −33% debuff is flat from level 1.

Synergies and +skills

One synergy: Engorge adds +1 life and +1 mana after each kill per hard point (Param9). Eldritch Blast adds 0.2 seconds of debuff per hard point (Param8, calc1). Both read blvl. Hex: Siphon feeds no other skill: no row names it in a synergy calc, and its skilldesc has no "gives" line. There is no mastery line on the row.

Against players

The hex adds no damage of its own, so the player-versus-player rule, which cuts a player's hit on another player to 17% (difficultylevels.txt PlayerDamagePercentVSPlayer, see Player versus Player), has nothing of this skill's to cut. The table has no separate player value for the −33% damage on a hexed target or for the after-kill lines.

Build notes

• The after-kill lines grow 1 a level each, so a +skill is worth exactly as much as a hard point here; Engorge hard points add 1 to both at once.
• The −33% enemy damage is the sure part: it is on the first hit at level 1 and never changes.
• Mana is 22 at level 20 for 372 seconds of buff; the attack rating line (+191% at level 20) is the same ToHit 20 plus 9 a level that Hex: Bane and Hex: Purge carry.
