The High Test Fishing Line is an accessory with a 2.5% (1 in 40) chance of being awarded by the Angler for completing a quest. While equipped, it prevents fishing line from breaking while fishing. Without the High Test Fishing Line equipped, there is a 1 in 7 chance that the line will break on any reel-in that was supposed to yield a catch.
On the 電腦版, the Angler will not give the player a High Test Fishing Line as a reward if they already have one in their inventory or in any of their Portable Storages. However, if the player has a High Test Fishing Line, Angler Earring, and Tackle Box (or they have the accessory crafted from them, the 漁夫漁具袋) in their inventories, he will be able to give the player duplicate High Test Fishing Lines.
