Trust me, even though I want to ascend Tighnari as fast as possible, I've been so into Dendro reactions that I cannot make up some time for it. But worry not! That's not gonna happen with you. I'll share my personal strategy to farm for materials and ascend a character fast so that you can get your Tighnari to the maximum level. Alright, first things first, recently the friend limit has been increased to 60, which means you can co-op with other people or make new friends. So, hop onto other people's worlds and ask them whether you can farm in their world. Not everyone will have Tighnari, so there are chances that some of them would let you farm in their world, and you can easily grab a bunch of them. Another tip is to mark the locations of lotuses on your map so that you don't have to open the online map again. Once you dive into a friend's world, you can teleport to the pinned locations and efficiently save your time to farm.
