Crimson armor

Crimson armor is a pre-hardmode set of armor. It is the Crimson equivalent of Shadow armor, and like it, when the full set is visible, a trail of red bubbles follows the player. It requires 60 Crimtane Bars (240 Crimtane ore) and 45 Tissue Samples to make. The set bonus is greatly increased life regen, which is shown by faint red pulses in quick succession around the player while it is in effect. When the set bonus is activated, each red pulse will regenerate 1 health, and the pulses seem to be more frequent when the player stands still. Every second without taking damage will increase the life regen, which makes the Nurse less useful in pre-hardmode if you are not fighting bosses or waves of enemies. Due to this effect, this set of armor is arguably the best set of pre-hardmode armor, even surpassing Molten armor.

Trivia
