When the last big patch of the year, 6.86 was released a couple of reworked heroes were removed from Captain's Mode because of their substantial changes. Last night Valve brought them back leaving only Rikimaru on the sidelines.
Lone Druid, Winter Wyvern, Doom, Faceless Void and Death Prophet have all been reworked and from now on we will get to see new abilities coming out from them:
Lone Druid lost his Synergy to Savage Roar, an active ability that causes enemies in a 325 AoE around him and his bear to run away with 20% movement speed bonus for 1.2/1.6/2/2.4 seconds towards their fountain. An entangled hero will not be able to move still. Spirit Bear also has this ability, but the cooldown is shared with the hero.
Winter Wyvern got her ultimate totally reworked and now the Cursed target is immune from all damage from his enemies but the ultimate duration is now increased and the heroes attacking their own teammate are having extra attack speed.
Doom’s Level Death was replaced with a new passive ability named Infernal Blade,which is an auto attack modifier that applies a ministun for 0.3 seconds and a four second burn that deals 40 + 1.25/2.5/3.75/5% Max HP as magic damage.
Faceless Void lost probably one of the most famous RNG ability in DotA, Backtrack, to Time Dilatation, a spell that applies a debuff to all nearby enemies (650 AoE) for 6/7/8/9 seconds. Causes time to be frozen on all enemy abilities, stopping their cooldowns from making any progress while they have this debuff. It also slows movement and attack speed by 4/6/8/10% for each locked ability.
Worth to mention that Timewalk no longer slows units and has the ranged reduced from 700/900/1100/1300 to 550.
Death Prophet’s scaling based on her Witchcraft passive ability came to an end in 6.86 and now she has a new active spell. Spirit Siphon creates a spirit link between DP and her target that lasts for four seconds draining 20 + 1/1.8/2.6/3.4% Max HP per second and slowing movement speed by 6/10/14/18%.
