Warlock change invocations

[mivanc]

So I started to go through the OC with a pure warlock (evil) and enjoying it so far. Much more work than my good character (Druid/Warpriest) since he's not so much of a tank and can't take the same damage.

I just went up to Level 7 but could not change my 3 Least Invocations as I could before. Is there a limit as to how many times one can change his invocations? Is this possibly a bug?

I probably can take console to change my invocation but would rather not? Hopefully at level 8 I will be able to change my least invocations. don't exactly like one of them and would like to switch.

According to nwn2wiki: "Warlocks may swap invocations they already know for others of the same grade (least, lesser, etc.) every time they gain a new invocation."

So, you should be able to change them at level 8.

In addition, I think you can only swap one per level-up. I was trying to reorganize Ammon Jerro's invocations and could only swap one out.

On the theme of Warlocks, anyone know if the new MotB feat Weapon focus : Ranged Touch Attack helps the warlock any?

I'm tempted to use givefeat on my level 17 warlock to see if it helps, but wondering if anyone made use of it.
