Challenge Override! 65 (1.600.000 XP)

Pilotable. The Battle-Armor can be piloted by a small medium or large humanoid creature in which case it uses the pilots INT and CHA score and saving throw. The pilot is locked inside the Battle-Armor and becomes untargetable by spells and attacks. If the Battle-Armor Dies the pilot will be expelled by the construct.

Inert. When not piloted the Battle-Armor becomes inert and cannot take any turns. If the Battle-Armor becomes inert while wielding the Lit Plane-Render Glaive the glaive becomes Unlit and inert.

Huge^2. The Construct is immune to any spell or effect that would alter its form. It take up to two size huge templates on the battlefield on for each foot. Each template has a move and fly speed of 240 ft. but must always end its turn on the ground. 

Magic Resistance. The construct has advantage on saving throws against spells and other magical effects.

Overwhelming attacks. The constructs weapon attacks are magical and adamantine in order to overcome immunities and resistances and deals double damage to buildings and structures. 

Plane-Render Glaive. The construct wields a size gargantuan glaive. The pilot of the  construct can as an action cast a free wish spell but only with the objective of lighting the Plane-Render Glaive giving it the Lit keyword. The pilot suffers the usual consequences of the wish spell. If the Plane-Render Glaive is not being wielded by a Adamant God-Slayer Battle-Armor it will become Unlit after 10 minutes.

Any creature wielding the Plane-Render Glaive can perform the Plane-Render Glaive Swipe and Plane-Render Glaive Stab as an attack action. Without piloting the God-Slayer Battle-Armor only a normal wish spell can be used to light the Plane-Render Glaive.

Lit Plane-Render Glaive. A weapon attack with a Lit Plane-Render Glaive deals an additional 2d20 fire damage and 2d20 lightning damage. If the target is size huge or above and the attack only targets that creature it deals and additional 7d20 fire damage and 7d20 lightning damage and the weapon attack damage dice is doubled.

A creature that wields the Lit Plane-Render Glaive that also has legendary actions can use one of the following legendary actions instead.

1. Void-Ripper (costs all Actions). The wielder can expend a legendary action to at will tear open a Gargantuan portal to any plane of existence or any location beyond 9000 ft. The portal lasts 1 hour upon which it collapses.

2. Chasm of Destruction costs 2 Actions. The wielder can expend one legendary action to at will tear open a chasm into a chaotic unknown plane of any chosen damage type for 1 minute. The chasm must start within 40 ft. of the wielder and is 30 ft. wide, 600 ft. long, is difficult terrain and requires a DC 16 Strength or Dexterity saving throw to crawl out of. Any structures and natural obstacles without special resistances that stands in the chasm collapses into the chosen plane and is destroyed.  For each turn a creature is still in the chasm the creature takes 20d8 damage of the planes chosen damage type.

Multiattack. The construct makes 3 melee attacks and attempts to shoot each of its Star-Dragon cannons.

Last stand.  When the construct drops bellow 1000 HP it can no longer make ranged weapon attacks and gains a -5 to hit modifier but it can now make 5 melee attacks per turn.

Stomp. Melee Attack:  reach 20 ft., one target (Size large or bellow). Each creature in a 15-foot-radius sphere centered on the target must make a Dexterity saving throw or take 4d8 non-magical bludgeoning damage and 2d20 force damage.

Any other creature in this cone must succeed a DC 18 dexterity check or take 2d20 force damage.

Twin Star-Dragon Cannons (2 recharge 4-6). Each cannon shoots 4 balls of blinding energy 20-foot radius spheres originating from a visible point within 1600 ft. Each creature in that area must make a DC 14 Dexterity saving throw, taking 60 (10d8 + 15) radiant damage and 60 (10d8 + 15) fire damage on a failed save, or half as much damage on a successful saving throw, or no damage on a roll of 19 or 20.

The Adamant God-Slayer Battle-Armor can expend 1 legendary action as a reaction, choosing from the options bellow.

1. Absorb Spell. If the Adamant God-Slayer Battle-Armor succeeds a saving throw against a spell, the spell is absorbed so no damage from that specific spell is taken on a succeeded save until the end of its next turn.

2. Counter Seige. When the Adamant God-Slayer Battle-Armor looses any health to a siege weapon one of its Star-Dragon Cannons recharges and can be fired.

3. Brace.  When the Adamant God-Slayer Battle-Armor is hit by a weapon attack it can brace itself increasing its AC by 2. This does not stack.

The Adamant God-Slayer Battle-Armor can take 4 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The Adamant God-Slayer Battle-Armor regains spent legendary actions at the start of its turn.

4. Void-Torpedo (Costs 4 Actions)(recharge 5-6). The Adamant God-Slayer Battle-Armor hurls the Lit Plane-Render Glaive at a target within 1200ft. The targeted creature must succeed a DC 20 Dexterity saving throw or be impaled into the ground, becoming restrained. If the target is large or smaller it is simply knocked prone and only takes half damage. On a failed save the target takes 550 (100d8 + 100) piercing damage and 120 (10d20+15) force damage. If a target is killed by this attack its soul is banished into an unknown demi-plane or destroyed at will. If the soul is destroyed each creature within a 120-foot radius sphere must make a dexterity 17 saving throw or take 42 (4d20) force damage.
