Summon Defiler

Summons a defiler that binds enemy souls together to take shared damage.

Summon Defiler is the Warlock's third summon (Demon Skills, level 18, requires Summon Tainted, unlocks Bind Demon). It calls a Defiler (summon warputriddefiler, pettype demon, summon mode S3) that casts Health Link at its own level, binding enemies so that damage to one is shared. The numbers that decide it are the demon's +10% damage a level, which here also counts +10% per Demonic Mastery hard point, and the Health Link share, which is Health Link's own row.

The numbers

• Mana is 35 at level 1 and rises 0.5 a level (mana 70, lvlmana 1, manashift 7) to 44.5 at level 20, the most expensive of the three summons.
• Defense is ln78: Param7 (125) plus Param8 (20) a level, 505 at level 20. Param5 (35), which the table's comment also calls "Defense per level", is not read by the calc.
• Life is calc1, "HP % Modifier": Param1 (35) × (level − 1), plus Blood Oath's Life of your demon line, so +665% at level 20 from this row.
• Damage (damagepercent) is Param2 (10) × ((level − 1) + Demonic Mastery's hard points): +190% at level 20 with no Demonic Mastery, +390% with 20 hard points in it. Unlike the Goatman, this row does not add Demonic Mastery's own Damage line; it reads its blvl instead.
• Attack speed (attackrate) is only Demonic Mastery's attack speed line, capped at 25%; the row has no attack speed line of its own. Run/Walk copies Demonic Mastery's dm91.

Defense and life read lvl, so +skills from items count; the damage line's mastery term reads blvl.

How it works

Health Link is cast at the summon's level (sumsk1calc = lvl). The tooltip's two Health Link lines, the damage share and the number of bound souls, follow the diminishing formula (110 × level × (max − min)) ÷ (100 × (level + 6)) + min on Health Link's Param1–2 and Param3–4, with the Defiler's level as the level. Health Link's row is not in this page's facts, so the share and the soul count are not given here. The row's second summon skill is Summon Defiler itself at lvl.

The Defiler has no tohit passive and no flat damage line, only the damage percentage. It copies your item_pierce_damage_immunity stat (see Monster Physical Immunity is Sundered), takes Blood Oath's dm91 as its physical damage resistance, and can be cast in town (InTown 1) with a 15-frame local delay (0.6 seconds). Its cap is Demonic Mastery's ladder: 1 demon, 2 at 5 hard points, 3 at 10.

The Defiler's damage is the one demon line that reads Demonic Mastery's hard points, not its level: +10% per hard point, and +skills in Demonic Mastery add nothing to it.

Synergies and +skills

No synergy lines in the tooltip. The row reads Demonic Mastery's hard points into its damage and Demonic Mastery's lvl lines into its attack speed and run/walk, and Blood Oath's life and physical damage reduction lines. Summon Defiler gives a synergy to no other skill.

Against players

The Defiler's hits on a player are cut to 17% of their value by the player-versus-player rule (difficultylevels.txt PlayerDamagePercentVSPlayer), see Player versus Player. The table has no other player-specific value.

Build notes

• Each level here is +10% damage, +20 defense, +35% life and a higher Health Link; each Demonic Mastery hard point is another +10% damage on this demon alone.
• At 44.5 mana a cast at level 20 this is the costly summon; the Goatman is 24.5 and the Tainted 34.5 at the same level.
• The demon count still comes from Demonic Mastery's hard points, not from this row.
