Air Form. The elder tempest can enter a hostile creature’s space and stop there. It can move through a space as narrow as 2 centimeters wide without squeezing.

Legendary Resistance (3/day). If the elder tempest fails a saving throw, it can choose to succeed instead.

Living Storm. The elder tempest is always at the center of a storm 2d6 + 5 kilometers in diameter. Heavy precipitation in the form of either rain or snow falls there, causing the area to be lightly obscured. Heavy rain also extinguishes open flames and imposes disadvantage on Perception checks that rely on hearing.

In addition, strong winds swirl in the area covered by the storm. The winds impose disadvantage on ranged weapon attacks. The winds extinguish open flames and disperse fog.

Maneuvers. The elder tempest uses maneuvers (maneuver save Difficulty 24). It has 22 stamina dice which are d8s, a dice limit of 8, regains all expended stamina dice when it finishes a long rest, and regains half its total stamina dice when it finishes a short rest. It knows the following maneuvers:

1 stamina die: dive attack, spring attack, step of the wind

Siege Monster. The elder tempest deals double damage to objects and structures.

Spellcasting. The elder tempest uses Primal (cha) to cast spells (spell save Difficulty 20, +11 to hit with spell attacks). It has 11 mana, a mana limit of 4, regains all expended mana when it finishes a long rest, and regains half its total mana when it finishes a short rest. It knows the following spells:

Cantrips (at will, 29th-level spellcaster): lightning lure, shock, thunderclap

1 mana: arc lightning, booming weapon, conduit, galvanize, lightning bolt, protection from the storm, shocking weapon, storm burst, thunder step, thunderwave, wrath of the storm

2 mana: animate storm, call lightning, chain lightning, lightning strike, rolling thunder, shatter, storm bane, storm sphere

3 mana: symbol of stunning

Actions (2)

Thunderous Slam. Melee Weapon Attack: +15 to hit, reach 4 m. Hit: 23 (4d6 + 9) concussion damage.

Legendary actions (3)

Only one legendary option can be used at a time and only at the end of another creature’s turn. The elder tempest regains spent legendary actions at the start of its turn.

Lightning Strike (Costs 2 actions). The tempest can cause a bolt of lightning to strike a point on the ground anywhere under its storm. Each creature within 1 meter of that point must make a Difficulty 20 Reflex saving throw. On a failure, a creature takes 16 (3d10) lightning damage, and it can’t take reactions until the start of its next turn. On a success, a creature takes half as much damage.

Move. The tempest moves up to its speed.

Screaming Gale (Costs 3 actions). The tempest releases a blast of thunder and wind in a line that is 2 kilometers long and 5 meters wide. Objects in that area take 22 (4d10) concussion damage. Each creature there must succeed on a Difficulty 21 Reflex saving throw or take 22 (4d10) concussion damage and be flung up to 10 meters in a direction away from the line. If a thrown target collides with an immovable object, such as a wall or floor, the target takes 3 (1d6) bludgeoning damage for every 2 meters it was thrown before impact. If the target would collide with another creature instead, that other creature must succeed on a Difficulty 21 Reflex saving throw or take the same damage and be knocked prone.

M (mercury, phosphorus, and powdered diamond and opal worth 1,000 sp, consumed)

As you spend 1 minute to cast this spell, you inscribe a harmful glyph either on a surface (such as a section of floor, a wall, or a table) or within an object that can be closed to conceal the glyph (such as a book, a scroll, or a treasure chest). If you choose a surface, the glyph can cover an area of the surface no larger than 2 meters in diameter. If you choose an object, that object must remain in its place; if the object is moved more than 2 meters from where you cast this spell, the glyph is broken, and the spell ends without being triggered.

The glyph is nearly invisible, requiring a Perception check against your spell save Difficulty to find it.

You decide what triggers the glyph when you cast the spell. For glyphs inscribed on a surface, the most typical triggers include touching or stepping on the glyph, removing another object covering it, approaching within a certain distance of it, or manipulating the object that holds it. For glyphs inscribed within an object, the most common triggers are opening the object, approaching within a certain distance of it, or seeing or reading the glyph.

You can further refine the trigger so the spell is activated only under certain circumstances or according to a creature’s physical characteristics (such as height or weight), or physical kind (for example, the ward could be set to affect hags or shapechangers). You can also specify creatures that don’t trigger the glyph, such as those who say a certain password.

Once triggered, the glyph glows, filling a sphere twice as big as normal with dim light for 10 minutes, after which time the spell ends. Each creature in the area when the glyph activates must succeed on a Fortitude saving throw or be stunned for 1 minute.

A creature must also make this saving throw when it enters the spell’s area for the first time on a turn or starts its turn there.
