Resonance

Resonance is the per-creature growth system in Aniimo, the way you push an individual Aniimo's power beyond its base level. Officially called Resonance Training, it is one of the four pillars of raising an Aniimo (Egg Hatching, Resonance Training, Evolution, and Twining), and it is the real progression ladder rather than a fixed hidden-stat or IV-style slider. Each Aniimo unlocks successive Resonance tiers as its level climbs, with the official wiki documenting tier breaks at Lv 20, 30, 40, 50, 54, and 60. Every tier is paid for with graded training materials called Astranite, split into three grades. Basic Astranite feeds the early tiers (the Lv 20 and Lv 30 breaks), Standard Astranite covers the mid tiers (Lv 40 and Lv 50), and Advanced Astranite is reserved for the top tiers (Lv 54 and Lv 60). Higher tiers cost more units, so each grade is consumed in small batches as you advance. Because Resonance is applied to one creature at a time, it matters most when you are committing to a specific Aniimo for your team: you funnel the matching Astranite grade into it to graduate it through each tier and unlock its full stat ceiling. Plan your Astranite stock around which Aniimo you intend to invest in first.
