You'll need to add some stuff to your config if you want to change the cooldown &/or edit the message.
Just tack the following section onto the end of your config file:
Code (YAML):
# How long between each use of a totem? (in seconds) Cooldown: 60
# Message to send to the player when totems are on cooldown. TotemOnCooldown: "&cTotems have been put on cooldown for {0} seconds!"
