Optimizing Durability Reduction Resistance (DRR)
How does DRR work?
Each time you cast your fishing rod there is a chance to consume durability on your gear (rod, chair, float).
There are three separate parts that can affect this chance.
- Brand Stone
- Item DRR
- Life Skill DRR
These three factors are multiplied together to form one final chance to consume durability.
Brand Stone
An Item Brand Stone will reduce your chance to consume durability on the branded item by 50%.
Item DRR
The current maximum obtainable Item DRR is 91%.
| Item | Durability Reduction Resistance (DRR) |
|---|---|
| Pets (4x T4, 1x T5) | 21.00% |
| 8-Piece Outfit Set Effect | 10.00% |
| Mainhand Weapon Outfit | 10.00% |
| Awakening Weapon Outfit | 10.00% |
| Blacksmith’s Blessing | 30.00% |
| Lil’ Otter Fishing Carrier 🦦 | 10.00% |
Pets
When getting pets for a DRR setup, you need to look out for their Talent.
There are a few pets which can have this DRR talent combined with the Special: Auto-Fishing Time Reduction.
Here are some other pets with just DRR talent:
| Premium Pets | Rare Pets |
|---|---|
| Young Griffon | Snowlight Lynx |
| Turtle | Snowkid |
| Stoneback Crab | Borrum Wolf |
| Desert Fox | Young Fogan |
| Erethea’s Snow Leopard | |
| Helter-Skelter Ceros |
❗Some pet types are different on other regions, so make sure to check them before purchasing❗
Life Skill DRR
Life Skill DRR is 0% while untrained. At Beginner 1 it becomes 10%, then rises by 0.5 percentage points per progression level to the 60% cap at Guru 20.
Calculating Chance to Consume Durability
Let’s say you have the following setup:
- Unbranded Rod
- Guru 20
- 91% DRR
This will put your chance to consume durability at 3.6%:
(1 − 0.6) × (1 − 0.91) = 0.036
Adding a Brand Stone to this puts our chance to consume durability at 1.8% (exactly half):
0.5 × (1 − 0.6) × (1 − 0.91) = 0.018
Calculating Average Casts
How does this look like for the Grandpa Cron Rod?
It has a maximum durability of 2000. So with a chance of 1.8% this will give us on average ~111111 casts:
2000 / 0.018 ≈ 111111.1111
Without a Brand Stone it will be only 55555 casts, so make sure to brand it!
2000 / 0.036 ≈ 55555.5556
