There is legit no reason for anybody to go inside the Gingerbread realm to fight the Gingerbread user (it’s not even good as an escape tool like unmastered Portal). Even while inside you don’t have any buffs to yourself so that’s an even bigger reason why nobody uses the Gingerbread realm when fighting.
Here’s how to make players incentivized enough to invade the realm:
Clone Possession:
Sitting on the clone now allows you to possess a random Gingerbread soldier. You gain abilities according to what type of soldier they are. You can control them to walk out of the Gingerbread house to enter the main world as long as the Gingerbread house stays in tact. The house basically works like a link between the main world and your realm. Once the link is severed the controlled Gingerbread soldier outside of the realm dies.
You can control the Gingerbread soldier to fight other players and if the soldier dies, you get evicted from your throne immediately. Sit back on it to control a different soldier. This way you can force players to invade your realm if they want to stop you from sending Gingerbread soldiers at them.
In order to stop possessing a Gingerbread soldier just press E again. Jumping shouldn’t make you get off the throne as jumping is quite necessary for pvp. In addition, you can also do /e kneel as a Gingerbread soldier if you want to make them kneel in front of you on your throne.
The number of Gingerbread soldiers increase more and they’re spread out around the realm more.
Robot users can send only their clones into the realm while the main body stand outside and the clones will always target the Gingerbread the user as long as they’re still inside the realm. Army users can do this too if they punch the house so that Gingerbread still had counters.
Technically other players who sit on the throne can also control a Gingerbread soldier so now you get to fight alongside your soldiers as well.
