MACRODIFF PLAYBOOK

How to think about Cassiopeia

Strengths, limits and power windows before you copy a build.

Strength profile

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.

AP damage identity

MacroDiff classifies the current profile as AP. Use that fact when checking team damage balance; it does not replace item- or ability-level scaling details.

Control chain

Crowd-control signal 1/3 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.

Limited protection after commitment

Peel is 0/3. Spending the key control or mobility tool aggressively can leave no answer for the return engage.

Prefer follow-up to forced entry

Engage is 0/3. When the team lacks a clean opening, let another source create contact and use Twin Fang on the confirmed window.

Power windows

Levels 1–2

Establish Twin Fang

The max-order reference is E → Q → W, 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

Petrifying Gaze changes the decision tree

Riot's current description: Cassiopeia releases a swirl of magical energy from her eyes, stunning any enemies in front of her that are facing her and slowing any others with their back turned. 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 0/3, scaling 3/3 and frontline 0/3 again. Items can change priority without changing champion identity.

ROLE PLAN

Lane and tempo checklist

Tie spells to wave control

Twin Fang is the first-max pattern in the current build snapshot. Use it with a clear purpose: pressure the opponent, secure the wave, or preserve priority—not all three at once. Riot's description: Cassiopeia lets loose an attack that deals increased damage to Poisoned targets and heals her for a percentage of the damage dealt. If the target dies from this attack, Cassiopeia…

Move on a finished wave

Roam or place deep vision after the wave is handled. Leaving a bad wave can turn a successful move into lost experience and a weaker return timing.

Hold the central angle

Your mid-lane job changes with engage 0/3 and peel 0/3. Start only when the kit supports it; otherwise keep the route between your carry and the threat. When Petrifying Gaze 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 Twin Fang available until the first threat and target are clear.

Preserve an exit

Peel 0/3 means the kit may not rescue a bad entry. Keep movement, range or terrain between Cassiopeia and the return threat.

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.
