Echo Slam has initial damage plus echoes created by enemies hit. A sparse target setup can produce much less damage than a dense group; real heroes create two echoes in the current description.

The ultimate’s reputation comes from interactions among nearby units, not a promise that every single-target cast has the same burst. Count the sources around the intended target before using a crowded-fight expectation.

What to do, in order

  1. Inspect enemy density around the fight, including units besides the hero you most want to kill.
  2. Separate the initial hit from the echo damage in your mental model. The tooltip contains both.
  3. Check whether the intended units are inside the relevant area when the spell resolves, rather than counting enemies visible elsewhere on the screen.
  4. After a low-damage cast, compare the actual unit arrangement with the arrangement you expected.
  5. Only then inspect modifiers or your follow-up combo; do not immediately assume the ability’s base damage was missing.

Match the symptom to the cause

It was huge against a crowd but weak against one hero

The number of echo sources changes. Those are not equivalent setups for a damage comparison.

I multiplied one listed number by every unit on the screen

Visibility on screen is not inclusion in the ability’s area, and echoes need nearby recipients. Avoid an unverified whole-screen total.

I treated heroes and ordinary units identically

The current description explicitly says real heroes cause two echoes. Do not replace that with an outdated one-echo assumption.

Apply it to one concrete situation

A hero isolated from other enemies is a different target setup from a hero standing amid a dense enemy group. The useful pre-cast question is how many eligible echo sources and nearby recipients exist—not just whether the ultimate icon is ready.

Current base tooltip values

Values below are the unmodified fields in Valve’s dated English ability data. Slash-separated entries are listed level values, not a recommended skill build. Read the field label: damage, range, duration and percentages have different meanings. Upgrades and modifiers can change your client’s values.

Tooltip fieldListed base value(s)
Mana cost150 / 200 / 250
Cooldown (seconds)130 / 120 / 110
RADIUS700
ECHO DAMAGE70 / 90 / 110
INITIAL DAMAGE100 / 140 / 180

Limits that matter

The dated data lists a 700 base radius, but this page does not publish a simplified guaranteed total-damage formula. Echo geometry, unit categories and defensive states make an unsupported multiplication misleading.

Related questions

What are the base initial-damage values?

The current list is 100/140/180 by level, with echo damage listed separately as 70/90/110.

Does initial damage include every echo already?

No. Treating the initial value and echoes as the same field obscures why different unit arrangements produce different results.
