Lord De Seis

Back when he was really dangerous.

Lord de Seis is Undead, and an Oblivion Knight.

Lord de Seis is one the 3 "Seal Bosses" found in the Chaos Sanctuary in Act Four. De Seis is freed by opening the rightmost seal.

Oblivion Knights are one of the most feared monsters in the game due to their ability to cast dangerous curses. Iron Maiden is the most dangerous, a curse that has caused countless melee fighters to kill themselves in just one or two hits. It has no effect on ranged attackers though, so Sorceresses, Bowazons, and other ranged attackers have little difficulty with de Seis or Oblivion Knights in general.

Prior to v1.07 Lord de Seis was much more dangerous, since he spawned with a full boss pack of Oblivion Knights. Since the v1.07 patch he's become much easier, since he now spawns with Doom Knights. His aura was also changed in v1.07, from Conviction to Fanaticism.

Prior to v1.04, Lord de Seis had the Thief property, an unusual monster modifier that caused potions to drop from a character's belt. That mod was buggy, and was removed from the game in v1.04.

All values are listed by difficulty level: Normal / Nightmare / Hell.

Statistics

• The TC/Rune drops listed are the highest Treasure Class/Rune Group a normal monster of that type can drop.
  • Champions and Bosses can sometimes drop from the next higher TC.
  • The max TC/Rune possible depends on which level a monster spawns in, and can vary slightly from the listed values (monsters that spawn in later levels can drop higher level items). See the item calculators to ascertain precisely what a monster from a given area can drop.

Defense

Like many other SuperUniques, Lord de Seis does not regenerate hit points.

• Regen Rate tells what % of a monster's hit points are recovered per second. Standard is 1.2/sec.
• Blocking tells what % of successful, blockable attacks will not damage the monster. Monsters need not carry a shield to block.
• Drain Effectiveness tells what % of a character's mana and life steal apply to that monster. 100 is all, 0 is none.
• Chill Effectiveness tells what % of a character's cold length applies to the monster. 100 is all, 0 is no freeze/chill at all.

Name	Defense	Blocking	Regen Rate	Drain Effectiveness	Chill Effectiveness
Lord de Seis	192 / 910 / 1898	--	--	100 / 75 / 33	50 / 40 / 25

Resistances

• Resistances over 99% are listed as immunities and monsters will take no damage from that type of attack.
• Immunities can be "broken" by skills that lower resistance, if the value drops below 99%. See the Resistances page for more details.
