But anyhow rambling about my former sex life aside...
Verbatim from Chevy's EM thread:***Here's a list of what's being changed for warlock invocations:-Dark One's Own Luck.Only grants the bonus to one saving throw type (fortitude, reflex, will) at a time as per PnP. If it is recast, the old bonus is removed.-Flee The Scene.Doesn't grant the whole party haste. Grants the caster and those within touch distance (very close) a temporary speed buff.-Chilling Tentacles.For lag purposes, this will be limited to one patch at a time. Casting it twice in a row will cause the first patch to vanish.-Eldritch BlastsAll eldritch blasts that roll a ranged touch attack have the chance to crit for double damage. Also, if they have Point Blank Shot, they will get +1 attack bonus if the target is close.-Hideous BlowThe Hideous Blow blast shape casts like a buff. You cast it on yourself and then run into combat. This is an imperfect fix, so I may change it yet so that it works like a toggle and that every attack until it's untoggled functions as a hideous blow (and will also reduce your number of base attacks to 1 per round until untoggled).Brimstone BlastVitriolic BlastUtterdark Blast-All essences can stack that are supposed to be able to stack. Brimstone blast can be coupled with vitriolic blast. Multiple utterdark blasts will continually add negative levels. Hellrime blast does not stack. The stock invocation code causes any essence to remove all other essence effects applied by the same blast shape.-Word Of Changingfunctions as Baleful Polymorph instead of a useless self-polymorph. Word of Changing is effectively a 5th level spell in PnP, so the DC to resist is relatively low. On DC, the resulting effect is only semi-permanent (can be dispelled or rested off).Name of target changes to reflect the new appearance.-The Dead WalkWill scale with caster level much like other undead summon spells in the game.-Eldritch DoomBlast shape now radiates from the caster and picks targets intelligently. Specifically, allies are never damaged by it and enemies are. In the case of utterdark blast, enemy undead are not hit and friendly undead are.-Retributive Invisibilitylasts 1 round/level.-Dark Foresight.Grants 15/adamantine damage reduction instead of 30/adamantine or 10/cold iron.-Devour Magic.Bonus HP do not stack anymore. Whenever you cast this, old bonus HP are removed.-Tenacious Plague.Attack bonus of the insects is increased to scale with caster level instead of gaining a bonus from charisma. This ability is considered a summon. [Malice edit] Tenacious Plague (and Greater TP) should no longer harm the caster (as supposedly intended)-Wall Of Perilous Flames.Modified to last 1 round/level. Like Chilling Tentacles, only one may be in effect at any time.-Devil's Sight.This should, um, actually work.-Eldritch Chain.Spurious attack rolls removed and other bugs fixed. In short, it will hit more often. With the stock invocation code, this ability misses far more often than it's supposed to.-CharmCharm invocations will not allow you to control multiple creatures.EDIT: A note on Chilling Tentacles and Wall of Perilous Flame. These abilities have been limited to cope with lag, but the number of AoEs a warlock can have in effect may be increased. There will be a limit, though, so that spamming of these abilities is impossible.EDIT2: The first NWN2 expansion is apparently going to add a weapon focus for ranged touch attack, so I'm not going to bother.
