This is my little pack with two spells (both are grenades)
-Radiation grenade : i think it's look great, it's make big aura of deadly radiation, just wait a while and aura is smaller,smaller,...
-Cluster grenade : naah, it's look...ehm...some bad, but it's only for effect

These spells are nearly without triggers, veeery easy to make and can be good usuable in multiplayer maps (these spells can be casted more times at once).
ENJOY! plz give credits to me, if you use my spells in your map
