We were playing the RTL campaign last night, and this new dungeon level from Tomb of ice was level 1 of the dungeon the heroes entered.
The campaign is still in copper, my eldritch creatures are at silver level, and I think the campaign stands at about 36-26 for the Overlord.
My heroes (an experienced bunch) have come to the conclusion that this dungeon level is impossible (I think it is #42 or something, don't have the card handy)
Anyhow, it is the dungeon level with a Master shade, and I chose to spawn 3 lesser shades and a Master dark Priest. The map uses the new large 10x10 square tile, but the outdoor side, with the trees. The first problem encountered is what happens with a wraith in a tree? I used some common sense and said that the map was not designed to be impossible, so a wraith in a tree would only get its inherent ability (ghost) and not the shadowcloak ability from the tree. So that was fine..
Now the way the dungeon level is worded, is any time a hero enters a tree space, he immediately suffers 2 wounds, and his turn ends. ouch. Now the layout on this tile, is that from where the heroes would enter, they are immediatly blocked by trees. the only route is a single lane south, which leads into snow/ice. Hence they would roll a black die to see if they slip and stumble, ending their turn. The dungeon level card also says explicitly "heroes who enter a tree space....".. hence my wraiths and dark priest can spend the 2 movement to move into a tree space and continue moving. So the master wraith (any hero within 4 spaces of her at the start of the overlords turn takes 1 damage), can basically move around the map, keeping trees and ice between her and the heroes'. A friend counted the individual empty squares on the tile, and said there was something like 20 squares that did not have a tree, or snow/ice on it. There is also a spot in the top right corner which is a dead end surrounded by trees, and the only way in is through snow/ice tiles. And with the master wraith having pierce 5, ending your turn near her is certain death. And that's not taking into account the other 3 wraiths and the master dark priest.
Were we doing something wrong on this map? My heroes fled and only lost 2 of their number. If they stayed I know they would have been decimated over and over again. Oh.. and the master wraith has undying too.. nice... How are they expected to have a chance on this one? Even if they were buffed out, with gold weapons, my wraiths would always be able to move through the trees and keep my distance from them, whereas they would inevitably end their turn prematurely in a tree or ice..
