Multiattack (Requires Druid Level 5+). You make two Rend attacks.

Rampager (Requires Druid Level 10+). You expend a level 1+ spell slot and move up to half your Speed without provoking Opportunity Attacks. When you enter the space of an enemy that is at least two sizes smaller than you for the first time on a turn, that creature is subjected to the following effect. Strength Saving Throw: DC equals your spell save DC. Failure: The target has the Prone condition. If the Target already has the Prone Condition, it instead takes 1d10 Bludgeoning damage.

Swallow (Requires Druid Level 14+). Strength Saving Throw: DC equals your spell save DC, while you are Gargantuan, a Large or smaller creature that is Grappled by you.

The number of creatures you can have swallowed at a time equals your Wisdom modifier (minimum of one creature). You must maintain Concentration to hold swallowed creatures in your stomach. If you lose Concentration or leave your Titan Form you regurgitate all swallowed creatures, each of which falls in a space within 10 feet of you and has the Prone condition.
