Tips for Newbies ◕⩊◕

  1. Save your dice between events to aim for higher points goals.
  2. Multipliers are unlocked as you collect more dice. They let you get more rewards from a single roll BUT it will cost you just as many dice (20 dice = 2x, 30 dice = 3x, 50 dice = 5x, 100 dice = 10x).
  3. Save gems for this event (unless there is a clearly better event announced). This is one of the best events to be spending your dice (Island Pack 3, Mythstone Chests, etc.)
  4. Once you are past 150k power, we strongly recommend saving resources to maximize number of dice you get from each rotation (Chroma Keys, Wishes, Shovels).
  5. Read the FAQs.
  6. Check out the rest of the guide as hopefully they make more sense now.
  7. Ask questions on Archero 2 Discord.

Multiplier Map ( • ̀ω•́ )✧

How do I use this map?

  1. Check the map for the tile you are on
  2. Change your multiplier to match the tile on the map (go as high as you can if you cannot do 10x)
  3. Roll
  4. Repeat

What is the benefit of this map?

This map is not the most efficient one to get to 100k (it requires 0.25 dice more), but in return, you get on average 0.4 extra chromatic keys and 280 gems. For us, that small tradeoff is totally worth it.

Now you might be thinking—are there maps that use more dice but give even bigger rewards? Yep, there are. But we still think this one's the best overall. Dice are super important since they are the only way to get treasure coins and grab those exclusive Island Store loot. We do not want people using a bunch of extra dice in one go and then not having enough saved up for the next run.

How did we come up with this map?

  1. Calculated the expected value of each tile based on its points value and probability of getting dice.
  2. Compute the projected value of each tile by factoring in the expected value of reachable tiles.
  3. Toggled tiles—starting with those with the highest projected value—to 10x in order to maximize overall PPID.
  4. Ran 10k simulated event runs on the finalized map to validate our approach.

Did we try other maps?

  1. We ran simulations on several other proposed maps, but ours outperformed them.
  2. We also explored "safer" maps with lower variance, but none offered a worthwhile tradeoff in efficiency.

Should I roll? ¯\\_(ツ)_/¯

Decide for yourself when you should start rolling based on your own risk tolerance.
You can save dice between events to have a better chance of hitting your points goal.
The table below shows you the chance of reaching that points goal based on how many dice you started with.
Tip: During key rotation, you should at least roll until you get 50+ points. This will assign you the lowest rank of 1001+ which still gives one free Chroma Key.

*Start Dice is the amount of dice you have BEFORE you do any rolling. Go to the 'Where are the dice?!' section to see which quests impact this.

If you already started to roll and you want to check what are your chances of reaching your goal, you can use this tool to do so:

Points per Dice Calculator ◁ |⚙⌨⚙| ▷

Use this to calculate your PPID to see how your run compares to others.

How many points did you get this run?

How many rolls did you do in total?

Did you keep track of the number of extra dice you got from the board?

FAQs (º~º)

What is Points per Dice (PPID)?

PPID is calculated as:
= Total Points / Number of Dice BEFORE Any Rolling
= Total Points / (Start Dice - End Dice)

This means it EXCLUDES dice gained from:

  1. Roll Dice Tasks
  2. Points Breakpoints
  3. Collecting dice from tiles on the board

Why is this important?
PPID better captures the benefit of collecting extra dice while rolling—something that Points per Roll (PPR) does not fully reflect.
PPR = Total Points / Total Rolls Done.

Take this example:
We all agree that landing on a 2x dice tile is a win!
PPR sees it as a negative, since you are ending up with more rolls, which dilutes the score.
PPID, on the other hand, treats it as a positive—more like a refund. You used a dice but got two back.

Should I buy the Island Pack 3 for 750 gem?

Based on our estimates, this pack is worth at least 1100 gems.

Math:

Average for 100k points:

  1. Number of Dice Needed: 269
  2. Points Rewards: 55k gems (40k from loot + 10k from mythic artifact + 5k from treasure coin)
  3. Gems Gotten: 2771.18 gems
  4. Chroma Keys Gotten: 4.16 keys

Value of a single dice: (55k gems + 2771.18 gems + 4.16 keys * 400 gems) / 269 dice = 220 gems

Why aim for 100k points? Should we roll more if we have more dice?

Hitting 100k points strikes the best balance between breakpoint rewards AND ranking rewards. It also rounds you out to 10 artifact shards, the amount needed to actually unlock it.

  1. Going straight for 100k (while skipping events) instead of aiming for 20k every time gives you ~3 more treasure coins, plus extra treasure coins from better rankings.
  2. Hitting 100k twice instead of 200k once earns you ~10 more artifact shards, at the cost of only ~2 treasure coins.

Now whether it is worth spending extra dice to go past 100k is totally up to you—but here are a few things to think about:

  1. Will you still have enough dice to roll comfortably next time you want to play?
  2. Can you hit the next 10k milestone? This guarantees you another treasure coin and 10 chromatic keys.
  3. Any little gains such as aiming for the next reward tier will have to be based on your gut feel. Good luck!
Is there a particular rotation that is better?

Each event rotation focuses on a single resource for the week. You can use that resource to get more dice AND you can roll dice to earn more of that resource. Each rotation also includes a matching artifact as a reward.
The event rotations are:

  1. Chroma Keys and Goldfinger Artifact
  2. Wishes and Golden Fleece Artifact
  3. Shovels and Golden Mask Artifact

We recommend prioritizing getting all three artifacts first to complete the set bonus. Once that is done, shift focus to only the Chroma Key rotation as they are the best resource and Goldfinger is the best artifact.

What should I buy in the exchange shop?
  1. Cupid's Bow: Cheap, cost only 2 tickets.
  2. Cupid's Arrow: Completes the set and works across all modes. Worth considering getting stars as a Dragoon Helmet user.
  3. Thronebreaker Shield (PVP only): Cheap, cost only 2 tickets.
  4. Demon Artifacts (PVP only): Good effects.
  5. Otta: 2-star is when he starts to shine in PVP and possibly Boss Battles. Only available in this shop and unfortunately requires a longgg-term commitment (200 shards).
  6. Battle Rite Artifacts (PVP only): Worse effect than Demons and has a meh set bonus.
  7. Epic Characters: A good way to get it although pricey (only Seraph and Dracoola though).
  8. Rare Characters: Just don't.
  9. If no good options, you should save as they are adding more loot to the store

I want to track my run. Is there a tool I can use to do so?

Yes! Here is a Google sheet you can make a copy of and start tracking your run.
Dice Event Tracker
If you want to help out, DM your run to @fierywind on Discord as we are doing a study on people's runs.
If you have any questions, feel free to reach out to @kaithulhu_ on Discord.

I think I came up with a better multiplier map. Is there an easy way for me to test it out?

Yes! You can run the same Python script to simulate the event, where you can test out your new map:
