You recall more about your past life as a druid. You have +2 to all elemental resistances and can cast the Flame Blade spell three times per rest, which summons a scimitar (or, if you choose, dual scimitars) of fire; these do fire damage instead of slashing damage and use the wielder's Wisdom instead of Strength for determining attack and damage bonuses. The swords are automatically equipped when created. At caster level 1, it has a +1 enhancement bonus and the flaming effect. Every five caster levels the summoned swords improve.
Probably functionally identical to the druid spell Flame Blade, except using character level instead of caster level.
Bug: The progression of the blades doesn't work as expected, after testing with a multiclass non-casting character (August 2025). At Dark Hunter 3 / Monk 2, the ability's tooltip listed the spell as 5th caster level, but the summoned blades were still +1. After another level of monk, the blades updated to +2 one level late. Later, the blades upgraded to +4 at level 11 instead of 10.
