My game uses unchained rules of automatic bonus progression. So the sihedron amulet is just a free action false life, and the sihedron ring does nothing at all.
I still have a lot of months until we go there, but I'm already trying to figure what could the sihedron rings do instead. It should be something universally useful, like the original, not something caster or martisl oriented.
I was thinking about something like a luck stone maybe. Other options include a +2 insight to AC, or saves, or both, or some sort of energy resustance ring (maybe something like resistsnce 15 to the las element that damaged you.
Another option could be to add a free action spell, similar to false life.
Any thoughts?
Ring of ferocious action (3k)
Ring of Mind Shielding (8k)
Ring of Inner Fortitude (18k)
or Ring of Energy Shroud (19.5k)
Ring of Return (33.6k)
Ring of Freedom of Movement (40k)
Those should be in just about the right price ranges, for +1 through +4. +5 is a little iffy, in that the general purpose ones are either a good bit cheaper (FoM at 40k) or a lot more expensive.
The Rings are +3/+3 to resist and AC, they are wirth 35k and the PC find them much later, lvl 14+ I think.
I'm leaning towards maybe +1 Caster Level and Greater False Life 1x day as free action (a better version of the amulet)
Either that, or Spell Storing
I thought you wanted something NOT martial or caster oriented? +1 caster level and a free Greater False Life is VERY caster oriented.
+1 Caster Level is obviously too caster oriented, yes. That's why I'm doubting with Spell Storing (which helps Martials more than casters). Greater False Life as a free action works for anybody, though.
I'd go Freedom of Movement. It's a very nice thing to have always on.
