Pets in Grand Blue are not decorations. They fight, they gain experience, they unlock skills, and they physically grow as their level climbs. Leveling one runs on two separate systems, and knowing where the first one stops saves a lot of wasted gold.
Quick answer: Buy Pet Food in Clown Town and feed it to your equipped pet until it hits level 100, then set the pet to Aggressive and let it kill NPCs for every level after that.
Pet leveling in Grand Blue: food to 100, combat after that
Pet Food is universal. One stack works on every pet you own, so there is no separate food type for the chicken, the coyote, or the lion. Feeding raises the pet’s level and its physical size at the same time — a level 1 pet barely reaches your character’s ankle, and a leveled one is hard to miss standing next to you.
The catch is the ceiling. Food stops being useful at level 100. Past that point the only thing that adds experience is the pet actually fighting NPCs, which means the second half of the grind is time spent in combat rather than gold spent at a vendor.
| Stage | Method | What it does |
|---|---|---|
| Level 1–100 | Feed Pet Food bought in Clown Town | Raises level, increases stats, grows the pet’s size |
| Level 100+ | Pet fights NPCs directly | Only remaining source of pet experience |
Where to buy Pet Food in Clown Town
E at the stall to open the purchase window. You will see a Purchase option for the food item and a Bulk Purchase button next to it. Bulk is the one you want — feeding a pet to 100 one item at a time is painful.
Pet behavior settings: Aggressive, Neutral, and Passive
Once a pet is equipped it follows your character around with a health bar, experience bar, level, and current state displayed above it. That state decides whether the pet earns anything past level 100.
| State | Behavior | Use it for |
|---|---|---|
| Aggressive | Attacks any NPC or player outside your party on sight | Leveling past 100 and building skill mastery |
| Neutral | Only fights back after you or the pet takes a hit | Moving through areas without pulling everything |
| Passive | Never fights, even when attacked | Keeping the pet out of combat entirely |
Aggressive is the setting to use while grinding. The pet starts fights on its own, so it keeps collecting experience without you having to open every engagement yourself.
Pet skills and how mastery levels up
Pet skills behave much like your own character’s abilities. New ones unlock at set levels, and some unlocks give you a choice between a couple of buff options rather than handing you a fixed move.
Mastery is separate from level. A skill only climbs when the pet uses that specific skill in combat, repeatedly. Feeding the pet unlocks the skill; it does not train it. That is another reason to leave the pet on Aggressive while you farm — it cycles its own abilities on every mob it engages.
Ability slot cost: what a pet takes from your own kit
Equipping a pet is not free. Pets draw from the same ability slots your own skills use, and the cost scales with how strong the pet is. Manok, the chicken, can cost as little as a single slot. Stronger companions run three slots or more.
Tip: Work out the trade before you commit to a long feeding grind. A pet that eats three slots needs to contribute more damage than the three abilities it just displaced, and a weak pet that still costs a slot is a net loss no matter how much food you pour into it.
How to check pet level, stats, and skills
You will know feeding worked when the level number in that menu goes up and the pet’s model is noticeably larger than it was. Stat values on the Details screen climb alongside the level.
Why a pet stops gaining levels
- The pet is already at level 100. Food does nothing beyond that cap, so further purchases are wasted.
- The pet is set to Passive. It will not fight even when attacked, which means zero combat experience.
- The pet is set to Neutral and nothing has hit you or it yet. Neutral pets wait for the first hit before engaging.
- A skill’s mastery is not moving because the pet has not used that particular skill in combat.
The efficient route is straightforward: bulk-buy food, take whichever pet you plan to keep straight to 100, then flip it to Aggressive and farm NPCs while you handle your own quests. Grand Blue is still in Early Access, so costs, drop rates, and menu layouts can shift between patches — check the current prompt in-game before dropping a large amount of gold at the vendor.
