Colossification

9th Level Transmutation

• Casting Time: 1 action
• Range: Touch
• Components: V, S, M (your familiar)
• Duration: 8 hours

Touching your familiar and gently whispering words of power, you make it grow to incredible proportions. It gains the following benefits while the spell lasts. If your familiar is not in the form of an animal (such as an imp), casting this spell requires 5,000 gp worth of diamond dust as an additional material component which is consumed.

• It becomes Gargantuan. If there isn't enough room for it to increase size, it makes a Strength check to break through the surrounding material. It otherwise attains the maximum possible size in the space available.

• Its current and maximum hit points increase to 200.

• Its Strength and Constitution scores increase to 26.

• It can take the Attack action.

• Its reach becomes 15 feet.

• If it already has an attack, that attack now deals 34 (4d12 + 8) damage.

• It can perform a bite attack that deals 34 (4d12 + 8) piercing damage. A bitten creature is grappled (escape DC 20). Until this grapple ends, the target is restrained, and your familiar can't bite another target.

• It has advantage on Strength checks and Strength saving throws.

• It adds your proficiency bonus to its attack rolls, Strength checks, AC, and saving throws.

"MEOW," it said, and the earth trembled.

• As an action, it can make one bite attack against a Large or smaller creature it is grappling. If the attack hits, the target takes the bite's damage, the target is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside the familiar, and it takes 28 (8d6) acid damage at the start of each of the familiar's turns. If the familiar takes 30 damage or more on a single turn from a creature inside it, it must succeed on a DC 20 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the familiar.

• Its attacks deal double damage against objects and structures and count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

• It becomes immune to being charmed and frightened.

• Once during the spell, it can choose to succeed on a saving throw.

• It does not disappear when reduced to 0 hit points. Instead, it makes death saving throws like you do. It disappears if it has three failed death saving throws.

• It ignores difficult terrain as it simply powers through it.

While affected by this spell, your familiar cannot be dismissed and then resummoned. If any creatures are inside it when the spell ends, they fall prone within a space which the familiar previously occupied. You can end the spell early as an action.

Pact of the Chain warlocks cannot forgo one of their attacks when they take the Attack action to allow their familiar to make one attack with its reaction while it is affected by this spell. In addition, if they have the Investment of the Chain Master invocation, they cannot use a bonus action to command the familiar to take the Attack action while it is affected by this spell.
