Blood Roses are corrupted flowers who appear to despise Alice's appearance and attack her by shooting out red thorns from their petals. There is no real trick to defeating the roses, except for avoiding their first barrage of thorns. Afterwards they will be lucky to even hit Alice. Walking up to the vicious flora will cause them to swipe at Alice. One throw of the Vorpal Blade kills them easily, and a shot from the mallet can kill them in three hits.
