Arterius, the Last Watcher

Arterius, the Last Watcher is a flame-wielding knight from NightFall: Invade who guards the Gate of Disaster. In Soulrend the gate only exists in the Past, the dimension of Act V, and Arterius is one of the act’s two bosses. In game it appears as Arterius, The Last Watcher.

Location#

Arterius waits at the Gate of Disaster (nightfall_invade:gate_of_disaster), which Soulrend places only in the Dead Wasteland biome of the Past, at most once per 70 × 70 chunk area. The Past is reached with the Emblem of the Past (see The Past).

No Past soldiers spawn within 96 blocks of Arterius.

Stats#

The NightFall mod gives Arterius 400 health and 4 attack damage. In the Past, Soulrend replaces those bases with 12,000 health and 2,000 attack damage when it spawns, and the level bonus then multiplies the new bases. It has no level setting, so its level is the nearest player’s Soulrend level. The last column uses Act V’s typical level, the player cap of 200 (see Mob Levels).

Stat Mod base Past base Level 200
Health 400 HP 12,000 HP 728,400 HP (364,200 hearts)
Attack damage 4 2,000 41,800
Armor 30 30 95.7
Armor toughness 20 20 20
Knockback resistance 25% 25% 25%
Movement speed 0.45 0.45 0.45

Arterius isn’t on Soulrend’s boss damage list, but the NightFall config gives it its own defenses:

  • A single hit can’t take more than 8% of its maximum health (58,272 HP at level 200).
  • After it has taken 4% of its maximum health (29,136 HP), it starts reducing damage, up to 90% once it has taken 12% (87,408 HP). The reduction fades back to 0 over 8 s.

Attacks#

Arterius fights with Epic Fight animations. Each hit:

  • deals extra damage equal to 1.2% of the target’s maximum health;
  • adds fire damage equal to its attack damage;
  • applies a level 6 debuff for 3 s.

Hits on a target that already has the debuff deal 30% more of its attack damage and 5% of the target’s maximum health on top.

Strategy#

  • Spread damage out. Burst damage runs into the 8% per-hit cap and then the damage reduction, which takes 8 s to fade.
  • Avoid back-to-back hits. Its debuff makes every following hit stronger.
