The Earth Vellumental is your first major Vellumental boss. It's a large, rock-like creature that primarily uses ground-pound attacks. Phases: The battle starts with the Vellumental in its normal form. It will occasionally retreat into its shell, becoming invulnerable to direct attacks. Weaknesses: Its main weakness is its exposed head when it's not in its shell. The 1,000-Fold Arms ability is crucial here. Strategy: Focus on aligning the rings to create a path to the 'ON' panel, which activates the 1,000-Fold Arms. Use the arms to grab and slam the Vellumental, flipping it over. While it's flipped, use your most powerful Jump attacks. When it's in its shell, use the 'Magic Circle' panel to activate the Earth Vellumental's own power (once you've acquired it) to force it out. Keep healing with Mushrooms if needed. Rewards: Earth Vellumental power, access to the Red Streamer boss.
