Spell tactics involve experimenting with all 100+ spells that are available in BG2 and are much fun than fighter tactics.
Generally I often read "spell buff" before any encounter that have no save modifiers or challenging scenario that needs proper strategy.

It would help to discuss a basic understanding from veteran players and others for the following

1. Most essential spells useful for "spell-buffing" and in general combat too.
2. Spells that help boost resistances in the game. e.x. Spells protecting Fighters against Golems to take the hard damage rolls and saving throws, etc.
3. Spells that help quick debuff of enemy protection and disrupt their spell-casting
4. Helpful items for Mages - Priest for different scenarios. e.x. Robe of Vecna for quick spell casting and,
5. Any other spell tactics you have to share

These will be very useful for beginners and those to discover new possibilities.
