• Sanctuary Shop: the source's own framing is to buy Raven Essence there every week without fail — called the highest-priority recurring purchase.
• Expedition Shop: Gear Chests and Raven Fruit, described as cheap enough there to be worth buying regularly.
• Alliance Shop: Raven Essence and Gear Blueprints.
• VIP Shop: the source explicitly advises against spending large amounts of diamonds on Essence there for F2P/low-spend accounts, calling it poor value compared to the other three shops.

The same source's other claim — save Raven Gear Chests specifically to open on Alliance Duel days — isn't included here. It doesn't match anything already confirmed about how Alliance Duel scoring interacts with gear chests, and reads as plausibly conflating chest-opening with a points buff rather than a real gear-specific bonus. Flagged as unadopted rather than silently dropped.

Pack contents and prices may have changed since — store offers are exactly the kind of thing that drifts over patches, so treat this as a snapshot rather than current truth.

The source's own framing: prioritize value and long-term progress when spending, rather than chasing whatever pack is in front of you.

VIP Freya (Survivor)

Freya is a purchasable Survivor who grants a permanent bonus and a Rare Reward Chest on completing the daily Falcon Quest — see the Falcon Quest Planner on the Tools tab for what that quest is. The source frames a specific low-spender path to her:

A 6-day limited event. 12 Dwarven Pickaxes are given free daily via quests; each pickaxe spent is one dig, giving exactly one random reward — no multi-rewards, nothing carries over between digs. Floors 5, 10, 20, 30, 40, 60, 80 and 100 give extra progress rewards on top of the normal dig reward. The odds described below are identical from floor 11 through floor 100; the event allows digging up to floor 200.

How a dig is decided

Every dig is a weighted pull between a Normal reward and a Special reward. The Normal weight never changes — it's always 10. The Special weight climbs with how many times you've dug on your current floor (this resets to 1 on a new floor), and your chance of Special on that dig is Special weight ÷ (Special weight + 10):

The pity floor

Separately from the rising weight above, every floor has a guaranteed Special dig count based on the floor number's last digit — hit that dig count on the current floor without having rolled Special yet, and the next dig is Special for certain:

Pattern by last digit: floors ending in 1 or 6 → 5 digs; ending in 2 or 7 → 6 digs; ending in 3 or 8 → 8 digs; ending in 4 or 9 → 5 digs; ending in 5 or 0 → 10 digs.

Worked example — floor #3

First dig on any new floor always starts at Special weight 1 vs. Normal 10, i.e. 1÷11 ≈ 9%. Floor 3 ends in "3," so per the table above it's guaranteed by dig 8. If you keep digging on this floor without hitting Special early:

Note dig 8 is a pity override, not the weight-table's 75% row — the weight climb only reaches the 9+ tier (30 weight, 75%) on floors whose pity count runs past 8, e.g. floor 5 or 10 (guaranteed at dig 10).

Each spin costs diamonds or comes free daily, and pulls award Cynthia/Jester shards (plus occasional bonus shards from luck). The advice below is consistently invest only in Cynthia long-term — Jester is described as not worth the investment over time, even though both heroes share the same shard pool.

The Light Spender shard figure (~40 from 70 spins) isn't a clean 1:1 spin-to-shard ratio like the F2P row, and the source doesn't explain the conversion — reproduced as given rather than inferring a formula that isn't stated.
