[QUOTE="Greenfield, post: 6289853, member: 6669384"] Line of Effect is an interesting thing. We normally think of it being stopped by "hard cover" like a foot of stone, an inch of iron or other metal, or a thin plate of lead or gold. We also think of it as the line from the caster to the target. But in the case of burst or emanation type spells, it's also the line from the focal point to items or creatures in the area. So presume a tower shield, which can provide 100% cover (says so right in the description). Presume a tower shield covered in hammered gold, or with a lead foil lining. If you suspect that someone is going to cast a spell like [I]Dispel Magic[/I] or [I]Disjunction[/I], and you ready action, could you (subject to Spot and Spellcraft checks) face your shield in the right direction and crouch down behind it, thus getting 100% hard cover to interrupt the Line of Effect? Bye the way the rules are written, the answer seems to be yes. Some spells, like [I]Fireball[/I] are "spreads" rather than "burst". These wrap around corners. [I]Dispel Magic, Greater Dispel[/I], and [I]Disjunction[/I] are all "burst, so they don't wrap around corners. Somebody please tell me why this doesn't work. Please? [/QUOTE]
