Heal and empower your demon by feeding it a corpse.
Engorge is a Warlock demon buff (Demon Skills, level 24, requires Blood Boil, unlocks Bind Demon). It needs a demon out (requirespettype 1, pettype demon) and a corpse to feed it; the demon is healed and gets the engorge state for a duration. Two numbers decide it: the heal, 49% of the demon's life at level 20, and the duration, 62 seconds at the same level.

ln56: Param5 (125 frames) plus Param6 (75 frames) a level, at 25 frames a second: 5 seconds at level 1, 62 at level 20.ln34: Param3 (30%) plus Param4 (1%) a level of the demon's life, 49% at level 20.ln21, the demon's lifedrainmindam and lifedrainmaxdam for the duration: Param2 (1) plus Param1 (15) a level, +286% at level 20.attackrate) is min(ln12, 35): Param1 (15) plus Param2 (1) a level, capped at 35%, so 34% at level 20 and the cap from level 21. The tooltip prints it from the aura stat, which the evaluator cannot embed; the arithmetic above is the calc.Duration, heal, life steal and attack speed read lvl, so +skills count; the two Blood Oath lines read blvl.
Engorge is an aura on the demon with range 1 and length ln56; its six aurastat columns are the damage resistance, the two life-drain stats, the attack rate, the armor class and the regeneration above. The row is stsuccessonly 1, so the state is applied only when the cast succeeds. Nothing on the row deals damage or rolls an attack; the life steal is the demon's, applied to the demon's own hits, see Leech.
The heal is a share of the demon's life, and Blood Oath multiplies that life: on a demon with +715% life from Blood Oath a 49% heal is a large flat amount, and the 5% damage reduction stacks on Blood Oath's resist all.
Two synergy lines in the tooltip, both from Blood Oath hard points: Defense per level (Param11, +25) and Replenish life per level (Param12, +5). Engorge in turn feeds Blood Boil, +20% physical damage per hard point (Blood Boil's DmgSymPerCalc), and Hex: Siphon, a skill outside this page's facts.
A buff on your own demon; it never touches a player. The engorged demon'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.
Written from the game's tables (build 3.3.93847) and the cited pages; a per-level table is computed from skills.txt and skilldesc.txt by the same evaluator the skill pages use. A “legacy rule” is a published engine rule no table proves; a “game table” is read from the table named. · Report incorrect data
