Elona is a very specific one, can't even count it as a roguelike, more like a massive-massive sandbox. Can't blame you!>>1924
Wu Jian? The one which allows you to jump from walls and slash everything around you? He's my favorite, he's essentially just a movekit for very stylish executions and doesn't limit at all unlike other gods.>>1926
Whenever you die - try to think about what you could have done to prevent that death. Whenever you feel like your character is having troubles with creatures of your "level" think of what part of your build could have been prioritized more to help you out. Generally you want to find the silver line between broad skillset and narrow expertise to be able to respond to any kinds of threats with decent skills.
Although this advice is mostly for adom, the other two games you played are so specific and I don't have enough experience with them to help you.
