7.41f, shipped September 15, 2026, is a broad balance letter patch: roughly 40 heroes and 16 items touched. The through-line is a nerf wave aimed at the 7.41e winners — Treant Protector, Bounty Hunter, Spectre, Lifestealer, Earth Spirit, Shadow Fiend, Lina, Keeper of the Light and Winter Wyvern all lose something — alongside cost hikes on late-game items (Octarine Core, Daedalus, Heart of Tarrasque) and lifesteal trims (Satanic, Mask of Madness). The buff list is short: Anti-Mage, Batrider, Chen, Disruptor, Mars, Ursa and Warlock. Measured win-rate movement lands on this page as post-patch matches accumulate.
