The Knight’s House is also known as the Weapon Shop in Treno. In addition to being able to purchase weapons from the Old Woman inside, you can also select another option when speaking to her to ask about the monster in the basement and initiate the battle.

Each of the monsters is similar to those found in the field, and they become available at different points in the game. You can only kill each of the monsters once and you have the option of selecting which party member will be involved in the battle. If you miss any of the battles listed below, you will not be able to go back and re-initiate the fight.

Griffin

This battle can be initiated on Disc 2 when you first arrive in Treno. Equip Steiner with the following items:

• Blood Sword (drains HP with every attack)
• Gold Choker (halves wind damage)
• Bird Killer ability (extra damage against the Griffin)

The items listed above make it a relatively easy fight—two or three hits max, even at lower levels. The reward for successful completion is a Tonberry Card.

Catoblepas

You can initiate this battle during the visit on Disc 3 during the card tournament sequence in Treno.

Equip Zidane with his newest weapon, Angel Bless, or go and Synthesize one in the Synthesis Shop (you can purchase the raw materials at other item/weapon shops in town).

Equip him with the Beast Killer and Jelly abilities to increase your damage and prevent the petrification status effect, as well as the Coral Ring accessory. The Coral Ring will cause Catoblepas’ thunder-based abilities to heal Zidane.

The reward for successfully defeating Catoblepas is 15,000 gil.

Amdusias

You can initiate this battle after obtaining Hilda Garde III on Disc 3 and returning to Treno before heading to Ipsen’s Castle.

Make sure to equip Zidane with his strongest weapon which should be the Sargatanas from Daguerreo and his strongest armor. The battle should then be pretty easy.

You can use the Bird Killer ability to make the battle easier and use the Auto-Regen ability to heal up from attacks. Amdusias has approximately 6,578 HP. The prize for defeating it is another pair of Running Shoes.

Behemoth

You can initiate this battle any time during Disc 4.

Make sure that you equip Zidane with the Auto-Regen ability and Auto-Haste ability and make sure that you cast Silence on it to prevent it from casting Meteor.

Alternatively, you can equip Zidane’s Sargatanas weapon and use the Soul Blade ability to Petrify Behemoth to make the fight even easier. The reward for defeating it is a Circlet.
