Bastion

When you are a target of an attack, spell or ability from a creature or object that does not wrap around corners (for example, a red dragon's breath weapon or the lightning bolt spell, but not the fireball spell) which forces you to make a Dexterity or Strength saving throw, you can use your reaction to impose your shield between the source of damage and yourself, allowing the following features:

• You cannot be forcibly moved from the attack, even if you fail the saving throw.
• Creatures in a 30-foot cone behind you have 3/4 cover from the effect.
• Creatures in the 30-foot cone also gain evasion for that saving throw in particular.
