Rune of Marking
 

Fix it or remove it... As it stands... people just cast it all over the place as an annoyance and pretty much is a form of pollution... right now I am walking around in the mines and I see them up on the walls everywhere...

They are also fun while sailing - the ship stops when it hits one, and I've seen regions 'mined' with them to make it virtually impossible to get through...

1. The runes break playermade ships...
2. Fun? FUN!??! They're annoying as hell!! Put yourself in the sailor's shoes and say it's fun!

I apologize for being sarcastic. I was sailing when I encountered said region, I think it was near Forest.

If you want something to damage ships and make it more dangerous maybe add floating cannonballs so sensetive they blowup and damage the ship. Of course the cannonballs would have to slowly blow up overtime...

You can always take them down with magic missile or missile swarm.

Some kind of sea mine would be nice for seabattles and protection of forts, maybe selective for different kingdoms' ships, but I don't think people intend to use the rune that way - they just want to annoy...
