Spawner upgrades make a placed spawner faster, bigger or more rewarding. Three upgrades are available on Survival, each with two levels, and every level costs $1,000,000 per spawner in the stack, paid in money.
Opening the upgrade menu#
Right-click a placed spawner (or run /spawner panel while looking at it) and click Amethyst Shard Upgrades. The item shows
Levels owned: x/y; a Clock clock means a purchase is still being confirmed. In the Spawner Upgrades menu each upgrade shows:
- the current level and the next level,
- the current effect and the next effect,
- the cost for the whole stack and its currency,
- its status: Available, Maxed or Pending.
Click an available upgrade to buy its next level. Chat confirms <Upgrade> upgraded to level N. If you cannot pay you see You cannot afford that upgrade.; if the offer changed after the menu opened you are asked to reopen it. Only the spawner's owner can buy upgrades. The summary item below the upgrades shows the stack size and the upgrade levels owned, as a reminder that every upgrade applies to the whole stack.
Pricing#
An upgrade is bought for the whole stack and is charged per spawner in the stack: with 64 spawners stacked, one level costs 64 times the level price. Price examples for a Spawn Speed level:
| Stack size | Cost of one level |
|---|---|
| 1 spawner | $1,000,000 |
| 10 spawners | $10,000,000 |
| 64 spawners | $64,000,000 |
Upgrades are stored on the placed stack. Adding unupgraded spawners to an upgraded stack makes you pay for the difference: see Spawner Stacking.
Spawn Speed#
Shortens the time between production cycles. The base cycle is 30 seconds and the new interval is the base divided by the multiplier.
| Level | Effect | Price per spawner |
|---|---|---|
| 1 | 1.25x speed (24 second cycle) | $1,000,000 |
| 2 | 1.5x speed (20 second cycle) | $1,000,000 |
Spawn Amount#
Multiplies how many mobs the spawner adds per cycle. The mobs added per cycle are the stack size times this multiplier, up to 32 per cycle.
| Level | Effect | Price per spawner |
|---|---|---|
| 1 | 1.25x mobs per cycle | $1,000,000 |
| 2 | 1.5x mobs per cycle | $1,000,000 |
Drop Chance#
Increases the drops of every spawner mob you kill: each item it drops has a chance of dropping one extra copy. At level 1 (1.25x) the chance is 25%, and at level 2 (1.5x) it is 50%.
| Level | Effect | Price per spawner |
|---|---|---|
| 1 | +25% drops (1.25x) | $1,000,000 |
| 2 | +50% drops (1.5x) | $1,000,000 |
Upgrades that are not available#
The spawner system also has Virtual Production, Auto Sell, Storage Capacity and XP Capacity upgrades. They are switched off on Survival, so they do not appear in the upgrade menu.
