Imagine this... you want the - Chrono Cross
Imagine this... you want the Mastermune, the best sword in the game (although the Spectral Swallow has a higher power the Mastermune will make a critical hit on fierce level attacks almost every time).
It's easy to find it. The problem is how to get it. To find the Mastermune you have to go to Island of the Dammed with Karsh on your party, in the Other World.
Head to Garai's Grave, you'll fight Solt & Peppor (steal some elements from them, I forgot wich... yellow elements i think) after that you'll recieve the Mementopendant.
After that, go to Home Worls and head to Forbidden Island. Don't know where that is?? It's a small island to the east of Mt. Pyre (where smoke comes out), aproach it at press the action button.
With Riddel on your party enter the hut and you'll find... Dario. After a few scenes, the Mastermune will appear and Dario will go berserk.
Fighting time... To beat Dario you'll have to ways. Either you equip the black plate on one character so he doesn't hurt you.... but if you didn't steal it or didn't fight the Black Dragon then you'll need a new strategy.
The secret is in it's attacks. Every time you hit im with a White, Yellow, Blue, Black element he will either attack you or heal himself.
But if you only use Red and Green Elements he will only cast Lo-Res and Nimble. Keep in mind you'll need all your grids with elements of these colour since he has a high HP.
I equiped all my characters with only Aeroblasters. After about 15 min. he will fall and Masa & Mune will awake and combine with your Sea Swallow to form the Martermune...
Congratulations, you are now the owner of the ultimate sword for Serge (although I beat Dario when I was still Linx)
