Searing Barrage deals 5 damage to target creature.
Adamant — If at least three red mana was spent to cast this spell, Searing Barrage deals 3 damage to that creature's controller.
It emerged from the coldest depths of Lochmere only to face the fires of Irencrag.

Adamant effects check what mana was actually spent to cast a spell. If an effect allows you to spend mana “as though it were mana” of any color or type, that allows you to spend mana you couldn't otherwise spend, but it doesn't change what mana you spent to cast the spell.

If an effect allows you to cast a spell without paying its mana cost, you can't choose to cast it and pay unless another rule or effect allows you to cast that spell for a cost. Similarly, you can't waive a cost reduction unless that effect says you may.

If the target creature is an illegal target by the time Searing Barrage tries to resolve, the spell won't resolve. No player will be dealt damage, even if you spent three red mana.

If you copy a spell that has an adamant ability, no mana was spent to cast the copy at all, so that ability won't apply.

Searing Barrage's adamant ability causes it to deal additional damage. It doesn't replace the damage dealt to the target creature.

If an instant or sorcery spell has an adamant ability, you perform the spell's instructions in order. You don't perform the adamant instruction before the spell resolves or before any other effects printed above it.
