For any newer or some older players, I have some advice.
1. Don't be afraid to solo dungeons! Dungeons are not as scary to solo as you might think. If you think about it, they're actually like regular quests. Except you can't do them in many days, but in one.
2. Side worlds & side quests = important! Who cares if you're level 47 in Marleybone? It might be a bit embarassing to be such a high level in a world meant for 35 below, but It will be really easy for you, and you'll just fly through gameplay in a matter on months!
3. Looks are not important; neither is having a great castle! Most players who are on their first wizard and are under level 50 dress to impress, and don't care if they die a lot of times. Do. Not. Do. This. The important thing is STATS. And if you're buying a castle with crowns, think again. Buying armor is more worth it.
4. Be in a good mood. If you're in a really bad mood, w101 isn't going to make it better honestly. If you just came home from school, in which you got, let's say, three Fs, dying and "failing" in w101 isn't gonna make you feel better.
Alright, these are all so far. I hope it helped, at least a bit.
