Flare of Fortitude

Abilities that trigger whenever damage is dealt to you will still trigger because that damage is still dealt, even though your life total doesn't change as a result.

If an effect would cause you to exchange life totals with another player, the exchange won't happen. Neither player's life total changes.

If a cost would include causing you to gain life, that cost can't be paid. Similarly, you can't pay a cost that includes the payment of any amount of life other than 0 life. However, you can choose to be dealt damage, even though that damage won't result in your life total changing.
