Because the 6th goal of 2.6 million US dollars was reached for The International 2013 fundraising, Valve has released different immortals for players who bought the International compendium.
Each player gets an Immortal Reliquary.
Open the Immortal Reliquary and get a chance to get the following items.
2013 Compendium Immortals:
Leviathan Whale Blade - Kunkka Immortal
Upon the rough seas swam the wondrous and terrible leviathan whale, set upon consuming ship and crew, and when it had eaten its fill did it vanish into the roiling waves leaving stranded those in its wake. Forged by one that lived, the blade ever seeks the heart of the beast.
Cauldron of Xahryx - Lone Druid Immortal
Until at Sylla's paw the vile Xahryx fell asunder, the wildest power known was held within the cauldron's depths. In fear of what evil may seek such strength was the vessel taken, and put to heroic purpose.
Whale Hook - Pudge Immortal
Ideally, a hook made for reeling in enormous creatures of the deep would not gouge and hack into the bones and flesh of the prey. But Pudge doesn't much care if he makes a mess of his meat.
Scree'auk's Talon - Vengeful Spirit Immortal
Scree'auk's Talon was fashioned by a certain winged Mage, forged from shades of unrequited passion, tempered in grief, and quenched in the secret tears of her admirer. More's the pity that she uses it now, approximately half the time, to hunt him.
Mace of the Chosen - Abaddon Immortal
Weapons forged in the primal mists of the Font of Avernus may only be wielded by those the Font has chosen to defend it.
