I have included the following:
Gold Shower, spawns piles of gold.
Token Shower, spawns piles of tokens (note: this is based on OWLTR and the Tokens are named Daat99Tokens, this may need to be changed for your shard)
Mixed Shower, spawns a mixture of gold and tokens at a roughly 50/50 rate but it is of course random.
The command can be used as follows:
[(Gold/Token/Mixed)Shower NumberOfPiles MinimumAmountPerPile MaximumAmountPerPile Radius
