Kikuichimonji

The Kikuichimonji is a Light Blade found in Golden Sun. It is dropped by Fenrirs in Venus Lighthouse, although the odds of receiving one are very slim. Being a Light Blade, it can be equipped by Isaac, Felix, Garet, Jenna, Ivan, and Piers. It increases the wielder’s attack by 128, making it both the most powerful Light Blade and second most powerful weapon in Golden Sun. It can be bought for 13400 coins and sold for 10050 coins.

The Kikuichimonji's Unleashed power is Asura (Shura no Mai/Dance of Ashura in Japan). It converts all damage to Jupiter damage and attacks with an additional 64 attack points. It also has a chance of ignoring 50% of the target's defense, increasing the amount of damage done.

The Kikuichimonji is a rare but powerful weapon with few rivals to speak of, outdone only by the Gaia Blade in terms of attack power. However, there are other weapons that can challenge its position, most notably the Swift Sword. Although physically weaker, the Swift Sword's Unleash, Sonic Smash, occasionally triples the damage done, which can overpower even the Gaia Blade. Sonic Smash also does Jupiter damage, and the Swift Sword increases the wielder’s Jupiter power, making it seemingly the perfect weapon for Ivan. Similar attributes make the Gaia Blade suitable for Isaac, meaning only Garet is likely to possess a Kikuichimonji in the game's finale (and probably only if he is a Conjurer, Ninja, or Samurai). However, all these weapons are found late in Golden Sun and can easily be outdone in Golden Sun: The Lost Age, so their usefulness is somewhat limited.

RNG Methods

 * Main article: Random Number Generator

This is a method for obtaining the Kikuichimonji. Make sure the agility of your party members goes from Ivan, Isaac, Mia, Garet. You can do this by equiping Running Shirts, Ninja Garb, Ninja Hood, Elven Shirt, Kimono, or Feathered Robe. Go to the main room in Venus Lighthouse (the one with the Psynergy Stone in the middle). Save and turn off the GBA completely. Turn it on again and run around the room to engage in a battle. It should be against an Ice Gargoyle and a Fenrir. On the first round, have Isaac use Clay Spire (big arrow to the Fenrir). Have Garet use Flare Wall (big arrow to the Fenrir). Have Ivan use Tornado (big arrow to the Gargoyle). Have Mia use Ice Horn (big arrow to the Gargoyle). The Gargoyle should die. On the next round, have Isaac defend, Garet use Torch, Ivan defend, Mia use Wish. This should drop the Kikuichimonji.
