Epheria Fishing Rod
The Epheria Fishing Rod can be crafted at a Level 3 Tool Workshop. The Required Materials are:
Birch Timber (1)
Steel (2)
Pure Iron Crystal (5)
Monk’s Branch (9)
Black Stone Powder (15)


The Epheria Fishing Rod can be upgraded with Blackstones (Weapon), succeeding for the first time will increase the max durability from 50 / 50 [50] to 50 / 50 [60]. The upgrade can also fail and you will lose some of your maximum durability.
Which means you will have to repair it at a blacksmith by using another Epheria Fishing Rod.
The normal durability loss can be repaired at the Blacksmith for some silver.

For those interested, each enhancement gives +10 durability. Remember to keep some extras for repairs though so that you can make money back for the investment by making use of a fully repaired Epheria. The other option is to purchase the rare enhanced versions on the marketplace as they can only be listed when completely repaired and are typically much cheaper than if you did it yourself.
