Auto Spawner - Safari net has durability before destorying the contained mob

[Razorskills]

Basically I am trying to find a way to make the autospawner a bit harder to receive all the ender pearls you need or blaze rods in the first day you have it running.

I still want it to be possible for people to use the auto spawner, just a bit harder. I was hopping there might be a way for the autospawner to break the safari net after a certain amount spawned or maybe a chance for it to break. And when it breaks the player needs to go out looking for another enderman. Instead of sitting afk on the server collecting ender pearls or whatever mob drop they want. I know I can make it more expensive to spawn them, but people can just set up a bigger power system and still just sit there.

I wonder if you did implement the chance to break, if it would be also possible to make mobs spawned in the autospawner not able to be used in autospawner due to it being a clone. Maybe some kind of tag set to the mobs spawned in the autospawner that when you mouse over the safari net, it will say "cloned" or "copy of" something like that, and a config that could disable the use of clones in a autospawner.

(for those that like more of a challenge..)

Also if the safari net breaks, I was thinking it could either just disappear and the player would wonder who stole it, or maybe it could actually become a new item 'broken safari net' then the payer would know what happened, and could maybe use the old net to craft a new one. Instead of collecting another ghast tear, it could be used in its place or however you think it would make sense.

This is just an idea, If you like it, then its all yours :D
