1. Pick Lavamancer on any map (Some spawns are harder than others, try gates at dragonfall left or right lane)
2. Jump and then use the right click ability (charge, dash) and aim for the center of the portal and the center of the lane behind it

3. If you do it wrong, the Lavamancer will be stuck in mid air while still flying and right clicking will reset him to before the portal
4. If you do it correct, you land there naturally behind the spawn portal and on some maps you can build things there.

Some Lanes are harder to get, because you have to aim at the right place, or just charge very shortly

This bug only works when jumping, a ground dash will not get you through the spawners
Expected Results: You shouln't get behind the spawners
Thank you for your report, we will look at this issue.
