Ok listen up. I've done the Holy Hand Grenade quest and it is a success. This is how it goes:
Go to EW, and around 110,-789, you should stumble upon a trap, which appears to be a frozen bush.
You look around the bush and find a party of knights.
There are 3 knights here. Their names are Tim, Arthur, & Robin. Hail Tim and he says this.
Tim says,'Shh there! And fix our bush! Were trying to hide from...... it....'
Robin says,'What Tim means is that IT is a rabbit and-'
Tim says,'SHHH!!! That name isin't sacred here! It devoured Boris!'
Arthur says,'Like Robin was tring to say, this rabbit overthrew our party of 4. We were told that this rabbit was a foul beast that lived in some cave not far from right here. We didnt think it was a rabbit when the king told us what it was. We ventured into the caverns, Robin soiled himself, this rabbit devoured Boris, our friend, and we ran out over here. We've been hiding ever since. We were told to use the [Holy Hand Grenade] to kill the rabbit, but it was too late.'
Tim says,'Poor Boris! He was too foolish! He didn't listen to my warning!'
Tim mourns over the loss of Boris.
You say,'What Holy Hand Grenade?'
Arthur says,'Well the Holy Hand Grenade is supposed to be the only weapon that can destroy the rabbit. You have to throw it at the right time, but if you dont throw it right, the rabbit may have an easy target. If you want, I can give it to you, but you must [vanquish the Rabbit] first.'
You say,'I will vanquish the Rabbit.'
Tim says,'You speak foolishly, young one! Noone can vanquish the rabbit!'
Arthur says,'Let him try Tim.'
Robin says,'Well, I have an Extra Holy Hand Grenade left. I can give it to you. Take this, and vanquish the Rabbit. Quckly hurry!'
At this point, you find the ultimate weapon:
The Holy Hand Grenade. Magic, No Drop, Lore

Robin says,'To activate the Holy Hand Grenade, you must..... well..... Count to three, leave out 2, and in it's place put the the # after 3. The Holy Hand Grenade should activate and vanquish the creature.'
Tim says,'Quiet, the rabbit's cave is just south of here, if it hears us plotting, It'll vanquish US!'
A few feet away from the cowardly adventurers is a small cave. You have to duck or get a shrink to enter (Halflings and shorter dont have to duck to enter). Once inside, crawl for a few more feet, then the caves get bigger. Go forward until you reach the bones of four horses, then you should see 3 caves, and a pair of footprints heading for the one to the right. Follow the cave until you reach a large room. This is the Rabbit's Lair. Once you enter, there should be a trap.
You step into the room, and a small rabbit crawls out of a hole.
Now it's just a normal snow bunny currently, but wait 5 seconds. You should see another trap.
The rabbit approaches as a sense of fear overcomes you. If you dont throw the grenade now, it will attack. It does a hefty 1750 dmg max, so you could die quite quick. Follow the riddle that Robin told you. I did this (Be sure to target the rabbit)
You say,'One'
You say,'Four'
You say,'Three!'
Your Holy Hand Grenade starts to shake.
Holy Hand Grenade says,'HALLEYUA!'
Now a large sparkle flies from you to the rabbit.
A Snow Bunny has been hit by non-melee for 5000 damage!
A Snow Bunny has been hit by non-melee for 5000 damage!
A Snow Bunny has been hit by non-melee for 5000 damage!
A Snow Bunny was hit for non-melee for 90000 damage!
A Snow Bunny feels the true power of the Holy Hand Grenade!
You have slain a snow bunny!
You gain experience!
Now loot it and it should have one thing:
Blessed Snow Bunny Pelt.
Take it and wait 5 seconds.
An injured man crawls out of a pile of rocks.
His name is Boris and is the lost knight that the other 3 were talking about.
You say,'Hail, Boris'
Boris says,'Thank the king for you! You slew the rabbit! But.... how? Did you use the Holy Hand Grenade? A small explosion woke me... so....'
You say,'I used the Holy Hand Grenade'
Boris says,'That means.....you have spoken to the others! Please [escort] me to them, if you can.'
You say,'I will escort you.'
Boris, exited, squeals, then says,'Great, let's go!'
It's an easy escort to do. There is barely anything on the path but maybe the occasionaly Ry'Gorr or Frost Giant. Escort him over to the knights, then get your great present.
Tim says,'Boris! Your alive!'
Robin says,'Well, throw me a Snow bunny, your ok!'
Arthur says,'Amaizing! But how?'
Arthur begins to cast a spell
Boris says,'This brave adventurer used the Holy Hand Grenade to kill the rabbit and-'
Boris is completely healed.
Arthur says,'No I meant how did you survive te rabbit.'
Boris says,'It chewed me a few times, didn't like my taste, and threw me into a pile of rocks.'
Tim says,'Oh.'
Robin says,'Well, congradulations Nindail. You killed the rabbit, rescued our friend, and saved us also. But I wonder what happened to the rabbit.'
I handed Robin the pelt.
Robin says,'Oh my! The Holy Hand Grenade blessed the rabbit's fur! And it slaughtered the rabbit into a billion pieces! Wow! Here you go. I think it may be useful. It can create Holy Hand Grenades once every 5 hours. Enjoy! C'mon guys, let's go.'
All four of the knights despawn now, and in your inventory slot, you find something odd, but great.
Holy Grail Magic, Lore, No Drop
Wt: 1.0

The grail is a right click to summon a Magic, Lore, No Drop, No rent copy of the Holy Hand Grenade.
Awesome quest, you can solo it all, no min or max lvl (All you need to do is get to the Knights & bunny). Out of 1 to 5, I give this quest a 17.
