The DM gave us our statsa for the chars.
We have 18,16,16,14,14,10
So the 18,16,16 will be distributed to strength,con and wisdom.
The 14 can go into dex and then at 4th level the +1 stat can be put into dex to bring that to 15 which is whats needed for two weapon fighting.
If we base things off say a level 9 cleric which will be cleric 4,ordained champion 5.
Attack:
Base Attack: +8
Strength (16): +3
Weapon focus Flail from the war domain: +1
Two weapon fighting -2
Total attack bonus : +10
Damage:
Main hand:
D8 + 3
Offhand:
D6 + 3
Now factor in the reserve feat:
At this stage i will have access to level 4th level spells because of the two caster level drops. So this will give me an additional +4 to damage on each attack.
So the damage from each attack will be +7 now.
Of couse i didnt factor in any stat items, magic weapons or anything.
Usine the same setup:
A greatsword for example:
Attack:
Base attack +8
Strength (16) +3
Total attack bonus : +11
Damage:
2D6 + 4
So it either 2D6+4 or D8+7, D6+7
While the top end damage comes off better with the 2 hander, you will do only slightly less damage with the dual weild but you will also get more swings which brings the damage above the 2 hander (provided you hit with the extra swings).
With spells like magic weapon/greater magic weapon. The difference between dual weild and a 2 hander will widen more since you can enchant both weapons with dual weild.
Sorry if that was all a bit long or over the top! lol
Im just posting it rather than working it out on paper so you can see it and agree/dis-agree or just give your thoughts in general on it.
