Optimizing Durability Reduction Resistance
by Karpfen
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
- DRR from items
- DRR from fishing lifeskill level
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%.
DRR from items
The current maximum obtainable DRR from items is 91%.
For Shai characters this maximum is 81%, since she is missing an awakening weapon outfit skin, which would provide 10% DRR as Equip Effect.
| 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.
DRR from lifeskill level
Each lifeskill level will provide 0.5% DRR until the cap of 60% DRR 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
