Most weapons have 1 variant for each enchantment level, but ninja-to and wakizashi offer only a generic +1 and the unique +4 in ToB (Yamato[Saradush merchant], Unsuno's [Watchers Keep])
In BG1 the +1 can only be obtained in Dorn's ambush encounter, so pretty much no variety.
What I would like to have:BG1
+1 (generic + uniques), available in chapter 2+ areas
+2 (uniques), available in chapter 5+ areas BG2
+1 (generic + uniques), available in chapter 1+ areas
+2(generic + uniques), available in chapter 2+ areas
+3 (uniques), available in chapter 4-5+ areas
+4 (uniques), available in chapter 6+7ToB
maybe an upgrade option for the existing to +5
The biggest issue I see with this is keeping the compatibility with other mods. What if I change the inventory of an excisting NPC or container that get altered by mod xyz too ?
Similar issue: Offering an upgrade option (cespenar, dwarf in docks district), adding some dialog and scripts should be fine. But what if an other mod does the same ?
Anyhing to consider to make this compatible with Item Revision ? Naming convention for weapons, installation order, etc ?
Are there (A)D&D books that have a list of potential weapons that could be used, or are their copyright issues with WOTC when those are used?
Any weapons you would like to see?
What do you think, would that be something you'd be interested in?
Maybe there already is a mod that tackles the same issue ?
Balancing issues - that extra gold influx should be negligible if you dont use the new weapons. But the enchantment level and extra features shouldn't surpass vanilla weapons at the given stage of the game.
