How do I make counterspelling more efficient for a 3.5 Warlock? I've looked over a few caster builds for counterspelling; however not much seems useful/useable for a Warlock.
We are jumping into the game at level 12. There is no multiclass XP penalty; however, there is a 3 class cap imposed on Multiclassing. Also there will more than likely be no LA buyoff; therefore races and templates with even just a +1 LA would be a tough hit. Most published material is okay (including third party, 3.0, Pathfinder, Dragon Mag, etc). Homebrew would even be okay with the DM, but I would prefer to stay away from homebrew personally.
I am going a full Charisma build focusing on social skills and battlefield control. I also plan on taking a 1 lvl dip in the Mindbender PrC to get telepathy and Mindsight access to help us get the drop on most opponents before the battle even begins.
I'll be taking one of the dispelling lesser invocations (more than likely Voracious Dispelling). Having an at will Dispel Magic is great, but I am not sure how to maximize the success chance -- it has a cap of +10 to add to the roll (later on +20 the Caster's Lament invocation). I want to make sure my CL is at least as high as the cap.
Is there any other way to improve the success rate beyond that? Is there anything that would let me take a 10 on a dispel check, or a +X bonus on dispel checks?
It seems like the only metamagic imitating feat that has any real effect on the dispelling invocations would be Quicken SLA; however casting them as a swift or free action 3 times/day doesn't seem worth the feat to me.
The only real bonus that I have found for a Warlock to take for counterspelling (besides just having a plethora of scrolls on hand) is to dip in Cleric or Ur-Priest, take Practiced Spellcaster, and then take Divine Defiance. This grants a way to counterspell as an immediate action during my opponent's turn, to try to prevent anything that would be an instantaneous effect, especially to counter an opponent's Dispel Magic spell.
The only problem with the Divine Defiant route is, that without going an Eldritch Disciple build, that's a pretty big hit to my Warlock CL. And while it may be easy enough to raise my effective CL, any hit that slows my Invocations Known progression is HUGE. If there is another route to gain immediate action counterspelling that would be great.
If push comes to shove, I can homebrew a feat or two (something like "Instantaneous Spell-like ability" that improves Quicken SLA to an immediate action), but I only want to use that as a last resort. Another option for this particular situation might be just to convince my DM to let my casting go off of the Pathfinder Spell Duel rules.
I just found a Pathfinder feat called Dispel Mastery which I will take.
How to get bonuses to Dispel Magic and Greater Dispel Magic?
How to use my dispelling invocations as an immediate action?
Besides carrying level 9 scrolls from all 8 schools and taking Improved Counterspell, what are other ways for my Warlock to counterspell effectively?
Is there a way to cast scrolls as an immediate action(Such as a feat that would let you do it on scrolls that were made quickened)?
-Just about any published material is okay.
-Homebrew will only be considered as a last resort option.
-Races/Templates are fine, but no LA buyoff
-3 Class max if multiclassing.
