Anything that will increase your ranged attack accuracy, so long as it isn't a weapon enhancement typically, will work for EB. From the sound of it you don't want homebrew, in which case I honestly do not know of much that will help you other than some standard tricks.
First, EB is a touch attack, so it ignores most armor bonuses and such. Right there you have some darn good accuracy for most things. If you attack from invisibility then you get a +2 on attacks and the enemy is typically flat-footed against the attack, which means lower AC.
Ya for the most part homebrew is out. Minor tweaks might be doable..
Yes I know touch attack is DC to hit is nice and low for the most part, against most monsters should be easy but then add in other races and classes with feats and such that get to add other factors to AC, such as spells, and keeping dex bonus to Touch AC....
Mid to High level it might be possible to play peak-a-boo with creatures every other turn but just like all the focus on hide someone else suggested I just see it as extremely impractical. I just do not want to have to try to nickel and dime lots of little boosts. I want something more constant, but you did remind me I think I did see something somewhere that did work to boost ray spells, so will have to try to find that and see if it could work for EB.
How much of that guide I linked did you read?
HA!!!! Your funny. I read it, 4 other guides, some that say contradictory things (like useing a soulmeld to counter con dmg instead of binder or useing binder feat instead of takeing level), several sections in too many books about other classes suggested and prestige classes, feats, invocations.... Its all a lovely mixed up jumble of info in my head. I am sorry if your really Thinblade and your insulted I do not know your guide by heart.
As I have said never played Warlock before and with guides saying different things its even more confusing. One of the first things I said was I had planed to get Rapid Shot because one of the guides said it could be used with EB, then next post someone said it can't. Guides are nice but they can be wrong and offten others think up new or better ways to do things and do not happen to write out a whole guide to tell people about it.
I prefer to get my info from people who play the class vs a compilation of all data. As I have also said, I do not want to regret how I set up my warlock after afew levels because what looked like good options to me turned out to be wasted effort that I am now stuck with. It can be really easy to look at guides data and pick things that seem perfect only to not work the way you intended or become obsolete after a few levels or to find out you could of done the same thing with a low cost magic item. More so with feats where you end up being denied many paths because you didn't know about a feat that it is required to be taken at first level.
So thank you for suggesting the guide. I had it bookmarked it before I had made my first post when I had searched for info. I am more interested in practical applications people have used with warlocks they have ran.
That was fixed in the CA errata. EB is always a level 1 ability, but essences and shapes upgrade it to their levels.
NICE! thx Redwarlock
