With the spell Clashing Rocks, it says:
If the clashing rocks miss the target, the target still takes 10d6 points of bludgeoning damage from falling rocks and is knocked prone. A successful Reflex save reduces this damage to half and the target remains standing. Creatures other than the target that occupy the spaces where the clashing rocks appear or within their path (30 feet wide, 30 feet high, and up to 60 feet long) must also make Reflex saves or take 10d6 points of bludgeoning damage and be knocked prone (save for half and remain standing).
I have two questions:
1) For the area it says "up to 60 feet long". Does this mean you can choose to make the area smaller (such as 30 feet wide, 30 feet high, and 5 feet long)?
2) The section about affecting creatures other than the target taking damage appears in the paragraph beginning "If the clashing rocks miss the target..." If you hit on the touch attack, is there any area of effect damage at all?
