I've finally gotten the runes system into a state fit to publish. You'll find it at the shiny new button in the top toolbar. Before you go and add all 300 runes in your inventory, though, I'd like to say that a rune optimizer is a very, very long ways off. I'll personally only be adding runes that are currently assigned to my monsters for the time being.
Runes can be managed from the runes section or the individual monster view. You can directly assign a rune to a monster when creating it from scratch, or create a rune from the monster view page.
UPDATE: Rune import/export feature is live. Access it from your rune inventory page. More import/export features are coming soon like detect duplicates and import/export monsters.
Monsters from the latest patch have been added. As always I am missing skill level-up details and awakening essences. If you have this information please leave a feedback.
All of the monsters from the patch have been added! As usual, I am missing the max skill level and level up description for most of the new skills. If you summon one of the monsters I am missing the description from please leave a feedback! Be sure to include each line of the level-up text.
Missing skill level-up description text:
You can now delete your account. The link is accessible by clicking on your username and going to Edit Profile.
After you confirm the verification that you do want to delete your account, all of your information, monsters, teams, and any other data is immediately deleted. There is no chance of recovery and I will not accept requests to restore accounts from backups.
One popular feature request was some sort of way to have friends or a list of other people's profiles. I've added a twitter style following system. There is no public directory of users, though, so to follow someone you need to have a link to their profile. On their page you will see a button to start following them. Only public profiles can be followed, but if you have a private profile you can still follow public profiles.
You can view the list of people you're following with the new button next to your username, and also see who is following you (if they are public).
