Echoes of Mystralia spell builds — Memories, elements and runes

Memories, not runes — get the naming right first

If you searched for “Echoes of Mystralia rune builds,” here is the correction that matters: this game does not craft spells from runes. Runes were the system in Borealys Games’ earlier title, Mages of Mystralia (2017). In Echoes of Mystralia the official crafting components are called Memories — the official site describes them as “pure magic” that you combine, reorder, modify and enhance. Everything below uses the official terminology.

This page covers only what official sources describe. The game launches into Steam Early Access on August 11, 2026, so no build has been tested against release balance yet — see the beginner guide for the launch timeline.

How the spellcrafting canvas works (confirmed)

From the Steam page and official website:

1. You collect Memories during and between runs.
2. Spells are assembled on a freeform spellcrafting canvas.
3. Combining and reordering Memories changes how the spell behaves — placement matters, not just which components you own. The Steam page’s line is “If you can imagine it, you can craft it.”
4. Official examples of results include thunderbursts, freezing tornadoes and fire vortices.

Press coverage of the Early Access announcement describes millions of possible combinations and lists 12 spell forms to experiment with at launch. The Steam page itself lists 16 starting spells and 7 unique magical elements; it does not name the individual elements or forms, so we do not list names we cannot source.

Demo content vs Early Access launch content

The free demo (on Steam since February 16, 2026) is a subset of the launch systems. Numbers below come from the two Steam store pages:

If you want to practise the canvas before launch, the demo is the only verified way to do it right now.

What shapes a build beyond the canvas

Officially confirmed build-adjacent systems at Early Access launch:

• Relics (40+): the demo page describes Relics as pushing “your builds to their full potential.” No individual Relic effects are published yet.
• Altar upgrades (50+): listed on the Steam page as launch content; details unpublished.
• The Lotus: the permanent progression system carried between runs.
• Azimuth Temple: the hub where Watchers develop skills between expeditions.

How these systems interact numerically is not documented anywhere official. Guardians and Elite fights are the encounters your build ultimately has to answer — see the bosses page for what is confirmed about them.

Why there is no tier list here yet

A responsible build guide needs numbers: Memory effects, element interactions, cooldowns, scaling. None of that has been published by Borealys Games, and the game is a roguelite whose events and encounters renew each run, so pre-release “best build” lists cannot be verified. Specific Memory combinations, element rankings and damage figures are not yet verified, and we will only add them from firsthand testing after the August 11 launch. If another site shows you a launch-week tier list sourced from nothing, treat it as speculation.
