Spell Penetration 101 + feats/enhancements/gear

[Commodore]

What is Spell Penetration? A Spell Penetration check is made any time a spell is cast on a target that has Spell Resistance. If the spell resistance is higher than the spell penetration then the spell will have no effect and players will see a blue shield appear over the target.

Once spell resistance has been bypassed the target still gets to make their normal save against the spell if there is any.

Spell penetration items have a level qualifier. For example the Epic Torc of Prince Raiyum-de II has Greater Spell Penetration VIII. This means the Epic Torc gives +3 to spell penetration checks to all spells level eight and lower.

Don't forget the Vibrant Purple Ioun Stone can be a reward for every 3rd completion of The Dreaming Dark. Incidentally, you'd need to run that quest if you wanted to unsupress your Stone in order for it to have the Spell Penetration.

When I was farming for mine, I did 2 runs of Dreaming Dark, then on the 3rd run if I didn't get the Ioun Stone I was after, I abandoned the quest and re-took it, which again counted as a 3rd run completion (because I didn't collect a reward and flag the quest as complete on that 3rd run).
