For the longest time now, I've wanted Betta more than any other monster. Somewhat unrelated, today I got my first legendary scroll. It was from the shop pieces, I'm in the process of getting the one from the event currently. I open the scroll, very eagerly. And I see what looks like a red tail swaying in the air. When the four-star symbol fades I scream out loud to see I got myself a "Fire Betta." This is literally my second choice in "If you could have any monster." Now my question is what she's used for. PvP, PvE? Also what are some rune recommendations? I've seen violent/swift, energy on most people, but I'm curious if anyone has experience with other sets.
