A cute idea could be to allow demigods the ability to place encounters down in others realms.
Say they have a designed encounter were they are given customization options like the ones here. From here, you could save the settings as a file called "Epic wizard who needs to be killed by a magic sword' encounter.
This encounter could consist of 'Only AI' options as opposed to being required to have guild members.
Players, while exploring realms, could then find these encounters in there exploration and activate them. The rewards would get sent directly to your limbo account (so your not worrying about game balance) and players could choose to invade, if you have the option on.
Might be a fun way to incorporate some exploration, and give demigods something fun to do as they explore realms.
You might be able to spark some community interest in this stuff, and give them another reason to go in realms.
When a demigod or god makes there special encounter, they can choose whatever tile they're on, place the encounter, and then have realm moderators quickly look over the encounter and it's place on the realm map, and decide whether or not to reject it.
Just spitballing, might be a fun way to include this guild activity/demi god stuff in a way that overlaps with realms.
Ideally, the demigod would have this option available in their 'meta spell' menu. xD
You could have an option for players to opt out of these types of encounters if they want to.
side note: what about spell totems? what if there was an option to place those in this game. Just have:
Elf Village totem tier 1 (basic), tier 2 (basic plus spells), tier 3 (advanced training + spells) which could be in the place of were you'd select AI skill level.
Was always curious what it'd be like to have some totem on totem action, limited spells with a starting batch of troops.
