For the Swashbuckler:
1. Configurations are located at the top of the script for each spell (below the description, there's a Configurations line marking the start of it)
2. This applies to all four spells
3. UnitDex used by this pack potentially collides with Purification Bombs' Unit Indexer...
Those functions might be replicable with the memory hack @anssik and I suggest you try to look into it. It's not viable in 1.27b and 1.28 patches though. You can try plugging BonusMod to emulate the effect to a good extend.
Please provide links for the problematic ones. That would tremendously help everyone who wishes to help out.
I'm happy my works are of use ^^
Perhaps this can help?
Warcraft 1.31+ does not need third parties.
Usually, systems and spells have configuration codes (uppermost part or a special config trigger in GUI). When you import them, you need to alter the config codes in these portions accordingly.
