Ring of Sustenance vs. Antimagic Field

[NunoM]

This question came up during a game session while the party was fighting a beholder.

When a character, wearing a Ring of Sustenance, is affected by the Antimagic cone of the beholder, the ring's effects are supressed. Does he have to wait another week to regain the benefits of the ring?

Our DM didn't get much into it (i think he didn't remember this until someone said something ) and just ruled it as "Yes, you felt hungry momentarily during the combat, but you're ok now...".

The ring only needs to be reattuned if it's removed.  An AMF wouldn't remove it, so there's no need to reattune it.

To quote the text at http://www.d20srd.org/srd/magicItems/rings.htm#sustenance

The ring must be worn for a full week before it begins to work. If it is removed, the owner must wear it for another week to reattune it to himself.

Another way to look at it is that you don't need to re-apply a permenant spell effect on you.  By putting the ring on you "cast" the sustenance effect on yourself, just as you might cast a permenant true seeing on yourself.  In the AMF, it is suppressed but it will return immediately after stepping out of the AMF without needing to do any action to re-apply it again.

Jackinthegreen: That same reasoning was presented by me (defending my character) during the session

SolEiJi: Never thought of it that way, but it works as well. Thanks.
