It's because any rod can technically work. It's all based on the fishing skill rather than explicitly what rod you use. Fishing skill is influenced based on things like time of day, moon phase, rod, bait, certain accessories and potions, as well as the depth and width of the water you're fishing in. Basically, the more fishing skill you have, the better chance of catching rarer fish. You need so much of it to reliably land Fishron, which is why while some people are right in that wooden rod can land him, it's not really a good idea to try because you'll waste worms more often than not
Yep, I guess thats how it works.
Once again, the wiki is kinda misleading for not mentioning any of this in the Summoning Duke Article...
Oh well. Gotta increment the Fishing power then!
