You need 120, because lava gives you the burning debuff, which gives -20 Fire Resistance.

But Fire Shield is 50, and Weather the Storm is 25. That leaves only 45 Fire Resistance you have to get from other items or essences. And it is GOOD to have somebody at 120 Fire Resistance, because then they can walk through all those crazy exploding traps and lava in other areas of the game.
