MACRODIFF PLAYBOOK
How to think about Heimerdinger
Strengths, limits and power windows before you copy a build.
Strength profile
Protection and reset
Peel 3/3 measures how well the classified kit can protect space around an ally after contact begins.
Scaling value
Scaling 3/3 indicates how much the kit classification values longer fights, levels or completed items. It is not a guaranteed late-game win rate.
Control chain
Crowd-control signal 3/3 makes timing with allied setup or follow-up especially valuable. Avoid overlapping the same control window without a reason.
Watch-outs
Do not borrow a frontline job
Frontline is 0/3. If allied durability is low, solve positioning and target access before volunteering to absorb the first contact.
Prefer follow-up to forced entry
Engage is 0/3. When the team lacks a clean opening, let another source create contact and use H-28 G Evolution Turret on the confirmed window.
Execution tax
Heimerdinger is marked complex by the current difficulty band. Missing the primary pattern can change the entire next decision, so practice the reset as well as the hit.
Power windows
Levels 1–2
Establish H-28 G Evolution Turret
The max-order reference is Q → W → E, not necessarily the opening skill order. Check the actual ability learned, range and resource cost before trading.
Early skill points
Check the learned abilities
Do not assume all three basic abilities have been learned. Check the actual skill allocation and each tool's conditions before practicing an entry, follow-up or disengage.
R availability
UPGRADE!!! changes the decision tree
Riot's current description: Heimerdinger invents an upgrade, causing his next spell to have increased effects. Decide whether the cast creates access, protection, damage or an exit before using it.
Completed core
Re-check the team job
After the core build comes online, compare engage 0/3, peel 3/3, scaling 3/3 and frontline 0/3 again. Items can change priority without changing champion identity.
ROLE PLAN
Lane and tempo checklist
Trade around the wave
Use H-28 G Evolution Turret as the first repeatable pattern, but keep enough space to disengage after the trade. Riot's current description: Heimerdinger lays down a rapid-fire cannon turret equipped with a secondary pass-through beam attack (turrets deal half damage to towers).
Track the long lane
Before pushing past river, account for enemy jungle access and your own escape tools. A favorable trade is not automatically a safe wave state.
Choose side lane or grouping
With frontline 0/3 and engage 0/3, decide whether Heimerdinger should absorb side pressure or arrive first to the next objective. When UPGRADE!!! is available, read its actual purpose before committing; not every R is an engage or escape.
5V5 PLAN
Team-fight responsibilities
Let contact become visible
Engage 0/3 favors a follow-up posture. Keep H-28 G Evolution Turret available until the first threat and target are clear.
Protect the second line
Peel 3/3 makes the space around the carry a valid win condition. Do not spend every control tool on the first visible tank.
Re-evaluate after the first cooldowns
The first exchange changes health, spacing and available tools. Pause long enough to choose between continuing, peeling back or changing target; do not replay the opening automatically.
