[QUOTE="Balesir, post: 6208262, member: 27160"] Water blocking LoE must be a houserule, since only blocking terrain (which blocks movement) blocks LoE RAW. I think this may be a pretty far reaching rule, actually, since Aboleths and similar underwater creatures will have severe problems (they have ranged powers, and you might speculate that control of their "servitors" requires LoE). Underwater adventuring will also be problematic. The rule about firee attacks getting -2 "if used underwater" (presumably against targets that are underwater, but that's not how it's worded) is indeed in the Rules Compendium, but will be mostly irrelevant if water blocks LoE. Even area bursts need an LoE, albeit to the target point (and the power user needs LoE to the target point), so fireball simply won't work on creatures in water. The target point must be above the water (as otherwise there is no LoE to it) and the burst won't affect under the water (as there's no LoE from the target point to the targets under the water). Seems like a rather problematic rule, to me, but if it works for your group you'll just have to work out the implications as you go, I suppose. Edit: on the original wall question: - the wizard must choose a square of a wall to be the "origin square"; this becomes one "block" in the wall. - The wall is then built out from this origin square with each 'block' of wall having to share a complete side (not just a corner) with at least one but no more than 2 horizontally adjacent wall 'blocks'. - Blocks may be stacked above or below the 'origin layer' up to the maximum height of the wall (or until all 'blocks' are used up, depending on the wall type), BUT... - ALL of the blocks in the wall must have LoE to the original "origin square" of the wall. This is a blanket condition for ALL area effects. The last, critical requirement means that, IF you say that water blocks LoE, walls may never be created underwater. The caster needs LoE to the origin square (so it cannot be underwater) and LoE from the origin square to each square of the wall (so none of them may be underwater, either). [/QUOTE]
