Kill 30 Enemies with an Elephant
Far Cry 4 TUSKER – Achievement / Trophy Guide
Acquire the Elephant Rider skill for 2 points.
An easy spot to get this is the KYRA TEA WEIGH STATION at X: 345 Y: 378. If you already completed the outpost, you can replay it as often as you like with OUTPOST MASTER.
Once you start the Outpost go left and down to the street. An elephant will always stand there. Ride him into the outpost and take out all enemies including the reinforcement team that is coming. After 3-4 attempts you should get the 30 enemy kills.
