What you get from salvaging Blunder Bomb (Salvage and Repair Station)

Blunder Bomb can be salvaged. Salvaging it gives the following items.

• Scrap Parts×1
• Blasting Dung×0-1
• Scarlet Bar×0-1

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.

* "Chest (Azeos' Wilderness)": provisional names. The in-game name has not been confirmed, so this site named the source after its internal name in the drop tables.

"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.
