Seeing with a magical eye, you sense a portal. Studying it, knowledge about the portal comes into your mind as though it was a memory you could not recall until now.

You can tell wether an area contains a magical portal or the effect of a gate spell. If you study an area for 1 round, you know the sizes and locations of any such portals in the area. Once you find a portal, you can study it. (If you find more than one portal, you can study only one at a time.)

Each round you study a portal, you can discover one property of the portal, in this order:

  • Any key or command word needed to activate the portal.
  • Any special circumstances governing the portal's use (such as specific times when it can be activated).
  • Wether the portal is one-way or two-way.
  • A glimpse of the area where the portal leads. You can look at the area where the portal leads for 1 round; the range of your vision is the spell's range. Analyze portal does not allow other divination spells or spell-like abilities to extend through the portal. For example, you cannot use detect magic or detect evil to study the area where the portal leads while viewing the area with analyze portal.

For each property, you attempt a caster level check (1d20 + caster level) against DC 17. If you fail, you can try again in the next round.
