Mod: Icewind Dale's Spell Progression For Baldur's Gate

Hello everyone

I've been looking at Icewind Dale's spell progressions and saw that it would be very interesting to use them on Baldur's gate. So I adapted them to be functional in Baldur's Gate. Not a big deal, but I think it can help a lot of players (especially those who use Jaheira, you'll see why). I also made three cleric and druid spells universal Grades:

The new spells that druids have are only added after leveling up on NPCs.to make the game more balanced.

Changes in some classes:
- Bards: Bards now have spells up to level 8 (obviously at a very high level: 29);
- Paladins and Mateiros: now reach level 6 spells (obviously at a very high level: 29). In Icewind Dale, they get priest spells at level 6, so, to avoid inconsistencies with the class descriptions, I changed them to receive at levels 8 and 9 as usual;
- Druids: I had to use the same level progression that is used in Icewind Dale because they have a huge leap from level 14 to 15 in spell slots. Now the amount of a druid's spells is equal to that of the clerics.
- Wizards: before they only had 2 level 9 spells to cast, now 6;
- Sorceres: i did a small change from level 19 to 20, before you had 4 lvl 9 spells to cast in lvl 19 and 6 in 20, now you got 4 and 5, as all the rest o progression of sorcerer.

NPCs:
Jaheira: with the old progression, Jaheira being multiclass had trouble reaching level 15 of the druid in SoA. That was a shit, since you would need at least 6 million xp to get it. This is no longer a problem now. And with the new spells, she becomes even more useful as a protector.
