Worcester will take a nine-point lead into the Championship final second leg against Cornish Pirates at Sixways, having won 21-12 in Penzance last Wednesday.
And if Warriors emerge triumphant, they will also confirm Leeds Carnegie's relegation from the Premiership.
Only a Pirates' aggregate success can save Leeds, with Worcester the sole Championship club to meet minimum Premiership entry criteria.
But Leeds should not give up hope, given the Pirates claimed a narrow league victory on Worcester territory earlier this season.
"There is no talk of the lead," said Worcester head coach Hill. "We are not talking about promotion or the nine points.
"This is about one game, and that is the beauty of winning the first tie. We haven't got to fuss about anything else. The task is now clear, and we have got to win the game.
"It was critical to get the win in the first leg.
"If you are coming back and you have lost by a point or two points then a lot of tactics start going through your head about kicking goals, kicking for corners or drop-goals. You panic about conceding early points.
"The massive task was to go to Cornwall and win because that means here is just a normal game and we have to win.
"There is no pressure on us. We are very cool and very calm about it. I expect us to be ruthless and we want to win and put a performance in.
"We didn't play anything like how we can play as a team last Wednesday. It was an ugly win and we did what we needed to do to win 21-12. We have got a huge amount to come if we really click."
Hill makes one change for the 12,000 sell-out clash, with centre Alex Grove replacing Alex Crockett, who drops to the bench. Prop Adam Black and lock Greg Rawlinson, meanwhile, both feature for the final time in Worcester colours.
Despite the nine-point margin they face trying to close though, the Pirates will head to the West Midlands in upbeat mood.
Pirates high performance manager Chris Stirling said: "This game will inevitably be as intense as it gets, but we have beaten the Warriors at Sixways this season and we would love to do it again.
"We will need to start better than we did at home and not make unfortunate mistakes, and if we can play with a bit of tempo and create chances then who knows what might happen.
"Worcester are a well-organised outfit, as you would expect, but I am proud of what the boys have achieved and we will be looking to end the season on a high."
