Dota 2 just got a major update - patch 7.38, its balance changes are being implemented in Dota Mod.

In 2.3.1 update:

• 1 new item - Orb of Frost:
  • Equipment, costs 250 gold.
  • Works like Eye of Skadi, but significantly weaker.
• Battle Fury:
  • Now requires the second Broadsword to craft instead of Claymore.
  • Recipe cost increased from 450 to 600.
  • Total cost decreased from 4100 to 3900.
  • Attack damage decreased from 20.25 to 16.5.
  • (Bauble) Attack damage bonus decreased from 6.75 to 5.5.
• Eye of Skadi:
  • Now also requires Orb of Frost to craft.
  • Recipe cost decreased from 1300 to 1050 (Total cost unchanged).
  • Cold Attack: effect will not stack with Frost from Orb of Frost and will have higher priority (similar to Orb of Blight and Desolator). Dota 2 does not have this, but I think it is necessary.
  • Cold Attack: enabled effect particles.
• Orb of Blight:
  • Renamed from Blight Stone to Orb of Blight.
  • Lesser Corruption: duration decreased from 6 to 3 seconds.
  • Updated description.
