If opponents would have weaker weapons it would mean that they haven't traveled a lot, nor they vanquished terrible opponents, which would mean that they should be weaker that they are.
That's is untrue in
BG2 as I can walk into nearly any store and buy a powerful magical weapon. No traveling, no vaquishing and no terrible opponents. Just a price tag. This mod would endeavour to change that.
You are assuming that there are a wealth of magical items scattered about Faerun for adventurers to pick up.
All I am saying is that there aren't necessarily as many magical weapons as there are in
BG2. Shops that sell generic +1,2,3,4 weapons are in every town. The one guy (Cromwell) who can create magical weapons doesn't sell any...Ribald could be believable as a ex-adventurer but the rest...no.
Alot of players like access to high power weaponry, the more the better...this mod would be aimed at those who think access to these weapons is too easy and too frequent.
By reducing the magical enchantment of all weapons, high power weapons become less frequent. The +4 Warblade in Ribalds would now be +2, all the +3 weapons become +1, all the +2 weapons become normal weapons etc.
The weapons would still be there, where they've always been, but not as powerful any more.
