Hero Changes
More heroes got an Aghanim buff this time around, namely Beastmaster and Meepo. Beastmaster gets an increased cast range as well as a massively reduced cooldown with Aghanim. Meepo's buff is more or less an open secret gaining an extra clone.
Another hero that got a major buff is Faceless Void. His utli now reveals invisible units and it gets a reduced cooldown with Aganim on. Time Walk gets a buff as well now slowing enemies along the jump direction.
Treant Protector once again got another rework. All his skills got changed. Living Armor now acts as an Aura instead of single cast. Forest Sentinel was removed and a new slow disable added instead.
Terrorblade got a nice rework as well. Metamorphisis conjures illusions as well as changing to range mode. Conjure image got swapped with zeal, a attack speed and regen skill. Reflection replaces Soul Steal, it now conjures images of enemy heroes and damages them.
Finally a new hero is added to the mix, Rubick, an intelligence Sentinel heroes that has the telepathy theme to it. His ulti allows him to steal the last skill that the target hero uses.
Item Changes
With hero changes come item changes as well. Jango can now refresh its charges by buying its recipe at shop. Bloodstone may see a return to the scene now that it gives five charges once assembled. An interesting change is to Hand of Midas which gives a constant amount of gold as well as reliable gold. Its manacost has been removed as well.
Maim is no longer an orb effect for both Sange and its upgrade Sange & Yasha. Desolator's corruption now works on buildings just like Assault Curiass. Towers will come down faster than normal with those two items on your team. A new item is added that reduces magic resistance for heroes in a fixed AoE.
