How do you lay traps effectively?
1) Do you set them up where the monster is going to appear (i.e. lich's spawn spot)?
2) Do you set them up on top of a monster during battle?
3) Do you set them up before a battle and try to get the monster to walk on top of it?
4) Do you set them up one on top of another, or next to each other?

Get a rating of about 100 and then watch the bullets fly.

You can lay them anytime there are no red (hostile) creatures are around. People have documented that they are effective against certain large winged lizards.

I laid them all around some blue charcters I had been warned (in game) would ambush me. When they turned red the traps activated and killed about eight or more enemies, wiping them out in a shockly quick instant.

I have no idea whether they work against Liches. Try it.

I'm pretty sure the traps work on vicinty rather than someone walking on top of it.

Hope this helps a little G.W.

Oh yes, traps works on Liches. It helped me to be victoriuos in on of the thoughest battles in the game. And I think most of you know what battle Im talking about... So Im eternally thankful to Jan and his trap abilities.
