What you get from salvaging Corrosion Staff (Salvage and Repair Station)

Corrosion Staff can be salvaged. Salvaging it gives the following items.

• Scrap Parts×20
• Tin Ore×3-5
• Ancient Gemstone×0-2
• Ground Acid Slime×1-3

For each material, the amount is "amount used to craft × 0.49 (lower when durability is down, 0.3 at 0 durability) × the item's multiplier", and a fraction is the chance of one more (2.4 means 2, with a 40% chance of 3). The range is from 0 durability to full durability (items without durability always count as full). Scrap parts are a fixed number set by the item level. All items that can be salvaged are listed in salvaging.

How to get Corrosion Staff (Fishing, Boss drop, Enemy drop, Chests & pedestals, Breakable objects)

Fishing (1) Boss drop (1) Enemy drop (1) Chests & pedestals (1) Breakable objects (1)

Source	Type	Biome	Amount	Chance
Fishing in The Clay Caves (non-fish catches)	Fishing	The Clay Caves	2–4	0.66%
The Hive Mother	Boss drop	The Clay Caves	1	8.3%4% from the guaranteed group, 0.91% per regular roll
Big Larva	Enemy drop	The Clay Caves	1	0.5%
Larva Hive Chest	Chests & pedestals	The Clay Caves	1	7.3%
Hive Growth	Breakable objects	Larva Hive	1	2.2%

"Chance" is the chance to get at least one of this item per try (opening one chest, defeating one enemy, one catch). A "guaranteed group" is the group of a chest or boss from which exactly one item always drops; it does not mean this item always drops (the chance of it being picked from that group is shown in small text). Only items that always drop are marked "Guaranteed". Fishing means catches with a fishing rod, separate from enemy and boss drops. Calculated from the game's drop tables (Conf/Loot, 1.3.0.6) the same way the game rolls them.
