1. Buy the item "Destroyers Stone". You can use the active ability to "snipe" objectives. (You also need it to sustain in the "Jungle")
2. Pick a "Tank" or "Warrior" hero in "Jungle". The longer you survive a teamfight the more likely it is to secure the objective.

3. Kill the enemie teams "Jungler". Every time the enemie teams jungler dies it is a good oppertunity to start an objective.
4. If your team is not able to kill the enemie "Jungler" you should block him from reaching the objective or stun him in the right moment so he is not able to use "Destroyers Stone" active ability.
5. If you cant kill or block the enemie "Jungler" you can still try to steal the objective. For this you need an ability which can stun the enemie hero. (eg: Crunch, Rampage or Steel...). Right before the objective reaches critical health you should use your stun on the enemie "Jungler" and use your active "Destroyers Stone" ability. The stun won't let the enemie "Jungler" use his snipe while you can steal the objective.

5. When objectives are up you should always have the "Destroyers Stone" active available. Don't use it on jungle minions.
6. You can evolve "Destroyers Stone", which enables the active to be used on enemie heroes. This can be helpfull to secure a kill bcs it will slow the enemie and prevents "travel mode".
