Description
Those who dare cross the line and try to dismantle the city of Aetherfall first must face the might of the Aether Guard. Seen by the few, yet rumored by the many the Aether Guard serves the cities government directly, and act as a bulwark against the darkness outside. They are among the few individuals aware of the potential threats and truth that awaits humanity outside the city, and withstand lifelong vigils with honor.
Stationed within the castle bastion of the Arcaneum, the Aether Guard run drills and train aspirants while not resting within its walls. Only being deployed to face the worst of threats, many of the Aether Guard spend their days reveling in war games and maintaining their armaments. These individuals are chosen from a pool of noble lineages brought on board Aetherfall for generational selection, and are beholden to arcane oaths sworn before they are even born.
The Aether Guard acts as the primary wing of the Legion Arcanum, and are divided into three distinct companies. The 1st Company consists of the veteran Aetherian Vanguard consisting of those who have shown their capability to protect, and to act as a bulwark against the darkness time and time again.
Study the Foe
Characters proficient in Arcana or History gain Advantage on Intelligence (Arcana) checks to study a Aetherian Sentinel, revealing the following based on the result:
(15+) Supremely Warded. You identify it gains half-cover when one or more of its Force Cannons are active.
(20+) Eldritch Knight. You recognize its War Magic Bonus Action, and Force Cannon action.
(25+) Machine of War. You know its strongest and weakest saving throws.
Combat Tactics
The Aetherian Sentinel targets the physically strongest creatures on the field first, and begins to work its way down in priority from there. Typically it begins its first turn of combat by casting Mirror Image, and activating it's Defensive Field bonus action before attempting to close the distance to its first target. On its second turn it begins it's onslaught of attacks with it's Radiant Blade, or Thunder Gauntlets within short range. If the target is out of range for the Thunder Gauntlets the Aetherian Sentinel instead uses its Force Cannons instead. When faced with enemies that pose a significant threat, the Aetherian Sentinel instead uses its second turn to cast Haste on itself and activate it's Radiant Aura if in dark lighting. It uses its Reactive Field reaction only on the physically weakest targets on the field, and uses it's Radiant Retaliation on melee combatants to impose disadvantage.
Lair and Lair Actions
While within the city of Aetherfall the power of the Aether Guard is at its pinnacle. Powered by one of the city's three Mythallar, the Aether Guard act as the first and primary line of defense against outside threats. Split into three distinct companies the faction uses both their armaments and the city itself as a weapon against their enemies, and are known to be brutally effective. Each company has unique lair actions specific to them as depicted below.
Lair Actions
On initiative count 20 (losing initiative ties), the Aetherian Sentinel takes a lair action to cause one of the following effects; the Aetherian Sentinel can’t use the same effect two rounds in a row:
-
Warding Aegis. The Sentinel's armor projects arcane barriers throughout the battlefield. The Sentinel creates up to 3 translucent walls of force, each 10 feet long, 10 feet high, and 1 foot thick, anywhere within 60 feet. These barriers have an 15 AC, and 25 hit points. They are immune to psychic damage, and provide total cover. They last until destroyed, or until the next initiative count 20. The Sentinel can see and make ranged attacks through these barriers without penalty.
-
Synchronized Reinforcement Protocol. The Sentinel's armor broadcasts a priority signal. 1d4 Aetherian Guard constructs (use Gargoyle statistics) emerge from hidden alcoves or materialize from nearby armories. They appear within 30 feet of the Sentinel and act immediately after this lair action. They disappear after 1 minute or when reduced to 0 hit points.
-
Gravitational Anchor Deployment. Ancient defensive enchantments woven into the city's foundation activate. The Sentinel chooses a point within 120 feet. All creatures within 20 feet of that point must make a DC 15 Strength saving throw. On a failure, they are pulled 15 feet toward the center and knocked Prone. Flying creatures fall if they fail the save. The area remains a gravitational anomaly until the next initiative count 20.
