It's a bit lame, but if a ring's duration is a few minutes you can just assume that you're re-activating it between encounters. It's not worth the trouble to keep track of the exact time between encounters as you're traipsing through the dungeon.Cheiromancer said:I think rings of invisibility should be use activated, not command activated. Having them "turn off" every few minutes is kinda lame, IMHO.
skeptic said:Okay, I found the answer by myself in the FAQ, the duration is by caster level.

SRD said:To use a magic item, it must be activated, although sometimes activation simply means putting a ring on your finger. Some items, once donned, function constantly.

Use Activated: This type of item simply has to be used in order to activate it. A character has to drink a potion, swing a sword, interpose a shield to deflect a blow in combat, look through a lens, sprinkle dust, wear a ring, or don a hat. Use activation is generally straightforward and self-explanatory.
Many use-activated items are objects that a character wears. Continually functioning items are practically always items that one wears. A few must simply be in the character’s possession (on his person). However, some items made for wearing must still be activated. Although this activation sometimes requires a command word (see above), usually it means mentally willing the activation to happen.
SRD said:Activation: Usually, a ring’s ability is activated by a command word (a standard action that does not provoke attacks of opportunity) or it works continually. Some rings have exceptional activation methods, according to their descriptions.
SRD said:Invisibility: By activating this simple silver ring, the wearer can benefit from invisibility, as the spell.
