Mordelium is a Tier 3 flying herbivore in Creatures of Sonaria, and it only appears during the Summer Paradise Event. It is built around poison. It cannot be poisoned itself, it poisons anything that hits it, and it can bounce incoming damage back at attackers. First added in 2022, it returned as part of the Summer Paradise Event 2026.
Quick answer: Buy Mordelium from the Summer Paradise Shop for 6,000 Pearls while the event is live. Earn Pearls by finishing the daily event missions (up to 425 every 24 hours) and by delivering matching colored pearls to oysters.

How to get Mordelium in Creatures of Sonaria
Mordelium is event-locked. You can only obtain it while the Summer Paradise Event is running, and it is purchased with Pearls from the event shop. Once the event closes, the creature leaves the shop until a future Summer Paradise Event brings it back.


Note: A trial version is also sold in the Trial Creatures Shop for 150 Shooms (male) or 1,500 Shooms (female) if you want to test the creature without spending Pearls.
There is no officially confirmed end date for the current Summer Paradise Event. Past events have typically run for about four weeks, so plan your Pearl farming with that rough window in mind rather than assuming a fixed deadline.

Mordelium is a Paradise Special classed as a Tier 3 (Medium) flier with a herbivore diet. It reaches full growth in 25 minutes and weighs 2,400 pounds. Its ground sprint is unusually fast for a flier, while its flight speed sits at a solid mid-range value.

Passive abilities
Mordelium leans heavily on defense and pack support. Its passives are always active once the relevant conditions are met, and several of them scale better when the creature is near allies of the same species.
| Passive | Effect |
|---|---|
| Block Poison (1.00) | 100% poison resistance once the creature reaches max age (100). At full growth it cannot be poisoned, and any poison applied is healed instantly. |
| Broodwatcher | Speeds up nearby egg hatching by applying a Gestation stack (+2.5% per stack, up to 5% total). Sitting near a nest also grants defensive value. |
| Defensive Poison (2) | Applies Poison status to any creature that attacks it in melee. The effect stacks with itself the more you are hit. |
| Diver (4) | Lets the flier keep flying and diving underwater for a short window (about 4 seconds) while holding its diving speed. |
| Strength in Numbers | Grants a 7% stamina regeneration boost and 1.5% damage boost, scaling with how many same-species allies with the ability are nearby. It gives nothing when Mordelium is alone. |
Active abilities
Mordelium has two active abilities you trigger yourself. Reflect is available throughout its life, while Yolk Bomb only unlocks once the creature reaches the adult stage.
| Active ability | Effect | Cooldown |
|---|---|---|
| Reflect | Grants 2 stacks of Reflect status, bouncing physical damage back onto attackers for a short time. | 45 seconds |
| Yolk Bomb (Fortify) | While flying or gliding, drops an egg straight below that explodes on impact with a 40-stud radius. Caught creatures take knockback, 2 stacks of Slowed, and 4 of the type-specific status effect. | 30 seconds |
Note: Yolk Bomb applies a Fortify effect rather than a purely offensive payload, so it can also support allies. It does not remove any harmful status they already have.

Growth stages
Mordelium takes 25 minutes to reach full grown from hatching. If you keep aging it, it continues through elder and veneration stages, which take considerably longer.
| Stage | Time |
|---|---|
| Teen | 8 min 20s |
| Adult | 16 min 40s |
| Full Grown | 25 min |
| Full Elder | 50 min |
| Full Sage | 12h 50min |
| Full Venerated/Ancient | 24h 50min |
Between its full poison immunity, damage reflection, and fast ground sprint, Mordelium works best as a durable support flier that punishes attackers rather than out-damaging them. As long as the Summer Paradise Event is running, banking 6,000 Pearls through daily missions and oyster deliveries is all it takes to add it to your collection.
