It's no secret that Final Fantasy XIV's Island Sanctuary is a game of gathering and crafting. The number of materials available on the island keeps on growing, and they all require different tools and methods to obtain them. Island Resin is one material that might have flown under your radar.
It's relatively easy to find Island Resin, so long as your Sanctuary Rank is at level 10 or higher. If it isn't, there are plenty of ways to level up quickly and to get yourself plenty of gil and goodies on the way.
While you won't find Island Resin in many crafts, the tools that do require it are essential if you want to max out your island. It's used for two separate mammet-sized tools, and you'll have to craft them if you plan to expand your hideaway. It's also used to craft one of your gathering tools: the Islekeep's Mythril Pickaxe, which you unlock pretty far into developing your island. Island Resin is something you may only need a few times, but you definitely need it when you do.
Where to find Island Resin in FFXIV
If you've spent time gathering, you've probably come across Tualong Trees, the node needed to collect from to get Island Resin. They're found close to the entrance to The Wilds after heading in and following the river east for a bit. There, you'll find the best place to farm Island Resin. You'll need to have the Islekeep's Iron Hatchet available from Sanctuary Rank 10 to gather it.

There are Tualong Trees on both sides of the river, and this area has the highest concentration of them on the map. You can find Tualong Trees all over the island, but they're much more spread out and tough to farm quickly. If you stick around the area above, you should be able to go around to each node in a quick circuit, getting them to respawn as you go.
If you're having trouble differentiating Tualong Trees from every other tree on the island, don't worry. To tell them apart, take a look at the curve of the trunk and the color and texture of the bark. These trees aren't straight; they curve and bend all the way up, and they fork into two main branches toward the top. As for their color, they look splotchy compared to other trees.
