Fishing in Terraria is actually a lot easier to do than most people realize, and the benefits of fishing are many, especially in pre-hardmode. It's possible to skip mining for armor and weapons almost entirely. You can get a pick axe with 100% mining power, weapons, loot crates, mounts and more.
Check out my Terraria Ranger let's play! Myself and some friends have lots of fun and give informative tips and tricks as we play (when we aren't busy goofing off).
Fishing was added to Terraria in the 1.2.4 patch for PC. It is currently not in Consoles or Mobile at the time of this video release, but is planned to be added soon so you can all look forward to fishing if you aren't on PC!
If you have any questions about the Angler, how to build a lake where there isn't one, or anything else, please let me know and I'll be happy to answer to the best of my knowledge. If you guys really want a video of me showing how to build a lake of honey, lava, water, etc. even on a floating island I can show you how, just let me know in the comments below. Be sure to like and subscribe! It really helps me get promoted.
You guys rock. :)
