The Soul Urn is a strategic map objective that you should prioritize alongside your team. Follow these tips and tricks to make sure you'll succeed:
Pushing Side Lanes
As the Soul Urn spawns at a fixed time, it is important that you push the wave right before it spawns. This will allow you to pick up the Soul Urn while the enemy team is busy taking down your creeps.
Enemies must choose between farming the creep wave and defending the Guardian, or picking up the Soul Urn, which puts you in an advantageous position right away.
Get Help from Teammates
Once you pick up the Urn, the enemy team will try to intercept you in the Jungle before you can deliver it. It is likely that you will encounter players from the lane where you must deliver the Urn, and players in the Middle (Blue) lane might rotate to catch you as well. Communicate with your team so they protect you while you deliver the Soul Urn.
Use the Soul Urn as Bait for a Fight
You can use the Urn to lure enemy players to your position and force them into a fight. This is especially useful when your team rotates to help, which will put your team at a numerical advantage.
Don't Leave your Lane Unattended
You must leave your lane to deliver the Soul Urn, which will put your lane teammate at a numerical disadvantage against the two enemy laners. If your ally hero does not have the ability to push the wave or defend the Guardian, they might get killed, and your team might lose a structure, which is more important than the Soul Urn.
For these reasons, it is important that you know beforehand that your ally can withstand your lane in your absence. Pushing the lane before delivering the Urn is a good way to keep pressure off your lane.
