You can add scripts to your totems using Kether. The scripts will run when a player uses the totem.
Example
scripts: - 'player allow flight to true' - 'player fly speed to 0.1' - 'tell color "&7You can fly now!"' - 'sleep 10.0s' - 'player allow flight to false' - 'tell color "&7You can not fly anymore!"'
This will allow the player to fly for 10 seconds, with a speed of 0.1 upon using the totem. After the 10 seconds have passed, the player will stop flying and fall to the ground.
You can do more advanced things; it all depends on your imagination. To learn about all the scripts you can use, go to the Kether documentation.
