Build a safe health-and-wave lead

From lane start through the first reset and early objective cycle; adapt the default to wave state and jungle information

Early, prioritize experience, farm, and a wave state that permits a reset without donating control. Use Q to last-hit or chip when the enemy must approach, and avoid extended trades inside a larger enemy wave; E's missing-health damage is a threat after the trade is controlled, not a reason to start one. If you can push safely, crash before recalling; if not, accept lost CS rather than losing health and the bounce. Your transition is a stable wave and a useful reset, not a forced solo kill. When ahead, hold the enemy near your side only while you can collect the wave; when behind, farm under tower and wait for the wave to return.

Lane

Trade health for the wave, not for a health-bar contest

If the first three waves let you reach the enemy side without surrendering a large health lead, use Q when the opponent must approach a last hit, then use the threat of E's missing-health damage to make the crash possible. If the enemy wave is larger or your Q is unavailable, take safe experience and Q farm instead of forcing a melee trade. After the wave crashes, recall or move only while the next wave no longer requires your presence; otherwise the lost reset turns your pressure into a frozen lane against you.

With Dr. Mundo

• If Mundo is applying side-lane pressure, let him crash a wave before forcing a mid fight; the enemy must choose between answering him and contesting you. If Teleport is available, hold objective pressure until his side-lane threat can create an answer, but do not demand a blind flank from a champion whose value is walking through space.
• If Mundo walks forward with R active and Q available, follow closely enough to use the target he slows or the frontline he occupies. His durability creates time, not guaranteed damage; allies who arrive late turn his first contact into an isolated death and waste the regeneration window.
• If Mundo's passive cannister drops during an engage and the area is safe, protect his route to it with threat or body position. If it lands inside enemy control, do not make a rescue play that loses the fight; keep attacking the nearest safe target while Mundo exits or re-enters without it.
• If Mundo is behind, give him the safe side wave and let him approach fights as a peel body rather than demanding a carry assassination. Group around his Q slow and sustained presence, then convert an enemy overextension into a tower or objective instead of chasing past the next wave.
