This should (hopefully) be the last thread concerning my character plan I've been working on. I'd like to ask: What's the best way to overcome crit immunity, which often defeats Sneak Attack damage, precision-based damage, crits, and more? Do I need the construct/undead specific spells, or should I be using something else? (I'm planning on making a character that can deal 1.5xDEX modifier damage with crossbows and dual-wields said crossbows for a total of 3.0 DEX modifier damage in a round, but this damage may be reduced/ignored by crit immunity.)
For Constructs and Undead the option essentially comes down to 'Weapon Augment Crystals' which can be found in the Magic Item Compendium. There can only be one crystal in any one weapon, but they let you overcome the constructs' or undead's immunity to sneak attack and crits. There are also feats that let you sneak attack undead, but I'm not sure what book they're in.
Augment Crystals is your best bet. Just swap them out as needed.

You may have been referring to that rogue alternate class feature from 'expedition to castle ravenloft' or similar source.

I'm going to take note of those crystals, then. I have another question.
A lot of things that allow you to Sneak Attack undead/whatever have a disnomer that says "Hey, you can use this for sneak attack, but it doesn't make the creature vulnerable to crits and stuff." In other words, precision based damage doesn't work with these abilities, which a lot of the things I'm interested in technically are. Is there a way around that, too? Would the Augment Crystals allow that?
I'm pretty sure that the Augment Crystals (the greater versions) say that they make them able to be crit, sneak attacked, etc. I'm not sure if you could infer that would allow other precision type damages or not. The crystals also do extra damage to their respective counter as well I believe.. anyway. Check them out :3
Would the Augment Crystals allow that?
RAW no…you should request this and it will probably pass. I'm pretty sure nobody is using sneak attack/precision frequently enough to have noticed.
