So our group has been completely and utterly defeated time and time again when it comes to Will saves because most of our group are fighter types. You've got a warblade, a ranger, a fighter/rogue, a fighter/sorcerer/eldritch knight, a sorcerer, and a favored soul. Add in the fact that two of the characters have legacy weapons that lower your Will save bonus, and most of us has average or low wisdom (the fighter/rogue has WIS 8), and we haven't got a prayer against DC 27 will saves. The worst had to be when we were fighting a legion of archer harpies. So many songs. And potions of deafness, as well as a ring of silence, does nothing against dispel and slashing dispel. Short of taking the feat Iron Will, which would kind of hinder us from getting other feats that we're striving to get, our options don't seem overly high.
We have cloaks/vests of resistance +2 and +3, but what else can we use that'd stack. Periapts of wisdom aren't that common, and most of us have amulets of natural armour +3. My character's probably the only one without anything in his neck slot. I've been looking and looking, and I found an ioun stone, but of course it's not a slotted item, so therefore it's double the price a cloak is.
Is there anything else that we could use that maybe has untyped bonuses, or stack well with one another? Maybe even items that can block enchantments, or protect against such incredibly high DCs?
The DM hasn't been able to find anything for us through his contacts, so I'm hoping someone on here help.
BTW, anyone thinking "It's okay, you don't have to worry about this too much because it won't happen that often" doesn't know my DM, or hasn't read my posts from a few months ago. All enemies that we face, somehow have at least one escape from us (usually teleport or dimension door), and they tell every single possible enemy that we will ever face in the future through some kind of message board memo. You know the type. They say "If you ever go up against these particular people, they're weak against will saves and enchantments, and make sure to use cold items against the red dragon. Also, don't let him flank you unless you want to die. BTW, the half elf and thrikeen almost never miss, and do insane damage. Take them out first."
