Sion Tips and Tricks
When you’re in zombie mode, keep auto-attacking whatever you can to deal extra damage to towers, the enemy, or even to pick up gold from minions. Set up death bushes around Baron or Dragon to catch enemies wandering through the river. If you cannot use your R to impact your own lane, consider recalling and using it to assist either the mid or bot lane.
