Iron Soul Dungeon Pets: All 6 and Their Evolution Chains
Every pet in Iron Soul: Dungeon follows the same three-stage chain — Starter, Phase 1, Phase 2 — and the equipped pet is one of the four slots that can carry sub-stats, alongside your weapon, armour and scroll. That makes the pet a stat slot as much as a companion.
| Pet | Stages |
|---|---|
| Icy Dragonet | Starter → Phase 1 → Phase 2 |
| Storm Eagle | Starter → Phase 1 → Phase 2 |
| Divine Dragonet | Starter → Phase 1 → Phase 2 |
| Moon Spirit | Starter → Phase 1 → Phase 2 |
| Phoenix Kitsune | Starter → Phase 1 → Phase 2 |
| Faith Guardian | Starter → Phase 1 → Phase 2 |
Getting and ascending a pet
Pets hatch from eggs, and ascension moves a pet from one phase to the next. The official wiki's pet table records the chain for all six but leaves the per-stage ATK and HP values, the exact level requirement for the first evolution, and the Phase 1 to Phase 2 condition marked as unknown — the entries literally read "Reach Lv." with no number, and "???" for the second step.
So this page states the chains and stops there. Any site quoting exact pet stats or a specific ascension level right now is quoting something no published source contains. When the wiki fills those fields in, they will appear here with the check date.
Pet affinity and expeditions
Two related systems come up constantly in searches — pet affinity and pet expeditions — and neither has a documented page on the official wiki yet. Both are in the game; neither has published values. They are on this site's open-questions list rather than written up from guesswork.
