INVINCIBLE SPIRIT, the sire of this year's top milers Kingman and Charm Spirit, will stand for €100,000 at the Irish National Stud in 2015, up from €70,000.
The son of Green Desert has become a leading source of sprinter/milers in his 12 seasons at stud, and in addition to this year's stellar pair - who between them won seven Group 1 races - has enjoyed many high-profile successes through his daughters, including Fleeting Spirit, Hooray and Moonlight Cloud.
Invincible Spirit is also carving out a name for himself as a sire of sires. His son I Am Invincible is the reigning champion first-season sire in Australia, while Tally-Ho resident Zebedee is a leading freshman in Britain and Ireland. Lawman, another son, sired last year's Irish 1,000 Guineas winner and Breeders' Cup Filly & Mare Turf hope Just The Judge. Born To Sea , Mayson, Swiss Spirit and Vale Of York also bolster his numbers at stud.
Kingman will stand at Juddmonte's Banstead Manor next season, while Charm Spirit will join the Tweenhills roster for fee of £25,000.
Irish National Stud chief executive John Osborne yesterday said it was an exciting time in the stallion's career.
"Kingman was a dominant force this season, and he had an able deputy in Charm Spirit," said Osborne. "Between them they mopped up seven of the top Group 1 mile races this season, but even more pleasing was the success of I Am Invincible.
"Invincible Spirit didn't produce many foals in Australia during his few visits down there, and his one shot at being a sire of sires in the country has produced a champion, so that's another massive feather in his cap.
"It's a really exciting phase in his career, and it's ironic to think that a few years ago people thought his fillies were better than his colts, who are now so sought after."
Big Bad Bob is the only other sire on the roster to have his fee increased. He will be available for €9,000 next season, up from €6,000 in 2014.
The stud welcomes two new stallions to its roster next year. Gale Force Ten, winner of the Jersey Stakes at Royal Ascot last year following a second to Magician in the Irish 2,000 Guineas, has been introduced at a fee of €5,000.
Palavicini, winner of the Group 3 Strensall Stakes, will join his half-brother Elusive Pimpernel on the roster. By Giant's Causeway, he was bred and raced by Cristina Patino, whose colours were also carried by Big Bad Bob - a relative of the latest addition.
"Palavicini has been staying with us, and Ms Patino was keen to include him in the market," said Osborne. "He has plenty to offer on his own merits. He was a good racehorse by a sire of sires and the family keeps producing. Elusive Pimpernel was also very popular in his first year with us."
Palavicini's stud fee will be available on application.
The remaining five stallions on the roster will stand for unchanged fees. Globetrotter Worthadd and Dragon Pulse, whose first foals are available at the upcoming sales, will both be available at €6,000.
Lord Shanakill, whose first yearlings sold for a high of 100,000gns, will stand for €5,000, and tough, top-flight campaigner Famous Name will stand his third season for €4,000.
Elusive Pimpernel, who relocated from Islanmore Stud to the Irish National Stud for 2014, will remain at €1,000.
Not included in the 2014 roster is second-season sire Art Connoisseur, who holds an entry in the Tattersalls December Breeding Stock Sale on Monday, December 1.
