Titanic Rig

The Titanic Rig is incapacitated without its Pilot. If it is forced to make an Intelligence, Wisdom, or Charisma ability check or saving throw, its Pilot is considered to be the target of the effect instead.

Moreover, when the Pilot is concentrating on a spell when the Titanic Rig takes damage, the Pilot must make its Constitution saving throw to maintain concentration as if the Pilot had taken that damage.

The Titanic Rig can choose to ignore any spell or effect that would alter or change its form.

When the Titanic Rig takes damage, it reduces the damage by its Constitution modifier (4). Acid and force damage bypass the effects of this feature.

The Titanic Rig's weapon attacks and spells deal the maximum possible damage, in place of rolling, when used on non-magical objects and structures.

Melee Weapon Attack: +6 + PB to hit, reach ft., one target you can see. Hit: 3d6+6 bludgeoning damage.

The Titanic Rig becomes Huge in size, so long as there is room for it to grow. While it is Huge, its Slam attacks deal an additional 1d6 damage on hit, its reach increases by 5 ft., and it adds your INT to all Strength ability checks and saving throws.

This transformation lasts for 1 minute. It ends early if the Titanic Rig is destroyed, or its Pilot uses their action to cause the Rig to revert to its normal form.

The Titanic Rig can transform in this way once, and it regains the ability to do so at the following dawn. When it has no uses left, its Pilot can expend a 5th-level spell slot to use this transformation again.
