RUBY WEAPON

They're two easy strategies to beat Ruby weapon. One which works on Emerald Weapon.

Send one character in againist Ruby and have him cast the following spells. First cast Hades on the body of Ruby Weapon, then cast KotR on the tenticles. From then on just mime the spells as Hades will freeze your opponet and Kotr will restore your HP and deal out massize damage.

The next strategy which also works on Emerald Weapon is just as easy as the first. Send one character in again and have him W-Summon Kotr two times. One on the claws one on the body. As long as your HP is 9999 you have nothing to fear from the mighty weapon.

EMERALD WEAPON

For an easy strategy just check out the 2nd Ruby Weapon strategy.

If you want a strategy that works even quicker though send on character in with 7777 fever. He'll do about 500,000 points of damage. Then have your second character W-Summon Kotr for about 200,000 more points of damage. Have your third character mime Kotr again for 200,000 more points of damage. All you have to do is mime KotR one more time to defeat the mighty Emerald Weapon.
