Bind Demon

• Death Mark: +1% Chance to Bind Demon per level

Which Demons It Binds

• Only hard points count toward binding a champion, a unique or a super unique: +skills from items don't.
• A demon only binds once its life drops below a threshold of its own, from 40% to 99%. Its monster page shows it.
• While a demon is below that threshold, Bind Demon tries about twice a second. Each try adds up the skill's own bind chance (in the progression table below), 1% per hard point in Death Mark, and the demon's missing life share from the table.

The Modifiers It Adds

• Level 5: Extra Strong
• Level 10: Extra Fast
• Level 15: Spectral Hit
• Level 20: Aura Enchanted

• These levels count +skills from items, unlike the hard points to bind.
• A normal monster becomes a unique once Bind Demon gives it its first modifier. It keeps a normal monster's life and level, though: it doesn't get the life bonus or the 3 extra levels a unique spawns with.

The Aura

• From level 20, Bind Demon gives the demon Aura Enchanted. The demon's name seed picks the aura, and every demon you bind has a new random one, so binding again finds the aura you want after a few tries.
• A bound demon never keeps Might, Holy Fire, Blessed Aim, Conviction or Holy Shock: each becomes another aura, so only five auras are left. At monster level 20 and up, the odds are:
  • Vigor: 2 in 7
  • Fanaticism: 2 in 7
  • Concentration: 1 in 7
  • Thorns: 1 in 7
  • Holy Freeze: 1 in 7

Life Cap

A bound demon keeps its life up to a cap, which depends on the demon:

• Each player in the game beyond the first raises the cap by 5% of it.
• The cap makes the extra life of a champion or a unique pointless for a demon that already reaches it as a normal monster.

Which Demon to Bind

• Any demon, for the aura. From level 20, a normal monster gets the same four modifiers and the same aura roll as a unique, and binding one takes no hard points beyond the skill itself.
• A champion, for damage. A champion keeps its own bonus on top of the Extra Strong Bind Demon adds. In Hell, that is +165% damage and +115% attack rating, against +99% and +66% for a normal monster or a unique. A Berserker champion goes further: +297% damage and +264% attack rating, but Berserker takes 75% of its life after the champion bonus doubles it, which leaves half a normal monster's life.
• A unique, for its own modifiers. A unique keeps the modifiers it spawned with, on top of the four from Bind Demon. A Cursed unique casts Amplify Damage on what it hits, which no champion does. It also has 3 more levels than a normal one.
• The extra life only matters below the cap. In Hell, a champion and a unique get +100% life. A Pit Lord from the Plains of Despair has 12,500 to 14,900 life as a normal monster, so the bonus lifts it to its 20,000 cap. An Urdar has 11,100 to 13,600, so the bonus adds little before its 13,600 cap.
