Path of the Titan

Same thing as the short desc. This is a kaiju-based subclass I put onto D&D Beyond for everybody to use in their Godzilla-themed campaigns. Original content made by chaoskings35 on Reddit.

Titanic Might

Starting at 3rd level, when you rage, you can choose to grow one size larger. If you do so and there isn't enough room for you to double your size, you attain the maximum possible size in the space available for the duration. Once on each of your turns, one of your attacks with a weapon or an unarmed strike can deal an extra 1d6 damage to a target on a hit.

Monkey Fist

Also starting at 3rd level, your unarmed strikes do 1d6 + your Strength modifier bludgeoning damage. This damage increases to 1d8 at 6th level, 1d10 at 10th, and 1d12 at 14th. Additionally, when you are hit by a melee attack while raging and you have a free hand, you can use your reaction to attempt to grapple that creature so long as they are within 5 feet of you.

Titanic Blows

Beginning at 6th level, when you are raging and hit with an unarmed strike on your turn against a creature you size or smaller, you may use one of the following Titanic Blows options of your choice. The creature must make a strength saving throw. The DC for this saving throw is equal to 8 + your Strength modifier + your proficiency bonus. You can only use one Titanic Blow option per turn. 

Hammering Blow. A creature is knocked prone on a failed save, or has its movement speed reduced by half on its next turn on a success.

Launching Blow. A creature is knocked back 30 feet on a failure, or 10 feet on a success. This movement does not provoke attacks of opportunity.

Run Down

Starting at 10th level, so long as you move at least half your full speed towards a creature, and you have a free hand, you can use your bonus action to attempt to grapple or shove them.

Additionally, you are no longer slowed when carrying a grappled creature while enlarged by your Titanic Might feature.

Titan of Wrath

Starting at 14th level, when you rage and choose to grow one size larger using your Titanic Might feature, you can choose to instead become Huge sized. You can do this only once per long rest. While enlarged in this way, you gain the following benefits which replace those from your Titanic Might.

 Titanic Destruction. You deal double damage to objects and structures.

Titan's Grasp. When you grapple a creature, they are considered restrained if they are at least two sizes smaller than you.

Titan's Strength. Each of your attacks deal an extra 1d6 damage.
