Banish
From Liquipedia Dota 2 Wiki
Banish renders the target invulnerable and untargetable. However, abilities from the user can still affect those banished. For example, Outworld Devourer's Sanity's Eclipse will affect units banished by his own Astral Imprisonment, and Shadow Demon's Shadow Poison, Soul Catcher, and Demonic Purge all affect units banished by his own Disruption.
Banishes are commonly used to dodge spells, escape death, or prepare for skillshot attacks.
