You won't run into any Fire-elemental attacks until you reach Mt. Gulg, with the possible exceptions of Fire2 Spells cast late in the battles against Astos or Lich, but when you do get there you'll be very happy you have NulFire. Resistance not only halves damage, but basically ensures the Spell or Special Attack will miss, dealing only a quarter of its maximum damage overall. And NulFire grants resistance to the entire party with a single casting. A great Spell.

The Nul Spells are all quite good, effectively decreasing damage from a given Element by a half to three-quarters, and NulBolt is no exception. However, this Spell isn't urgently needed because you're not liable to be hit with Lightning damage for quite some time. Astos could get around to casting Bolt2 if the battle wears on long enough, as can Lich, but the first time you're actually likely to get hit by it isn't until the Ice Cavern. So feel free to save some money and wait on this Spell, but don't forget it. At least, not until everyone in the party has gear granting them resistance to Lightning anyway.

The only level 4 white magic Spell that is unquestionably good, NulIce is hardly a Spell you ever want to call the best of its level. It's great against White Dragons and Winter Wolves in the Ice Cavern, and is useful to use against Lich since his first Spell will always be Ice2. Those uses are important, but beyond that you're not likely to be casting NulIce much.

NulMgc purportedly grants resistance to KO Spells, but this description isn't entirely accurate. It does give Death elemental resistance, as well as Earth and Status resistance, but does nothing to stop the Time- or Poison-elemental KO Spells you will run into late in the game. Still, it's the only way to gain resistance to Earth or Status short of a Ribbon or the NulAll Spell, which can be nice. It's of limited use once you've found all three Ribbons, though. It is one of the two level 7 Spells Red Wizards can learn, though, so at least for them it's a no-brainer.

NulAll is one of those Spells that sounds far better in description than it is in practice. Sure, it grants resistance to all eight Elements, but so do Ribbons, and you get three of those. Assuming you use them, this Spell can only enhance defense one party member, who may very well be a Knight that already resists the main attack Elements and Poison anyway. On the upside, at least being a single-target Spell doesn't make it any less useful in this case.

Prior to Gurgu Volcano, you will encounter Fire-elemental attacks in the form of FIR2 Spells cast by ASTOS and LICH, and FIR3 Spells cast by MAGES in the Ice Cave. In these cases and later, AFIR will reduce the damage of many dangerous Fire attacks by as much as 3/4.

Due to a bug, AFIR will also protect you against the Status Ailments caused by the attacks of Fire-vulnerable Monsters; this includes many Undead. Of course, you're usually better off using that Spell slot to cast HRM2 or FIR2 instead.
