Bonus Mana Regen decreased from +1.4 to +1.25
Soul Release charge gain radius increased from 1400 to 1500
Soul Release charges can now be gained by all copies of Urn of Shadows item
This change is exclusive to Urn of Shadows and doesn't affect Spirit Vessel
Soul Release charges can now be gained by both Urn of Shadows and Spirit Vessel from the same hero death
Example to show the result of these two changes:
Two allied heroes. Both of them have both Urn of Shadows and Spirit Vessel. An enemy hero dies within 1500 range from them. Both Urns of Shadows will gain a charge. Spirit Vessel will also gain a charge as well, but only for the ally that was closer to the dying enemy
