3rd Anniversary Event Currencies: Where to Get and How to Spend (Parts 1 & 2)

This guide was written by u/JConqistador and originally published on Reddit’s Idle Heroes sub.

Part 1. Intro and Event Currency Overview

There is only ONE currency which is available for this event: Koi. DO NOT blow all of your Koi at the end of the week thinking they’ll expire. This event is WILL continue into next week with Prophet Orbs, so take that into consideration when planning your spending.

As of right now, there are 3 ways to get Koi.

  • Randomly dropped from collecting campaign loot (if this is like prior event drops, it will be around 200-300/day)

  • Daily rewards (80/day free, up to 200/day by spending gems)

  • Rewards for hitting tiers of event completion (1600 per full completion using 650 scrolls)

Total for the week you can expect about 3700 Koi from campaign drops and daily rewards assuming you buy both gem boxes. If you can spend 2600 Heroic Scrolls you can get up to 10,000 Koi without spending any money, but chances are most F2P or low VIP players will end up with 4000-7000 Koi for the week.

Next week these will all be replaced with similar rewards for completing the Prophet Orb event.

For further details about estimating the amount of Koi you can get over the next two weeks, see the following threads:

Sachet (gem boxes) and Event Packages

The Sachets are this event’s replacement for the standard Gem Box.

There are two Sachets and each one costs 4888 gems and will give you 100 Koi, 4 Heroic Scrolls, and 1 Prophet Orb per day for seven days for a total of 700 Koi, 28 Heroic Scrolls and 7 Prophet Orbs.

Even ignoring the Koi, the value of the Heroic Scrolls (3500 gems) and Prophet Orbs (3150 gems) alone is worth spending the gems when compared to the best Aspen rates so you should definitely buy them if you can.

There are two different types of Event Package for P2P Players. One geared towards light spenders, and one geared towards whales.

The single 3rd Anniversary specific package is for light/value spenders.

  • $20 Package (3rd Anniversary Card): 12000 gems, 30 feathers, Variable Gold (1.32m gold/level)

    Feathers don’t have a set value, but a reasonable estimation seems to be 100-150 gems per feather. That would put the total value at 15000-16500 gems or 750-825 gems/dollar. This is about on par with the Monthly Senior Privilege Card (800 gems/dollar) and much better than the Monthly Privilege Card (560 gems/dollar). This package doesn’t give any event currency so there is no need to buy this unless you want the gems/feathers at a decent price.

The standard “Value” packages are for people with lots of money to burn. You shouldn’t buy these unless you need the Event Currency to hit a premium reward because the gem/dollar ratio is terrible. Each of these packages can be bought up to 5 times.

Spending Koi

You should probably wait till the end of the event to make any Koi purchases. These rewards aren’t going anywhere for two weeks. Use that time to learn more about the power level of the new heroes and see how many Koi you will be able to get in Week 2. You will be able to make a more informed decision about what to purchase if you wait. You may need to make an exception if you need the scrolls or orbs you can buy here to hit an event threshold.

The top reward(s) for this event are premium artifacts, but it is highly unlikely you’ll be able to reach that level without spending a decent chunk of change. There are 5 tiers of rewards, each with 2-3 items that you could purchase. In order to unlock a higher tier, at least one item must be purchased from the tier below. You’ll also get a bonus reward for each purchase on each tier.

TierItem 1(cost)Item 2(cost)Item 3(cost)Bonus for each PurchaseMinimum cost to unlockRecommendation & Notes
1Sleepless Skin(600)10 Heroic Scrolls(600)5 Prophet Orbs(600)2 Super Wishing Coins0From a pure value perspective, the Orbs are the best. If you need some emergency scrolls to hit a event reward threshold for some reason (like the fact that the event needs hundreds more scrolls than you were expecting), the scrolls aren’t a bad option, but worth about 1000 gems less than the orbs.
250 Elite 5* Shards(1200)50 Orange Artifact Fragments(1400)Penny Skin(1600)10 Heroic Scrolls600I’d say that the Artifact > Skin > “Elite” 5*, but if you have absolutely no need for artifacts, and plan to use Penny, then the skin is a decent option. Only reason to go for the 5* is if you need to unlock the next Tier at the absolute minimum price.
350 Elite 5* Dark Shards(2600)Penny(2600)Amen-Ra Skin(2800)5 Prophet Orbs1800If you are whaling or saved up a metric ton of scrolls to complete the event all 4 times, I’d say the Amen-Ra skin is the winner. Evaluation of Penny is still up in the air, and the 5* dark hero is a crap shoot. If you have no interest in Penny I’d say roll the dice with the dark hero and worst case scenario you’ll have a Dark fodder.
4Aida(4500)Amen-Ra(4500)N/A20 Feathers4400It really comes down to preference here. Aida is in the meta and currently one of the most powerful Heroes in the game. Amen-Ra requires a bit more evaluation but seems strong at first glance.
5Wildfire Torch(6500)Punisher of the Immortal(6000)N/A30 Feathers8900Wildfire Torch is brand new and we need to evaluate which heroes it may do well on and how it may shake up the meta. Punisher of the Immortal is one of the best pure damage artifacts and well worth it if you can rustle up 15000 Koi. It seems especially suited to Penny, the new Fortress hero whose skills revolve around crit

Part 2.

Overall I’d say the first week was underwhelming. Not much effort put into the event at all aside from increasing the scrolls to complete an event loop (for unknown rea$on$). This week is somehow worse. In addition to the once more inflated event costs, the top reward from the event isn’t even the most recent or desirable light hero, there is no way to boost your Koi with gems, they removed the daily free Koi in the mail, the packages are pretty much garbage for value, and they put second mini-event in place which is ALSO way out of reach for anyone who hasn’t done some fairly heavy spending. Anyway, enough kvetching, on to the details…

A second type of currency was introduced with the second week of the event. In addition to Koi there are now Fishbone Coins.

As of right now, there are 2 ways to get Koi without paying.

  • Randomly dropped from collecting campaign loot (if this is like prior event drops, it will be around 200-300/day)

  • Rewards for hitting tiers of event completion (1200 per full completion using 100 orbs)

Total for the week you can expect about 1500 Koi from campaign drops. If you can spend 400 Prophet Orbs you can get up to 6,500 Koi without spending any money, but chances are most F2P or low VIP players will end up with 2000-3000 Koi for the week.

If you over-prepared and burned 2600 scrolls and 400 orbs, you would have likely ended up with barely enough Koi to get the artifact without dropping any cash, but I’m willing to bet only a handful of people in the entire game will be in that situation.

Fishbone Coins are straightforward. There are two flavors available, Gold and Silver. There is only one way to acquire each version. You can get up to 25 gold coins by acquiring 5* heroes. Any method will do. Claiming shards, summons, fusions, etc will give you a gold coin. You get a silver coin by spending a prophet orb (no limit).

Event Packages

There are two different types of package for P2P Players. Special event packages geared towards light/moderate spenders, and the regular packages aimed at whales.

There is one package is for light spenders, and an Aida skin package for moderate spenders.

  • $5 package: 666 gems, 6 Prophet Orbs, 10m gold, 100 Koi

Total value if you ignore the Koi is 3,366 gems or 673.2 gems/dollar. This is worse than the Monthly Senior Privilege Card (800 gems/dollar) but better than the Monthly Privilege Card (560 gems/dollar). If the 100 Koi or 6 Orbs helps you hit a major threshold its probably worth it for light spenders. Otherwise you can probably pass. This is the cheapest Koi/dollar (20) available.

  • $50 package: 2500 gems, 15 Prophet Orbs, Premium Aida Skin, 800 Koi

Total value if you ignore the Koi is 9,250 gems or 185 gems/dollar. This is a terrible value compared to either of the monthly cards. Hard pass for moderate spenders unless you’re in love with the Aida skin or desperately need the 800 Koi. The Koi/dollar ratio (16) is better than any of the value packages but worse than the other $5 event package.

The standard “Value” packages are for people with lots of money to burn. You shouldn’t buy these unless you need the Event Currency to hit a premium reward because the gem/dollar ratio is terrible. Each of these packages can be bought up to 5 times.

Spending Fishbones

There is no mystery to spending Fishbones. Gold coins give 4 points and Silver coins give 1 point. You need to get 500 points to get all the rewards. Since the gold coins cap out at 25, that means you’d need to spend 400 Prophet Orbs to get all rewards. This is a REALLY harsh cost compared to prior events. Most F2P or light spenders will only be able to get 100-200 points.

Spending Koi

You should probably wait till the last day of the event to make any Koi purchases. These rewards aren’t going anywhere till the end of the event. Use that time to learn more about the power level of the new heroes and see how many Koi you will have on hand after the campaign drops. You will be able to make a more informed decision about what to purchase if you wait. The first tier is a pretty easy Orb purchase at this point since the scroll half of the event has completed.

The top reward(s) for this event are premium artifacts, but it is highly unlikely you’ll be able to reach that level without spending a decent chunk of change. There are 5 tiers of rewards, each with 2-3 items that you could purchase. In order to unlock a higher tier, at least one item must be purchased from the tier below. You’ll also get a bonus reward for each purchase on each tier.

250 Elite 5* Shards(1200)50 Orange Artifact Fragments(1400)Penny Skin(1600)10 Heroic Scrolls600I’d say that the Artifact > Skin > “Elite” 5*, but if you have absolutely no need for artifacts, and plan to use Penny, then the skin is a decent option.

350 Elite 5* Dark Shards(2600)Penny(2600)Amen-Ra Skin(2800)5 Prophet Orbs1800Penny seems to be a super powerful hero and I’d say is the best option here. If you’re a whale who went nuts this event than the Amen-Ra skin is probably more up your alley. The Dark shards are more likely than not to end up as a dark fodder, so I don’t think it’s worth it over either of the other two options.
4Aida(4500)Amen-Ra(4500)N/A20 Feathers4400It really comes down to preference here. Aida is in the meta and currently one of the most powerful and versatile heroes in the game. Amen-Ra requires a bit more evaluation but seems strong at first glance, though useful in fewer situations than Aida is.
5Wildfire Torch(6500)Punisher of the Immortal(6000)N/A30 Feathers9900Wildfire Torch is brand new and we need to evaluate which heroes it may do well on and how it may shake up the meta.
