Too long didn't read.
the uhh.. ability to swim is something that has been suggested before as just deepone in general but it would require total map redesigns theres other things i could comment on but its quite late so i will probably just make comments over time with stuff to say as far as like slaver thing is concerned i suggested that over a year ago in the suggestions this is actually enough stuff to justify joining the discord which you can find in your downloads as roomlinks.zip
I think the main issues for me here are the development of the magician and the evolution of the race. For the second question, I found threads on the forum. As for the magician, there is a real shortage here. There is, of course, brewing potions using a cauldron, but this is Science, and not something that requires Magical Abilities. According to the lore, magicians in the game can make Staves from improvised means. An example, as I already translated above, is the Staff of Mud, which is literally made of shit and sticks. But it works, and that's obviously not what an advanced lab is for. Cokona, this cutie made a staff from her own hand. Cokona is far from a professor of Magic. But she did it. So, I think the minimum Crafting Staff is worth adding. Since it’s obvious that this is easy to implement game-mechanically + it will strengthen the connection between Lore and Gameplay. For good measure, this should be crafting something simple like the Staff of Mud. You can also add something new, of a similar type.
