Ghost Mask clarification

[Falkyron]

Hello everybody. My group has encountered some disagreement in regards to how the Ghost Mask functions.

Player A reads as follows:

Ghost Mask description wrote:

Additionally, the wearer is treated as one size category larger and gains a +4 bonus on all saving throws made to resist the effects of wind.

This player believes that the Ghost Mask allows a character to gain benefits similar to Enlarge Person, but without taking up 4 squares of space. The argument is made that the 'and' in this item's description makes the effect 'treated as one size category larger' stand-alone. The character's example of making use of this was using bull rush on larger creatures with a higher bonus.

Player B reads as follows:

Ghost Mask description wrote:

Additionally, the wearer is treated as one size category larger and gains a +4 bonus on all saving throws made to resist the effects of wind.

This player reads the benefits as if they apply to wind effects entirely, stating that it would allow the character to resist wind effects from spells and weather far more easily. The player notes several examples in previous character options where the intention of such an ability is stated to support his interpretation, as well as the theme of the item and balance issues if it didn't function this way. The player also mentions several effects it would affect significantly, such as Gust of Wind or an air elemental's whirlwind ability.

We are searching for neutral opinions to resolve this matter. Assistance would be appreciated.

Player B is definitely correct. The main ability of the mask is to see through fog and silt. An increased resistance to wind effects is the additional benefit.

Player B is correct.

You do not actually increase in size or gain any benefits of being enlarged except for in the context of resisting effects of wind.

[John Murdock]

player B is the correct one

it never you say you become larger but you are treated as larger instead and the resistance to wind effect is an additional bonus.

so take whirlwind from an air elemental, it can take creature one category smaller, it is large you are treated as larger it cannot engulf you into its whirlwind now simple as that

I will link this post to the players now. Any further insight would still be appreciated, and I thank you for your opinions thus far.

I concur with the above. Treated as means you don't increase in size, you are just treated as being larger for some purpose. To resist the effects of wind tells you the purpose for which you are treated as one size larger.
