that last part sucks, he sounds fake, like he's trying to trick them and is bad at it

He could get something like the [Dimensional Mother Stone] from Shadow Hack. If he can gain complete control the space and whatever in it, he would be able to cover most of what the tree could offer.

you could have him sculpt puzzle boxes it should give him int. and/or wis. and may help in learning crafting skills

what if the caretaker was a real world npc, the Voice made her fell the spot of caretaker so no matter what happens she'll reboot, like the next morning she be back at caretaking

you can let him find DF that doesn't suit him and have Roger tell them about their power and weakness, then have his mother worried that being different would make things worse for him, so she tells him to have space pod check it out, then it depends on what the AI findings are, they may cover each other's weaknesses.

wasn't the (Usable 10 times per day) limit added after the event? if you don't show the devour skill in the event they shouldn't add it.

tree/plant they can take on animals forms the boss can be a dragon. they could have a connection with the ten tails

nono can upgrade his skin to feel underground and in walls

why? mc asked for walking dead so he should know what's going to happen why not walk in and save the horses

why not save the boy ? all you have to do is find and take care his mom on the way out
