Liquid sword

The liquid sword is a very powerful weapon, requiring 95 Attack to wield. It is a very complex weapon as well. Being very powerful, it is also very expensive. Like items that must be recharged, this one must be recharged but in a different way. You must buy Liquid metal cartridges (Grand Exchange is cheapest) and dump it in the metal bottle. The day of the release, the bottle cost 3,000,000 but after a weeks time it skyrocketed to 46,000,000. The cartridges started at 5,000 but quickly rose to 112,000. You must finish Liquid Metal Foundation before this item is wieldable.

Use
This item starts out as just a bottle. It looks very similar to a water bottle. Obtaining the bottle is very expensive and if you train with it, you could use 5,000,000 a week just on cartridges. Once you have the bottle and a cartridge, You empty your cartridge in the bottle and you will then have a liquid metal bottle. Then turn your special on and a Liquid sword will rise out of the bottle. The liquid being the blade and the bottle being the hilt would be the bottle. Every one minute, 1% of your special bar is drained. This means if you do not use the special any, This sword may last 100 minutes until you need a new cartridge.

Special Attack
The special attack of this fabulous sword is called Liquid Spill. The sword goes back into the bottle and the user splasher 25% of the liquid on the other player. It drains 1 skill all the way down to level 1. This can be very handy in PvP as you could reduce one of their combat stats to 0 instantly (this includes Prayer, Constitution, etc.). This special may only be used in PvP.
