Solve your splits before you step into raid.
Curio takes your roster, your loot priorities, and all the constraints that make splitting hard, then figures out where everyone should go. 2 splits or 5.
Splitting raids is hard. It shouldn't be.
If you've run splits, you know the drill. You open a spreadsheet, start sorting 40+ characters, and immediately hit the same problems: three people who all need the same trinket are in the same group, one split has no Bloodlust, and the tier tokens are stacked 8 to 2.
Every constraint you fix breaks something else. You move someone for token balance and now their split is missing a battle res. This takes hours, and you do it every week.
Curio holds all of these constraints in its head at once. Tier tokens, buff coverage, role counts, main/alt priority, per-item loot priority. It finds a valid arrangement and scores it, so you can compare options instead of guessing.
How it works
Configure Your Roster
Import from Viserio or set up directly. Tag each character as main or alt, mark who brings which buffs, set your tanks.
Set Loot Priorities
The item priority matrix shows every boss drop against every character. Viserio wishlists and droptimizer DPS gains plug in directly.
Optimize & Go
Run the solver, review the scored splits it produces, test them against simulated loot. On raid night, keep Curio open as your loot screen.
Pre-plan your split week
The best time to find out your splits have a problem is before raid, not during. Configure your splits ahead of time, then run simulated loot drops against them. You'll see exactly where characters are competing for the same item in the same split, where tier tokens are stacking, or where a buff is missing.
Top guilds do this every week. For teams splitting for the first time, it skips the painful trial-and-error phase entirely.
Who is Curio for?
What the solver actually considers
Tier Token Distribution
Distributes plate, mail, leather, and cloth token types evenly so one split isn't stacked with the same group.
Buff Coverage
Checks that each split has Bloodlust, battle res, raid buffs, and relevant debuffs covered.
Role Balance
Distributes tanks, healers, and DPS evenly. Avoids putting duplicate healer specs in the same group.
Main vs. Alt Priority
Distributes mains fairly. Places alts and lootbodies where they complement the split rather than crowd it.
Loot Priority
If two characters both need the same trinket, they go in different splits. Uses the item priority matrix to minimize competition.
Spec Diversity
Spreads specs across groups so each split has varied damage profiles and doesn't stack the same armor types.
The full toolkit
Item Priority Matrix
A spreadsheet of every boss drop against every character. Set per-item priority levels, and pull in Viserio wishlist and droptimizer data to fill it automatically.
Simulated Loot Testing
Run fake boss kills against your splits to see how loot would actually distribute. Catches problems that look fine on paper but fall apart when items drop.
Live Raid Mode
Keep Curio open on a second monitor during raid. When loot drops, it shows you who needs what and tracks what's been handed out.
Viserio Integration
Your Viserio group, roster, wishlists, and droptimizer DPS gains carry over. If you already use Viserio Cooldowns, setup is just picking your group.
Part of the Viserio ecosystem
Curio and Viserio Cooldowns share the same groups and rosters. Wishlist priorities and droptimizer DPS gains from Viserio feed directly into Curio's item priority matrix, so your cooldown planning and loot planning live in the same place.
