What runes?

could be better

Lol, there are 412 legendary monsters in this game. I'm assuming you're a beginner, which is great! Everybody is at some point. Don't worry too much about being competitive yet. Just continue to play, feeding and breeding what you can, upgrading your various buildings and habitats, and doing the best you can in each event. Eventually, you'll find you've got a great assortment of legendaries to choose from. Then you'll get a bunch of high level runes to put on them. And a bunch of ranked up relics. Do your best in PvP, but don't fret over it right now.

The reason I say all that is this: that might be a decent defense in a bronze league, but in Champion or Legendary leagues? Nah, you'd get destroyed.

This is good for bronze and silver leagues but no in gold and champion leagues.
