Data

Outpost Defense

Outpost Defense passively generates Credits, Battle Data, Core Dust, and commander EXP at all times. You can also do up to 11 wipeouts a day to collect extra Outpost Defense rewards with gems.

Rates & wipeout costs

Outpost Defense produces 24 hours of rewards per day on its own. Every wipeout pays the same 2 hours of production, and the first one each day is free. After that, each wipeout costs more gems than the last.

Wipeout #	Gem cost	Production (hrs)	Hrs / gem

Events

Paid Story Event entries provide 0.200 Core Dust hours per gem. The five-week cycle below costs 2,300 gems, averaging about 65.7 gems per day. A few cheap Dispatch reroll upgrades do better, but only for about 2 gems a day.

This page uses a five-week cycle: one 2-week event followed by one 3-week event. Buying every entry bundle costs 2,300 gems. The cycle includes 175 free entries and 115 purchasable entries, for 796 total Core Dust hours when every paid entry is farmed on Hard.

Five-week cycle

One 2-week event plus one 3-week event. Free entries include first clears and repeat farming; paid entries assume every shop bundle is bought and farmed on Hard.

Cycle length	35 days
Free entries	175
Purchasable entries	115
Gems to buy every entry	2,300
Dust from free entries	336 hrs
Dust from paid entries	460 hrs
Total dust	796 hrs

Entry shops

Every event sells extra entries through one of two fixed shops. 2-week events use the 45-entry ladder. Every other event, including the 3-week Grands and the long one-offs, uses the 70-entry Grand ladder. Rows are listed the same way the in-game shop sells them, and duplicate-looking rows are distinct shop items.

2-week shop

Entries	Gems	Bundles
5	100	×2
5	100	×1
10	200	×1
20	400	×1
45	900	×5

5	100	×2
5	100	×2

Both ladders price every bundle at 20 gems per entry.

Dispatch

Reward probabilities for Normal and Collection Item Dispatch.

Reward tables

Each slot rolls independently. “Chance per slot” is the final chance of receiving that reward, and each table adds up to 100%.

Normal Dispatch rewards

Normal Dispatch has 10 slots. Box amounts are hours.

Common Shop

Credit and Core Dust drop chances, prices, and refresh costs in the Common Shop. All numbers were recorded from the game.

Slot probabilities

The shop has 10 slots, but only slots 1 to 3 can roll the Credit and Core Dust rewards below. You get two free pages each day: the daily shop page and the first refresh. Further refreshes cost 100, 200, 300 gems, and so on, with no cap.

Slot 1

Reward	Chance	Price	Note
30 raw Core Dust	1/3 (33.3333%)	Free	raw amount, not hours
60,000 raw Credits	2/3 (66.6667%)	Free	raw amount, not hours

Expected from two free pages: 80,000 raw Credits and 20 raw Core Dust per day.

Slots 4 to 10 never hold Core Dust. They sell miscellaneous items, and none are recommended (slot 5’s Profile Custom Packs are cosmetics, so buy them only if you’re into that).

For comparison, event stage entries convert at 0.200 hrs/gem and the first paid Outpost Defense wipeout at 0.040 hrs/gem for Core Dust. Credit-case rates answer a different resource need and should not be compared directly with those Dust rates.
