How Warlock and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Warlock and Io win 48.84% of ranked matches when playing on the same team, over 2,076 matches.
Setting up for a Relocate play can feel awkward with this pair. Io is looking to amplify a core that deals damage quickly, but Warlock is a slow-casting hero defined by large, area-of-effect spells. While Warlock can drop his Golem after arriving, he doesn't get much value from Overcharge and becomes an easy target once his ultimate is on cooldown. Io is then left tethering a support who can't really leverage the buffs, instead of empowering the team's actual damage dealer. This lack of a clear offensive partnership means their success often depends more on the other heroes in the draft than on any special dynamic between Warlock and Io.
