Create a lane zone before a fight
From spawn through the first meaningful crash and the first objective setup; use wave state and available Tentacles as the transition condition
From the first wave until the first meaningful crash, identify which side of the lane gives you useful impassable terrain, then farm toward that side without spending mana on pointless trades. If the enemy walks up while a key cooldown is unavailable or into a Tentacle’s reach, Test of Spirit can create a short all-in window; follow with Harsh Lesson only when nearby Tentacles can swing. If you are pushed out or behind, prioritize safe CS and XP, avoid fighting in a full enemy wave, and crash before recalling when the wave allows. Transition after a meaningful crash so you can reset or move for the next map event rather than forcing a fight.
