A man who poured petrol over a fellow lodger and set him alight causing life-threatening and permanent injuries has been jailed for 10 years.
Stephen Welsh's attack on Jim Tudor had a "devastating" effect on the 63-year-old, Caernarfon Crown Court heard.
Mr Tudor, who was asleep at the house in Coedpoeth, near Wrexham, suffered nightmares and had extensive scars.
Welsh, 34, of Longsight, Manchester, was convicted by a jury of inflicting grievous bodily harm with intent.
The attack took place early on New Year's Day at a house where Mr Tudor was a lodger with Welsh and his girlfriend.
Welsh blamed her but the jury rejected his story.
The jury was told Mr Tudor had burns to between 40 and 75% of his body and required skin grafts.
He had discharged himself from hospital in April against medical advice.
In a victim impact statement how described how he suffered pain, had nightmares, and was unable to look at himself because of the scars.
Mr Tudor told the jury he had been asleep and then felt something cold on him.
He was there was then a "whoosh" and added: "I went up in flames. I was hot, very hot."
Judge Merfyn Hughes QC said they had drunk large amounts of alcohol.
"At some point during the evening, while Mr Tudor was sitting on a settee, you left the room in order to obtain a saucepan of petrol which you had taken from a motorbike in the kitchen," he said.
"When you realised the seriousness of what you had done you did attempt to put out the fire but by then it was too late."
Speaking after the sentencing Det Insp Dave Spencer of North Wales Police said officers had worked closely with the fire service to "gather the evidence to bring this successful prosecution."
