Immunity to damage in PF

[flappeercraft]

Is there any way to get immunity to damage in PF? Preferably something possible by 10th level and how would you get that in a barbarian?

[gartius]

whilst not immunity to damage you can gain a very high dr from dragon totem resilience as well as invulnerable rager

eg
Unbreakable Fighter 1 / Invulnerable Rager Barbarian X
F1 Combat reflexes, Power attack, Diehard, Endurance
B2 Combat expertise, Reckless abandon // DR 1/-
B4 Stalwart, Intimidating glare // DR 4/-
B6 Animal fury, Extra rage power (Dragon totem) // DR 5/-, Fire resist 1
B8 Vital strike*, Dragon totem resilience // DR 11/-, Fire resist 16
B10 Improved stalwart, Dragon totem wings // DR 17/-, Fire resist 22
B12 Raging brutality, Increased DR, // DR 21/-, Fire resist 26
B14 Improved vital strike*, Increased DR // DR 23/-, Fire resist 30
B16 Greater vital strike*, Increased DR // DR 27/-, Fire resist 34
B18 Extra rage, Mighty Swing DR 29/-, Fire resist 38
B19 DR 31/-, Fire resist 38
