Ring of Counterspells Trigger action?

[Stephen Ede]

Does a Ring of CounterSpells trigger on been targeted with a successfully cast spell, or on the spell affecting you?

i.e. If someone cast a Slow spell on you (and your Ring has Slow stored) do you
1) Make a Save and if successful the nothing happens, but if fails the Ring then Dispells the Slow.
or
2) The Ring Dispells the Slow and no Save is made?

The basic Text talks about been cast upon the wearer, which could be interpreted as before or after the Save (English is such a wonderfully imprecise language (headbang))
The FAQ talks about Targeting, but only in reference to non-targeted spells not triggering the Ring at all. Which doesn't really tell you when the Ring triggers.

Thanks

Upon first examination, this ring seems to be a ring of spell storing. However, while it allows a single spell of 1st through 6th level to be cast into it, that spell cannot be cast out of the ring again. Instead, should that spell ever be cast upon the wearer, the spell is immediately countered, as a counterspell action, requiring no action (or even knowledge) on the wearer’s part. Once so used, the spell cast within the ring is gone. A new spell (or the same one as before) may be placed into it again.

Does a ring of counterspells counter area of effect spells such as fireball?

The ring only affects spells that target you, not spells that include you in the area. One possible interpretation is that the ring would make you immune to that casting of the spell (and the rest of the area would be affected normally), but that would require additional explanatory language and create strange situations where you’d be immune to control water or guards and wards and able to wander freely through such effects. Instead, it is clearer to adjudicate if the ring only affects spells targeting you.

Slow affects multiple targets so this raises a lot of questions. I looked into some past threads about the verbage "one creature/level, no two of which can be more than 30 ft. apart" and some interpret it as a circle while some interpret it as a line, but it seems like everyone considers this to be an AoE effect. And Ring of Counterspells does not affect AoE spells.

Don't take my word as 100% right though. I’m curious to see what others have to say about this.

Edit: But to answer your question about how it works, no action from the wearer is required. The ring automatically counters the spell and no check is required. For example, if you placed Hold Person or Remove Paralysis in your Ring of Counterspells and then you got hit with a Hold Person spell, the Hold Person spell would immediately become countered as if you had successfully spellcrafted the spell and countered with your own Hold Person or Remove Paralysis spell per the normal counterspelling rules. You don't have to make any CL checks or Saves or even one of your actions in combat, the ring does it all for you.

(The wording of the magic item may be clarified in future errata.)

You must target someone to affect him with slow. It works.

To reply to the original question:
it is an automatic action done by the ring, before you roll the save.

Does the ring have a spell stored in it, and is someone casting that spell targeting you?

Yes: The spell is countered. The ring is now empty.

No: Proceed as normal.

It really is that simple.
