Heroes Changes
Huskar has been hugely buffed now with indefinitely stacking Burning Spears, and Aghanim's that increases damage done to enemy by his ultimate (65% of their HP) and a reduced cooldown from 15 to 8 seconds. Looks like Aghanim's is item of choice on him now.
Razor has been remade to be less of a point-and-click hero. Chain lightning has been replaced by 'Plasma Field' - a huge AoE nuke that hits twice if you micro, and his ultimate is now an active that attacks one unit at random. Just like 'Static Link' does, but presumably his ultimate has been coded to attack the linked enemy in particular.
Medusa now has an AoE Purge for her ultimate 'Stony Gaze' But it only works on enemies that attack her or are facing on her Which means its useless while chasing. Chain Lightning has been replaced by 'Mystic Snake' which just seems to be a slower version of Chain Lightning.
Sniper's scattershot has been replaced by 'Shrapnel' - a 30% AoE slow that does 40 dps over 10 seconds at level 4. Unfortunately such a skill would only slightly boost Sniper's survivability, and the slow only affects units in the AoE to boot. Which means he's still gank fodder.
Also now he can no longer one-hit creep waves, making him more of a sucky farmer.
Aghanim's now reduces his ultimate's casting time and increases range.
Items Changes
New icon for Bottle
Ghost Form is an ability that makes you invulnerable to attacks, makes you unable to attack, but lets you cast spells. Unsure if you take more damage from spells in Ghost Form, or if you're even targetable. Would make it a decrepify clone, except without the movespeed reduction.
Quelling Blade cheap new item that gives +40% damage (20% for ranged) vs. non-hero units. Clearly an item meant to help melee heroes farm. Good starting item for Void.
The Leveller, upgrade for Quelling Blade. Gives a lot of +stats specially for agility. Plus 40% damage to non-hero units and 60% damage to buildings (20% and 30% for ranged) as Demolish skill.
Monkey King Bar now has 'True Strike', a passive that ensures your attacks always hit by passes evasion. Which means it counters the above item.
Manta Style is now an upgrade for Yasha. It has Illussion as active skill, no longer give Feedback orb, and only gives +stats and bonus move and attack speed.
Diffusal Blade is now upgradable like Dagon Level 1 - +22 agi, +6 int, burns 20 mana, Level 2 - +36 agi, +10 int, burns 36 mana. Upgrading the recipe refills Purge charges (8).
Sange and Yasha no longer needs a recipe, so it's 500g cheaper overall.
Reduced Hammer cost by 10
Rapier back to +250 damage
Reduced Radiance Recipe cost
Vanguard now gives 70% block
Maelstrom's Recipe and stats have changed:
Mithril Hammer (1600g) + Gloves of Haste (500g) + Recipe (900g) = Maelstrom (3000g)
Grants +24 damage, +15 attack speed, and a 20% ctc 150 damage Chain Lightning.
Butterfly's Recipe changed:
Eaglehorn (3300g) + Quarterstaff (900g) + Talisman of Evasion (1800g) [No Recipe]
Balanced
Now the items reflect the theme just like Mithril Hammer -> Hammer icon of Maelstrom as well as synergize with the proc (more attack speed = more Chain Lightning procs).New System of messages when one takes a rune.
Completely revamped LR
Courier now has new skill , Return Home
Emphasis to farming , many tool-tips now have " Damage to non-hero units "
Undying's Tombstone AoE dropped a lot (for instance at 4 its 1200->1000).
