No ability based saving throw bonues were implemented except for the CON-based shorty bonuses.

Wisdom SHOULD give you specific Enchantment spell immunities and a bonus to saves against any mind-altering spells in AD&D 2nd Ed. The saves start at 15, while the immunities start at 19. It's not a generic "buff to resistances" however, only Enchanments, while other spell schools that use the same save die as an Enchanment spell (typically vs. spells) are not affected in the slightest.

Of course, none of this was implemented. Only certain class requirements and the bonus spells are actually in-game. Spell failure, bonus to mind-spell saves and immunities, max casting level, proficiency checks (which were instead clumsily added as extra dialogue choices after meeting a threshold and no roll made, all proficiency checks basically work this way in BG2), or the racial limits on max WIS were all ignored.
