Actually, just enchanting random rocks means that a human simply cannot sneak past goblins, as a precise ring of blue will flare up around his position.
Improving this spell, it could release flashes of light when humans approach, dulling their eyes to the presence of goblins in the dark.
A decent kernel of an idea, plainly written though, and needing some work - presentation, detail, verisimilitude. Also, the name is as if you named London "Imperial Capital 47", and Constantinople "Big City on the Bosporus". Go to Comment
As for the "same race" issue - if the GM and players make characters together, then often, they will be more compatible than the 'every man for himself' approach, where every player makes a PC and then try to fit them together. Likewise, then the approach 'you are all dwarves from the hold of Kazak Pwn' is viable.
Also, why would the PCs in #5 have to be of the same race? They could be from a town with a 50/50 human/gnome ratio, an elven enclave and a dwarven craftsman. Solved.
#10, nobility? An empire the size of Rome will have scores of races within its borders, and the nobility will represent it if it is egalitarian. Humans and elves already have no trouble marrying anyway, and with the wonders of magic, many weird unions become possible.
Along the same lines, #18 can see an extended family with a tiefling, half-elf, aasimar and half-dragon... and Harmandur the dwarf is adopted.
Actually, two linked portals can be placed below each other. The lower one covers a shallow pit with something desirable. Once you go in, you fall - from the upper portal into the lower one, and again and again and again... until you are rescued, or die. Go to Comment
Why so seriousss?
This carries a Joker vibe, and, in fact, can benefit from being acted out like him - a show of madness so ripe and thorough that not for a second you doubt his will to murder, his utter lack of conscience and sociopathic amusement at the misery of others.

Please, do not clutter the main site with a dozen half-finished "request advice" submissions. Usually, it is better to finish one thing, then start another. Also, the forums are perchance better suited to discuss submissions that are less than 90% finished. Go to Comment
