rotmg is really fast paced, you’re going to HAVE to rush to keep up, and to build up skill you’re going to try to rush hard dungeons just so you can have practice dodging better, or just for the thrill of it or maybe you’re soloing that dungeon
But that really only applies to most dungeons, maxing characters, on the other hand, it’s important to accumulate potions and gear that you can sell for potions that you do need, but make sure not to take things too slow - death happens for me around once a month, the way I see it the longer you take to do something the more it’s going to slip out of your grasp.
I’ve been trying to get a legendary pet for 5 months now, and I’m just playing casually. It ain’t working.
TL;DR Work towards your goal safely, but make sure to take risks now and then (going deep in tombs, shatters, etc), and dont forget your nexus button works.
