Core Keeper build planner
Pick your gear and its upgrade level, set your skills, and see every stat your build adds up to. Changes save in your browser.
Equipment
Your builds
Keep a build for each playstyle. Share a link, or copy the build as text to back it up.
Skills & talent calculator
Set each skill's level to see how many talent points you have, then spend them. Each talent takes up to 5 points, and 5 points in a talent opens the next tier.
Core Keeper equipment database
All armor pieces, accessories, weapons and tools, with stats at any upgrade level. Sort by the stat you care about.
Core Keeper set bonuses
Every armor and accessory set, the pieces it needs and what it gives. Equip a whole set to your build in one tap.
How Coreplan works
Quick start
- Build: tap a slot to pick an item, then choose its upgrade level. Rings have two slots.
- Skills & talents: set your skill levels and spend talent points.
- Read the totals: the summary adds up everything, shows set bonuses (and how close you are to the next one), and estimates your weapon's damage.
- Save and share: keep several builds, copy a share link, or download a build to back it up.
Where the numbers come from
Item stats at every level, set bonuses, skills and talents come from the game data modules published on the Core Keeper Wiki. The item data is labelled game version 1.2.0.7, so a few values may have changed in later updates. If you spot one that doesn't match your game, please report it.
What's an estimate
The weapon damage and DPS figures are estimates and have not been verified in-game. They assume:
- damage bonuses that match the weapon (for example physical melee damage and "damage") add together, then multiply the weapon's base damage;
- attack speed bonuses shorten the weapon's cooldown (magic weapons are not sped up);
- a ±10% damage spread, as the game shows on tooltips.
They ignore crits, enemy armor, conditional effects ("after dodging", "at max health"), food, pets and your base stats.
Talent tiers
Each skill gives 1 talent point every 5 levels plus 5 at level 100 (25 total). Talents hold up to 5 points. Coreplan opens a tier once any talent in the tier below has 5 points. In-game the tree branches, so a specific talent may need a specific parent. Check the game if a path looks off.
FAQ
How many talent points does a skill give?
One every 5 levels, and 5 more at level 100, so 25 per maxed skill. That's not enough to max all 8 talents in a tree, so plan which ones you want.
Do two copies of the same ring count towards a set?
No. Sets count different pieces, so a duplicate ring only counts once. Coreplan counts sets the same way.
Does upgrading gear raise its stats?
Yes. Upgradable gear gains stats each level up to level 20. Use the level picker on each slot, or "All gear to max level".
Is reinforcement included?
Not yet. Reinforced gear's extra stats aren't in the data this tool uses.
Why aren't pets and food included?
They're on the list for a later update. For now the totals only cover gear, sets, skills and talents.
