How Underlord and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Underlord and Io win 49.73% of ranked matches when playing on the same team, over 2,745 matches.
Pairing Io with Underlord forces a choice between extreme survivability and raw damage output. On one hand, Tether and Overcharge make a naturally tanky Underlord a nightmare to bring down in fights. The bonus movement speed helps him get into position for a good Pit of Malice, and a Relocate gank can put him right on top of the enemy backline to start a fight. On the other hand, Underlord doesn't benefit from the attack speed bonus nearly as much as a true right-click carry would. You end up with a very stable, hard-to-kill duo that excels at controlling space but can lack the immediate kill threat needed to close out games.
