What happens when my Dota Plus subscription ends?

Solution 1:

Actualy there is no statement of Valve about this situation. I will edit my answer as soon as i know more.

Most probably your Progress on the Hero is frozen.

You will be able to:

  • use unlocked chat-wheel phrases
  • spend shards
  • use relics you already have
  • continue progressing after renewing the subscription

You will not be able to:

  • use the plus ingame features (pick/lane/item-suggestions, etc.)
  • complete quests
  • earn new shards in any other way (except getting +400 for double randomed relics)
  • make any hero level progress
