Semjaza — The Encounter
the Oathbound Crown — chief of the two hundred, who swore the oath on Hermon. · a boss your table can run with almost no prep. SRD 5.1-compatible.
Who Is Semjaza
Semjaza led the two hundred Watchers who bound themselves by mutual oath and descended to the daughters of men. He is the will that holds the fallen host together, a gargantuan crown of oathbound angels lashed into one throne of eyes and wings. Kill the lesser Watchers and he weakens; kill him and the oath breaks, and the host scatters screaming into the dark.

Semjaza
Gargantuan celestial (fallen watcher), lawful evil
CR 23 · 50,000 XP · GUIDELINELegendary Resistance (5/Day). If Semjaza fails a saving throw, it can choose to succeed instead.
Magic Resistance. Semjaza has advantage on saving throws against spells and other magical effects, and is immune to effects that would sense its location or read its thoughts.
The Binding Oath. At the start of each of Semjaza's turns, each of its fallen-watcher allies within 120 feet regains 20 hit points and has advantage on its next attack roll. While any such ally lives, Semjaza has advantage on death saving throws and cannot be reduced below 1 hit point by a single instance of damage.
Host of Wings. Semjaza is wreathed in a mass of bound angels. It has three-quarters cover against ranged attacks, and any creature that starts its turn within 15 feet must succeed on a DC 24 Wisdom saving throw or be blinded until the start of its next turn as the wings open a hundred eyes.
Actions
Multiattack. Semjaza uses Voice of the Oath if available, then makes three Sundering Grasp attacks.
Sundering Grasp. Melee Weapon Attack: +15 to hit, reach 15 ft., one target. Hit: 22 (3d8 + 9) bludgeoning damage plus 18 (4d8) radiant damage, and the target is grappled (escape DC 24) and cannot regain hit points until the grapple ends.
Voice of the Oath (Recharge 5–6). Semjaza speaks the oath of Hermon. Each creature of its choice within 60 feet must make a DC 24 Charisma saving throw. On a failure a creature takes 55 (10d10) psychic damage and is oathbound (charmed by Semjaza) for 1 minute; on a success it takes half damage and is not charmed. An oathbound creature must use its action to attack a target of Semjaza's choice; it repeats the save at the end of each of its turns.
Bonus Actions & Reactions
Command the Fallen (Bonus Action). One fallen-watcher ally Semjaza can see can immediately use its reaction to move up to its speed and make one attack.
Retributive Wing (Reaction). When Semjaza takes damage, it lashes out; the attacker takes 22 (4d10) radiant damage.
Legendary Actions (3/Round)
Grasp (Costs 1 Action). Semjaza makes one Sundering Grasp attack.
Descend (Costs 1 Action). Semjaza flies up to half its speed without provoking opportunity attacks, and one creature it passes over must succeed on a DC 24 Dexterity save or take 22 (4d10) radiant damage.
Bind the Fallen (Costs 2 Actions). Semjaza reasserts the oath: it ends one effect on itself, and each oathbound creature within 120 feet takes 22 (4d10) psychic damage and has its charm renewed to 1 minute.
A crown of bound bodies opens into a wheel of a hundred eyes, and at its heart a single golden orrery turns. This is the chief who first swore, on the peak of Hermon, that the sons of heaven would descend. He kept the oath. He is still keeping it.

How It Fights — by Tier
Same creature, scaled threat. The traits never change; only the numbers move.
A vastly diminished echo of Semjaza for a mid-level party — same role, far softer numbers. He is the campaign's apex fallen-angel boss — an oath-engine that heals and commands the other Watchers, dominates the party with the Voice of the Oath, and cannot easily be dropped while any Watcher still lives. Run him as the final fight after the host, or solo with lair actions for a legendary encounter.
A weakened Semjaza, still a serious boss. He is the campaign's apex fallen-angel boss — an oath-engine that heals and commands the other Watchers, dominates the party with the Voice of the Oath, and cannot easily be dropped while any Watcher still lives. Run him as the final fight after the host, or solo with lair actions for a legendary encounter.

Run him as the final fight after the host, or solo with lair actions for a legendary encounter. This is its true, overpowered form — a legendary-tier fight.

How a bound creature acts
- A companion acts on its owner's initiative, immediately after the owner.
- It uses the Companion block above — roughly ×0.6 HP and damage, no recharge abilities, and at most one reaction trait.
- It moves freely; it takes its Action only while its owner is conscious.
- At 0 HP a companion is broken, not dead — restored on a long rest unless your table rules otherwise.

Questions, Asked at the Table
What CR is Semjaza?
At its native tier Semjaza is CR 23 — a deliberately overpowered fallen-angel boss. Scale the AC, HP, to-hit, and save DC to the tier line matching your party's level.
How does Semjaza fight?
He is the campaign's apex fallen-angel boss — an oath-engine that heals and commands the other Watchers, dominates the party with the Voice of the Oath, and cannot easily be dropped while any Watcher still lives. Run him as the final fight after the host, or solo with lair actions for a legendary encounter.
How do you actually kill Semjaza?
Break the oath. While any fallen-watcher ally lives he heals them, buffs them, and can't be dropped below 1 HP by a single hit — so a party that ignores the lesser Watchers grinds forever. Clear the host (or at least isolate him), then focus him before Voice of the Oath turns your own party against you.
