Hello, I'm like 70 hours into the game and I've sort of made it my mission to completely cleanse this island of any monsters (and also any buildings, all must return to nature :p) so I've been doing the deadly transmission signal ASAP in any area I enter and clear it as much as possible. Materials seem pretty abundant so I'm wondering if there is any actual reason to bring the monsters back (other than possibly a harder challenge of course), such as "you won't get enough mana beads/some other resource if you don't" or maybe they give out some special loot that I wouldn't be able to get otherwise? I don't want to just create a lot of work for myself without having any idea about the consequences so if someone can tell me what this "ascension" entails I'd highly appreciate that. What do I gain out of doing this?
