A modified Bard casting table for the BG2 5E Spellcasting mod that adjusts for the un-nerfed, 8th level Bard spell table.
Copy the attached file over 5E_spellcasting\data\5E_casting\d5cstbrd.2da.
The un-nerfed bard table can be obtained from Tweaks Anthology:
./setup-cdtweaks.exe --language 0 --force-install-list 2270
~CDTWEAKS/SETUP-CDTWEAKS.TP2~ #0 #2270 // Alter Bard Spell Progression Table -> Un-nerfed table [Blucher]: v16
The other 2 files below are Paladin and Ranger tables that correspond to vanilla spell progression.
