Curio is a split optimizer for raid teams running 2-5 splits. It takes your roster and figures out where everyone should go, balancing buffs, roles, and loot priorities automatically.
What is Curio?
Splitting a raid into 2-5 groups is straightforward when it's just about buffs and roles. The hard part is loot. If your top 3 tier priority players all end up in the same split, that's 2 wasted tier tokens. Curio solves that.
You tell Curio who your priority players are for each item. Who should get tier first, second, third, and so on. It then distributes those players across your splits so priorities don't stack up in the same group, while still making sure each split has tanks, healers, raid buffs, and a healthy DPS spread.
How it works
1. Pick your group and set up splits
Open Curio from the sidebar and select your group. Choose how many splits you want (2-5). Your roster loads automatically from Viserio.
2. Configure your roster
On the Configure tab, you'll see all your members and their characters. For each member:
- Their main is always included
- Toggle any alts you want available for splits
- Mark your main tanks so they get distributed properly
- Add helpers (socials or friends) to pad out splits if needed
3. Set loot priorities
This is where Curio gets powerful. Switch to the Items tab and assign item priorities per character.
For example, with 3 splits you get 9 priority slots (3 per split). If you assign your top 3 players for tier as P1, P2, P3, Curio will try to put each of them in a different split. Players P4, P5, P6 go to the remaining splits, and so on. It does the same for regular item drops.
The result: your highest priority players are spread evenly, so each split funnels loot to the right person without waste.
4. Generate splits
Hit Generate Splits in the sidebar. Curio runs through your roster and produces balanced splits in seconds.
Under the hood, Curio uses a proprietary multi-pass optimizer with Monte Carlo simulation to explore thousands of possible splits and converge on the best ones. It balances tanks, healers, raid buffs, spec diversity, loot priorities, and more, all at once.
5. Review and adjust
The Roster tab shows your splits as a spreadsheet. Each column is a split, each row is a member. You can manually swap characters between splits if you want to fine-tune anything.
The Analyze tab gives you a full breakdown of each split: role counts, armor types, specs, raid size, and how well loot priorities are distributed.
Multiple plans
You can save multiple plans per group. Use this to compare different split strategies, like one plan for tier week and another for the weeks after. Duplicate, rename, or delete plans as needed.
Import into Viserio setups
Once your splits look good, head to the Raid Resets page in Viserio. The Curio button next to your setup tabs lets you import a split directly as a new setup. Pick a plan, pick a split, and it creates a new setup with that split's roster, including member containers so alt-switching works per boss.
A note on March on Quel'Danas
Curio works best when you have real item data to prioritize. Since March on Quel'Danas (MoQ) isn't open yet, we'd recommend not setting up loot priorities for MoQ items in Curio right now. The optimizer will factor those items into its decisions, which adds noise when you don't actually know the drops yet. Focus on the first two raids and add MoQ items once it opens.
We'll be doing another polish pass on Curio this afternoon. If you run into issues or have questions, tag Penkek on Discord.
