In this video guide I will show you a few ways to send 25 enemies over the edge. The first way this can be done it with the ability called
Evasive Kick. This ability can be found under the Lightsaber skill tree. The second more effective way is to wait until you get
Force Push. The ability is story related so you will know when you get it. If you want to make this even easier you can get the ability called
Mass Push under the Force skill tree to spend them flying further.
There are some ledges on
Dathomir to be able to either kick them off or force push them off. The area I farmed it at was on the planet
Zeffo in the Ice Caves area. This was right after I got my Force Push ability, but before I tried to leave the planet.
There is a spot right next to one of the lifts and meditation spots to farm. In that area there are three rats on a ledge below next to the meditation spot. You will notice the holes in the ground for the right area. Once you jump down next to the holes they will pop out. Just line them up with the ledge and push them off. If you have to wait for your force ability to recharge, you can still knock them off with the basic refill you get from the waiting. Once you knock them all off, go to the meditation spot and rest to re spawn the rats. Then simply keep doing this method until the achievement pops.
