Dota 2 is an evolving game. As new patches come and go, certain heroes fade in and out of relevance owing to the meta changes. Some heroes inevitably become more powerful than others and it looks like that hero in this patch is Medusa. This hero rose from relative obscurity and is now a first-phase ban/pick for any team. She is considered so strong that only three heroes seem to be able to counter her in this current meta.
Medusa’s changes in April 20’s Patch 7.33 make it so her starting Strength is zero. In exchange, her Mana Shield is now passive and absorbs 98 percent of all incoming damage in exchange for absorbing 3.2 damage per point of mana. This number is further increased by 1.3 damage per point of mana once she hits level 25 and selects the appropriate talent, making her extremely tanky and difficult to take down without the appropriate hero counters.
