Upgrade Trees
Experience
This upgrade tree adds .002x to your fishing xp (amount of Experience received per caught fish) multiplier. It can be upgraded 1000 times for a total fishing xp multiplier of 3x upon reaching level 1000.
Merchant
This upgrade tree adds .002x to your money (fish sale price) multiplier. It can be upgraded 1000 times for a total money multiplier of 3x upon reaching level 1000.
Luck
This upgrade tree reduces the chances of catching the most common fish rarities. 0.02% is added to the Luck unit per level. Rarities are decided from a random number between 0 and 100
| Fish Rarity | % Chance to Catch |
|---|---|
| Mythical | random number between 0 and 1 (1%) |
| Legendary | random number between 1 and 5 (4%) |
| Epic | random number between 5 and 15 (10%) |
| Rare | random number between 15 and 45 (30%) |
| Common | random number between 45 and 100 (55%) |
Each level of Luck is multiplied by .02. The equation to find the "Luck variable" is LV = (player Luck level *.02). If you were to have the maximum Luck of 500, then 500*0.02 = 10. This LV is then factored into the fish rarity calculation to increase the chances of catching higher rarity fish, while decreasing the chance of catching lower rarity fish. The LV is then multiplied into the rarity calculation with the following proportions.
| Fish Rarity | % Chance Increase |
|---|---|
| Mythical | LV*0.4 |
| Legendary | LV*0.3 |
| Epic | LV*0.2 |
| Rare | LV*0.1 |
| Common | 0 (Doesn't increase) |
The % Chance Increase is then added to the original % chance listed in the Rarities List. With 500 Luck, you would have a LV of 10 yielding the following percentages at the highest level.
| Fish Rarity | % Chance to Catch |
|---|---|
| Mythical | random number between 0 and 5 (5%) |
| Legendary | random number between 5 and 12 (7%) |
| Epic | random number between 12 and 24 (12%) |
| Rare | random number between 24 and 55 (31%) |
| Common | random number between 55 and 100 (45%) |
Prospect
This upgrade tree increases the chance of a shard being caught as bonus loot by 0.05% per level. The default chance of catching a shard in any zone is 1/60. The 0.05% per level reduces from the base number of 60, so for example, one level of Prospect uses the calculation: 60-(60*0.0005). After that, it selects a random number between 1 and the reduced number (59.97), and if that number is between 1 and 2 it gives the shard. This means that if you have 500 levels of Prospect (60-(60*500*0.0005)) = 45 the random number selection would then be between 1 and 45.
Double-up
This upgrade tree increases the chance of catching 2 of the same rarity fish on a single cast by 0.01% per level. It can be upgraded 250 times for a total Double-up chance of 2.5% upon reaching level 250.
Scale
This upgrade tree increases the chance of catching higher tier fish categories by 1 "Scale variable" per level. Fish category is calculated from a random number generator out of 5000.
| Fish Category | Chance to Catch |
|---|---|
| Gigantic | random number between 0 and 1 (0.02%) |
| Large+ | random number between 1 and 150 (2.98%) |
| Large | random number between 150 and 500 (7%) |
| Adult | random number between 500 and 2000 (30%) |
| Juvenile | random number between 2000 and 4000 (40%) |
| Baby | random number between 4000 and 5000 (20%) |
Large+ fish are displayed as Large in the game. Large+ fish have a higher possible length and weight than Large fish.
Each level of Scale as added to increase the catch chance. The equation to find the "Scale variable" is SV = (player Scale level*0.02). If you were to have the maximum Scale of 500, then SV = 500*0.02 = 10. This SV is then factored into the fish category calculation to increase the chances of catching higher tier fish, while decreasing the chance of catching lower tier fish. The SV is then multiplied into the rarity calculation with the following proportions.
| Fish Rarity | % Chance Increase |
|---|---|
| Gigantic | SV*(0.05) |
| Large+ | SV*(0.5) |
| Large | SV*(0.4) |
| Adult | SV*(0.4) |
| Juvenile | SV*(-0.4) |
| Baby | 0 (Doesn't change) |
The % Chance Increase is then added to the tiers out of 5000 value from the Tier List. With 500 Scale, you would have a SV yielding the following percentages at the highest level.
| Fish Category | Chance to Catch |
|---|---|
| Gigantic | random number between 1 and 26 (0.52%) |
| Large+ | random number between 26 and 425 (7.98%) |
| Large | random number between 425 and 975 (11%) |
| Adult | random number between 975 and 2675 (34%) |
| Juvenile | random number between 2675 and 4450 (35.5%) |
| Baby | random number between 4450 and 5000 (11%) |
Progression
This upgrade tree decreases the amount of time spent reeling in a fish during the fish catching minigame. By default, the player reels in any fish at a speed of 0.5 reel speed units per tick and this upgrade increases that speed by 0.1 per level for a total of 1.5 reel speed units including the base speed of 0.5 upon reaching level 10. 1.5 reel speed equates to a 3x decrease to reel in time compared to the default speed during the fish catching minigame.
Discovery
This upgrade raises your chance of obtaining a key when you fish by 0.005%, the chances corresponding to which key you obtain do not change with this upgrade. At the max level of discovery (500) your chance to obtain a key is 2.5% (1 in 40 fish).
If you successfully pull a key based on your discovery level, the key type is chosen according to the table below.
| Key | Chance |
|---|---|
| Marine Key | 90% |
| Pirate Key | 9% |
| Abyssal Key | 0.9% |
| Kraken Key | 0.1% |
Trophy Chance
This upgrade tree increases the chance of hooking a trophy fish by 0.05% per level. The default chance of hooking a trophy fish is 1/15000. It can be upgraded 100 times to increase the chance of hooking a trophy fish to 1/14250
