I think the MWM damage is added to character and is not subject to resistance. Dropping FS to 25 and raising Fighter to 13 for +6 str is also an option.
The builds are slightly different (the one I put up has only 10 dex and hence no Expert Tactician, but has 16 int, 14 Con, and Imp Expertise built-in for example), but I agree that the general analysis is valid even if they were built with the same starting stats.
The main advantage of the hybrid build is that it's less melty when hit by dispels and can still fight decently (Mid-80s AB) when short term buffs wear out.
Of course, it does lose out to the pure FS when picking up DM items, and "enjoys" as whooping 60% XP penalty though
Small side note: The original build would need to switch deity to Finder Wyvernspur as Kelemvor is not compatible with a CG Cleric alignment.
How about this?http://nwn2db.com/build/?261526
Loses: 10 EDM damage, duration, and DCs.
Access to barbarian gear
Gains: +4 to hit and +2 to damage (Inspire Courage +7 and Battledancer) - (+103 to hit O_O)
Curse Song at 16 Bard song level (Artist counts as +3. Full ER bonuses, -5 AB, -7 AC penalty at ER5 is pretty good)
Retains full 40 FS casterlevels.
