Setting enchantment type to 'REPEATING', you unlock access to another flag 'time: (seconds)', which allows a set period in-between each enchantment activation:
description: 'Chance to feed 1 bar of food every few seconds.'
- 'MESSAGE:&aYou have been fed!'
This also allows setting chances for activation as shown in this example:
each time it runs (in this case, every 5 seconds), it has 30/100 chance (30%) to activate and run.
The REPEATING type allows setting **cooldown ** as well, so in case the timer activated it and chance allowed it to run, it will not be ran for the next (in this case 10 seconds).
