Ark

[SilverWolf14]

how in the hell do you get Ark the summon????
all i know is that you need 2 pumice pieces and a hammer wheres the hammer at?????

[mooglebunni608]

I think the hammer comes from getting all the stallazios and giveng em to the bird lady in treno... duno about the pummice pieces tho

[Flying Mullet]

You have to buy it in Memoria. I forget the name of who sells it to you, but you find them hidden from view behind some rocks/coral in Memoria.

EDIT: Yeah, I think that's where you get the hammer. Maybe it's the other pumice piece you buy?

[Quindiana Jones]

Hades, the master synthesiser. You can get 4 Pumice Pieces in total I think. Or it might just be 2. I know you get one of Ark when you fight him, and when of Ozma. But I think there's more. Hades is in the sea-y coral rocky place. Just walk rightish and you'll find a "!". Talk to it and you fight Hades. Beat him and he synths stuff for you. Like Tin Armour and Pumice. Pumice teaches you Ark. Tada!

[Necronopticous]

You do not need the hammer to synth a pumice, only two pumice pieces. There are a few pumice pieces in the game, the ones you'll probably want to go for are:
Spoil from beating Ark in Oeilvert.
One of the items in the Outer Island 2 chocograph treasure.
When you have the ingredients, beat Hades in Memoria and he'll synth it for you. You can also synth Save the Queen here for 50,000 gil, a javelin, and a pair of silver gloves. Both the hammer and Save the Queen sword are simply for bonus material in the ending. The only synthesis that consumes the hammer is the tin armor and the pumice piece.

If you want the hammer, find and give all the Stellazios to the woman in Treno and you'll be rewarded with it.

Here are the locations of the Stellazios:
Aries - Dali's Windmill.
Taurus - Behind Treno's item shop in the slums
Gemini - Throw 10 gil into the fountain at Treno's entrance 13 times.
Cancer - Behind the overturned cart near the entrance of Burmecia.
Leo - Near the statue of Neptune that transports the party to Alexandria Harbor.
Virgo - In Black Mage Village's Inn.
Libra - Right side of Madain Sari's fountain.
Scorpio - Below the HP/MP restoring spring in Quan's Dwelling.
Sagittarius - Left of the Gysahl Pickle cart in Lindblum (during reconstruction).
Capricorn - In the waters to the right of the entrance to Daguerreo.
Aquarius - Right hand chest at the entrance of Ipsen's Castle.
Pisces - Chest inside the Invincible airship.
Ophiuchus - Collect all 12, then search where Scorpio was found.

You can get one whole Pumice from Ozma, and one Pumice Piece. One of them can be stolen, the other one is achieved after battle. I don't remember which of them is gotten which way.

[J.Raven]

A bit off topic, but on getting the hammer, there was only one additional scene you can get in this whole game, right? The part in the play where Baku 'slays' Blank because he thinks if Blank can betray Marcus, he can betray the king himself.

[Rantz]

J.Raven, that's correct.
