I'm on the guild discord (not that I use it). An arena channel could be neat, if it was active and on-topic.
If I joined, half the discussions I would derail to be about Evvie or some other zany character idea. Or talk about my Zelda Breath of the Wild obsession. I swear the game is harder than dark souls unless I changed my play style and went around getting ingredients to craft a bunch of good food to boost my hearts and stuff. Even at 6 hearts a large number of enemies one hit kill you or at the very least take you down to extreme danger. Now that I'm at 9 I can still get obliterated in 2 attacks easily unless I go to the weakest enemy variety, who do more like half a heart damage to me now.
