what is the point

ward objectives. counter jungle. gank your lanes. do literally anything and you're more useful than someone with an unsated devourer.

it takes 15-20 minutes just to farm enough to get sated. if you're not doing anything to get your team an advantage while the enemy team basically has an afk farmer, that's your fault.

Just like the other jungle items in the game, is an item that has both advantages and disadvantages to using it. One of the most important things to remember though, it is specified primarily for AA-based champions (ones who focus dealing damage with their auto attacks). These types of champions generally have high lock-down potential and are most efficient in 1v1 fights. Trying to combat one of these champions can prove to be very difficult without the proper build/resistances. If you're having trouble against them, my best advice to you would be not to fight them. Rather, retreat and rendezvous with your team to ensure your safety. Even a champion with will be little work against your ally team if alone.

If jungling against an enemy with : This may actually give you an advantage during your early game. While they will spend at least the first 20 minutes of the game farming their jungle for the stacks. During this time, you are free to initiate early ganks, help the laners harass the enemy, possibly counter-jungle them by taking their monsters when farming on one side of their jungle.

Keeping brushes and objectives warded will help reduce the chance of them sneaking up on you to get close and vaporize your health bar. If an area seems iffy, either bring an ally or simply go elsewhere. Risking giving the enemy jungler a kill just so you could steal their gromp or blue isn't worth it. Hope this helps, best of luck!
