The Deluge of Grulovia

You will start back on the Forgetful Forest path, which now features swirling whirlwinds you must evade by timing your jumps between high points.

An Otto-matic (a shop where you can buy items) will fall onto the path nearby, offering a chance to restock on healing items or buy pins (collectible badges that grant abilities).

Proceed farther until you reach new surroundings.

Examine the statue and use mental connection (a psychic ability to interact with minds and objects).

In the next area, examine the statue again and use mental connection to proceed.

Burn the Maligula tapestry located to the left of the bed.

Use mental connection once more to continue.

During the fight, Maligula will summon water snakes and send them towards you. Dodge them as they pause and rear up near you.

Maligula might also form a waterspout and rush around the battlefield; this attack is harder to dodge and can knock you off the platform, causing damage.

While dodging, use psi blast (a psychic attack) to gradually reduce Maligula's health.

When Maligula's health is about a fourth down, doubts will appear and require your attention.

Your allies' attacks may occasionally stun Maligula.

Around the halfway health mark, the fight mechanics will revert to how they were at the start.

When Maligula has about a third of her health remaining, bad ideas will appear that you must deal with while still dodging water snakes.

When Maligula has about a sixth of her health left, a new phase of the fight begins.

Your objective in this phase is to drive Maligula back a certain distance.

Punch Maligula when she is vulnerable.

Use your breath attack (a psychic ability) when she is charging a water attack.
