1) Braziers, build lots of them.
2) Destroying the trial by fire.
3) Plain ol' going up to the raiders and pvping them. Risky me thinks.
4) Using alts to repair walls they've destroyed trapping them in to be picked apart by brazier fire.
4.5)
5) Because skeltons are immovable for the first 30 mins you can log on alts and kamikaze a raider into a corner. Again the point is to trap the raider. (From viewtopic.php?f=6&t=5546)
What did I miss, is there anyone who can elaborate on any of those options from the point of a defender? From the point of a raider?
I have a couple of ideas myself that I'd like to put forward and maybe get some constructive criticism or here from someone who has already thought of them and tried them out.
6) The Alt Trap
The idea here would to be to create a "weak spot" for the raiders to "exploit". The gist would be to create a strong wall with a single space gap in it. Then log off an alt in this exact spot. After a raider passes through the opening, thinking they had found an easy way in you log your alt on and have him be killed in that opening, creating a skeleton that would effectively trap the raider inside.
Here's one possibility of how one could pull it off.
I guess I might as well add, the alt trap idea only works if your are online during the raid, they become counter productive if you're not. So they are probably better for towns than small p-claims.
Variations on a theme
7. Animals
I read some thread about someone aggroing a bear into Boston, in theory you could aggro a bear or snake towards the raiders.
I'd imagine a slightly better idea would be to aggro a bear or a bunch of snakes in between your walls. I have no idea if that would work of course, can animals trespass? Would they stay trapped or randomly disappear after a while? Would a snake bite compound with the drain from trespassing? I can't really imagine anything more badass than having a wall of bears, other than maybe riding one...
