The Opaline Bubbletear is a Crystal Tear in Elden Ring that can be mixed in the Flask of Wondrous Physick to grant Tarnished a temporary «bubble,» providing significant damage negation for a single attack. This shield increases all damage negation stats by 90% and lasts for three minutes until its user has been struck with an enemy attack or weapon ability in Elden Ring. One way to describe the Opaline Bubbletear would be to compare it with the Tears of Denial Miracle Spell in Dark Souls 3. However, instead of negating damage to avoid dying from a final blow, the Opaline Bubbletear reverses the function by granting Tarnished a chance to survive a powerful attack that would have otherwise critically diminished or one-shot their HP pool.
Referred to by some as the «Get-Out-of-Death-Free Card,» the Opaline Bubbletear grants Tarnished an opportunity to tank a lethal blow that perhaps do not know how to counter or dodge-roll from. It's highly effective against heavy-hitting bosses that begin the second phase of their fight with high-damage abilities. However, Tarnished are recommended not to use this Physick mix while fighting elite enemies with fast attack speed or multiple mobs.
