Godsword
From Runescape Guides & Runescape Tips
The Godsword is the strongest class of weapon in the entire game, by far. It is a two-handed sword. The pieces that must be assembled to create the mighty godsword are dropped by monsters in the God Wars Dungeon. The Godsword blade is generic for all the swords and are valued at 6-9 million. The first step to creating a godsword is to recreate the godsword blade. To do this, you must smith together Godsword shard 1, Godsword shard 2 and Godsword shard 3. To do this, you must have a smithing level of at least 80. You receive 200 experience for attatching together the shards to create the blade.
The unique things about godswords are the four different types of hilts. The hilts are the Saradomin Hilt, Zamorak Hilt, Armadyl Hilt, and the Bandos hilt. These hilts, when attatched with the godsword blade, create a weapon that has a unique special ability, depending on what hilt was used. The hilts are much more rarer and worth up to several 10s of millions. Attatching different hilts do not require any smithing pre-requisiite. You can dismantle the godsword and then attatch a new hilt to it. This means that all you need is 1 godsword blade and you can swap between hilts. The different hilts will give you different special attacks which can be good is specific occasions.
Armadyl Godsword: Inflicts 25% more damage and drains 1/2 of the opponent's special attack bar
Saradomin Godsword: 1/2 of the damage you deal returns to your health while 1/4 of the damage you deal returns to your prayer. No matter what you get 10HP and 5 Prayer back, at least. Also, 1/2 of your opponent's special attack bar is drained.
Bandos Godsword: You drain your opponent's stats depending on the damage you inflict. You drain their defense first, then strength, then prayer, then attack, then magic, and finally ranged. Their entire special bar is drained.
Zamorak Godsword: Freezes your opponent for 20 seconds and drains 3/5 of your opponent's special attack.
