Periastron Tower Defense shard spending centers entirely on purchasing Fragmented Crates from the lobby shop. In this Roblox card-based tower defense game developed by Periastron Champions, shards (referred to in-game interchangeably with runes) serve as a specialized gacha currency separate from standard gold coins. Players spend their accumulated shards specifically to chase high-tier Cosmic units while progressing their pity counters.
Where to Spend Shards in Periastron Tower Defense
Shards are redeemed in the lobby crate shop, where players can buy specialized boxes instead of spending standard coins. Video testing shows that shard inventory is dedicated to Fragmented Crates, which stand out from entry-level coin crates.
The primary draw of spending shards on Fragmented Crates is the drop rate for top-rarity cards:
- Fragmented Crates display a 1% drop rate for Cosmic units, making them the primary shard sink for players chasing elite cards like Necromancer.
- Opening Fragmented Crates actively builds progress toward the game's Cosmic and Legendary pity counters.
- The crate opening interface allows players to open crates in multi-pull batches (such as five or six at once) directly inside the lobby.
Crate Types and Pity Mechanics
The update introducing code redemption also added an official in-game pity system, but not every crate interacts with it equally. A system notification in the game specifically warns players about pity exclusions.
| Crate Name | Primary Currency | Cosmic Drop Rate / Tier | Counts Toward Cosmic & Legendary Pity? |
|---|---|---|---|
| Crate of Beginnings | Coins | Starter / Common pool | No (officially excluded by in-game alert) |
| Crate of Nature | Gold / Coins | Standard pool | Yes |
| Fragmented Crate | Shards / Runes | 1% Cosmic pull rate | Yes |
Because the developer explicitly configured Crate of Beginnings to not count toward Cosmic and Legendary pity, spending currency on the wrong crate wastes roll accumulation. Shards spent on Fragmented Crates ensure that every opened box contributes toward guaranteed high-tier pulls.
How Players Obtain Shards
To fund shard spending, players rely on a combination of in-game progression, crate recycling, and official bonuses:
- Crate Unboxings: Opening crates like Crate of Nature or lower-tier crates can award runes and shards as secondary drops when rolling for units.
- Community Codes: Promo codes released by the developer have included shards alongside coins. For example, redeeming the early "release" code rewarded 3 shards and 500 coins after joining the official Periastron Champions Roblox group.
- Store Game Passes: Players looking to accelerate shard acquisition can purchase permanent store multipliers.
