The first part of this video explains how Resist Magic, Resist Fire, Resist Frost, and Resist Shock work in Skyrim. The math is explained, as well as how they stack. Resist stacking can reduce high damage spells into almost no damage at all. The remainder of this video covers ways to improve and cap your resists, including Agent of Mara from 'The Book of Love', Breton racial permanent magic resist, Dunmer and Nord elemental resists, The Lord Stone, Magical Resistance Alteration perks, and Enchanting Resist Magic and elementals.
While it is impossible to cover every build, a few ideas are shown for magic users, shield users, as well as a few generic builds. Your main goal should be maxing Resist Magic, since every spell in the game checks that before the elementals. Some races such as Breton have it much easier than others.
Take the time to plan out what you want to do, even if you are not ready to do it yet. Would it be easier for you to give up the enchant slots, or maybe spending the 5 perks is better? Are you willing to use the Lord Stone, or does your build require something else? Weigh the benefits of what works for you and figure out how to cap your resists without hindering your character in other ways. Keep in mind, elemental resists are applied after magic, so the return on investment for putting them on enchant slots is MUCH lower than magical resist. Maybe you can afford to take a few more damage from spells and put those slots to better use?
Absolutely every character should do 'The Book of Love' quest to get the permanent active effect 'Agent of Mara', which grants 15% resist magic. See my guide here:
