I have obtained a Ring of Force and need to know the dimensions of the wall of force it creates or:
1) If I am attacked by three ghosts adjacent to each other in front of me do I assume it protects from all three natural attacks and
2) if one of the attackers is a small size, the next a medium, and the third 5ft behind them with reach would I still assume protection from all three?
Ring description:
Description
This ring generates a shield-sized (and shield-shaped) wall of force that stays with the ring and can be wielded by the wearer as if it were a heavy shield (+2 AC). This special creation has no armor check penalty or arcane spell failure chance since it is weightless and encumbrance-free. It can be activated and deactivated at will as a free action.
Wall of Force
description that pertains to question:
Breath weapons and spells cannot pass through a wall of force in either direction, although dimension door, teleport, and similar effects can bypass the barrier. It blocks ethereal creatures as well as material ones (though ethereal creatures can usually circumvent the wall by going around it, through material floors and ceilings). Gaze attacks can operate through a wall of force.
The caster can form the wall into a flat, vertical plane whose area is up to one 10-foot square per level. The wall must be continuous and unbroken when formed. If its surface is broken by any object or creature, the spell fails.
It gives 2 shield bonus to ac. No more no less.
You're way over thinking it.
You could be against a million enemies or 1. The ring still gives 2 ac.
The question isn't applied to the AC bonus, but the wall of force that it creates.
It says the wall of force is shield sized and shaped and functions as any other large wooden shield aside from being weightless, encumbrance free, and not having a spell failure chance. Since it doesn't interfere with your actions at all so it should be assumed not to hamper movement in any way. I'd assume it's about a 3 foot diameter, for a medium user, if it matters.
For all your questions, yes, it works as would any other large shield in that situation. The shield should be larger or smaller based on the shield's user, since it says large wooden shield without giving a creature size. A heavy wooden shield has 15 hit points, meaning it's an inch and a half thick, so your force shield is an inch and a half thick. The shield creates a wall of force, so its hit points are 20*CL, so 180hp and 30 hardness.
The ring of force acts as a heavy shield in all and its bonus applies to all attacks targeting you. The only difference between it and a regular shield is that the AC bonus also applies to incorporeal creatures, which other most other shields do not. It also has no ACP or arcane spell failure.
The description states that it is the same shape and size as a shield. Since it is gives the same bonus to AC and can be wielded as a heavy shield it can be assumed that its dimensions are those of a heavy shield.
Yeah, you're reading into it too much.
It's not a wall of force. It's a ring that creates a magical heavy shield that blocks incorporeal things (like a force effect normally does).
For understanding how it functions it works just like a heavy shield except it can block incorporeal stuff. Technically it has higher hp and hardness being made of force, but that usually doesn't come up, and you can simply reactivate the ring if the shield were destroyed.
