Greetings all,
People often recommend dualing from fighter to class X at 13th level. I've just turned 12th and am wondering if there's anything special about level 13 that makes it worthwhile hanging out for. There are two reasons I can think of that indicate 13th would be better than 12th, but can't find any supporting info in the docs. These are:
1. In PnP AD&D, getting a new proficiency every 3 levels leads to a progression of 1, 4, 7, 10,
13, ... The way it is coded in the IE, however, it is interpreted as 1, 3, 6, 9,
12, ... Having just turned 12th, I just got a new proficiency and there is none coming at 13th.
2. In 1st Ed. AD&D (the Ed. I'm familiar with), fighter classes gained extra attacks per round based on level. I think the progression was 3/2 attacks at 7th and 2 attacks at 13th. From what I can tell, 2nd Ed. rules remove this and replace it with proficiencies, again leading to no gain at 13th.
So, assuming the two points above are correct (I'm more than willing to be wrong here

), is there another reason for me to press on to 13th? I imagine thac0 will go down another one, I'll gain 3hp and possibly some saves will drop further. Anything else?
Many thanks for any illumination on this black art.
