Ok here are a few ideas that would make rpg and war better
Moltov roostertail
A beer bottle filled with gasoline and hair spray a flaming cloth sticking out of the top.
Explodes in fire when thrown.
kind of like this

Slime grenade
1 use until sime is dead.
a clear grenade that explodes in a ball of slime. it eats other players. it grows bigger after every kill (can only grow to a certain heigth).
net gun
a black gun with 4 little poles sticking out of the front and a net tied to it.
when it hits a player it traps them for about 10 seconds
flaming sword
a sliver and gold sword with a blue and orange flame emmiting from it
script requests
lich form
/lich activates it
/beblockhead deactivates it
turnes you into a lich and when you use your weapon a skeleton minion is created and attacks the enemy. up to 10 minions can be created

/killplayer (player name)
a super admin only power which allows him to kill the person of his chioce. can only be used every 2 minuets
