The Holy Hand Grenade was the most prized possession of King Arthur. How it came to you, only history knows.

Before you lob thy Holy Hand Grenade, you must recite the following; “And Saint Attila raised the hand grenade up on high, saying, 'O Lord, bless this thy hand grenade, that with it thou mayst blow thine enemies to tiny bits.' And the Lord did grin. And the people did feast upon the lambs, and sloths, and carp, and anchovies, and orangutans, and breakfast cereals, and fruit bats…”

“Skip a bit brother”

“And the Lord spake, saying, ''First shalt thou take out the Holy Pin. Then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then lobbest thou thy Holy Hand Grenade of Antioch towards thy foe, who, being naughty in My sight, shall snuff it.”

After reciting that, you must remove the Holy Pin. Then, you must count to 5. No, 3. 

The Holy Hand Grenade counts as a thrown weapon for the purpose of attack rolls, and adds a +3 bonus to attack rolls as well. It has a range of (150/1000). 

The Holy Hand Grenade of Antioch explodes in a Hollywood-style fireball the instant it makes contact with the target, or any other surface. Any creature within a sphere with a 20 foot diameter centered on the grenade takes 3d10 fire damage and 6d10 force damage. The explosion also sets objects that are not being worn aflame.
