Damage reduction

Had this happen once night, I was playing Legacy and had Fortitude out. Later Tempest played Shielding Winds. On the Environment turn the Enraged T-Rex was played, targeting me for 5 damage. Since Fortitude was out first would it reduce it to 4 and thus not allow Shielding Winds to prevent any?

Fortitude - Reduce damage dealt to Legacy by 1.

Shielding Winds - Whenever a Hero would be dealt 5 or more damage from a single source, reduce that damage by 2.

Another thing that happened was Fanatic then played Undaunted. If Fanatic is targeted for 5 damage would both cards effects go off or would just Shielding Winds as it was out first? And if they both go off would the first part of Undaunted then go off too since it’s reduced by 2 twice the 5 damage would be exactly 1.

Undaunted - Whenever exactly 1 damage would be dealt to Fanatic, prevent that damage. Whenever Fanatic would be dealt 5 or more damagefrom a single source, reduce that damage by 2.

Hmm, I think for the first one, you’re correct, Shielding winds would not prevent any damage since Fortitude reduced the damage.

For the second one, I think shielding winds and the latter half of undaunted would happen, it’s an either/or situation, so I don’t think you would then get to apply the first half of undaunted.
