When you join this order at 3rd level, you learn the Rite of the Dawn as part of your Crimson Rite feature. When you activate the Rite of the Dawn, the extra damage dealt by your rite is radiant damage. Additionally, while that rite is active on your weapon, you gain the following benefits:
Your weapon sheds bright light out to a radius of 20 feet.
You have resistance to necrotic damage.
When you hit an undead creature with a weapon for which the Rite of the Dawn is active, you roll an additional hemocraft die when determining the extra damage from the rite.
Starting at 3rd level, you learn to master blood curses. You gain an additional use of your Blood Maledict feature. In addition, your blood curses can target any creature, whether it has blood or not.
Upon reaching 7th level, at the start of your turn, you can magically step into the veil between the planes as long as you aren’t incapacitated. You can move through other creatures and objects as if they were difficult terrain, as well as see and affect creatures and objects on the Ethereal Plane. You take 1d10 force damage if you end your turn inside an object.
This feature lasts for a number of rounds equal to your Hemocraft modifier (minimum of 1 round). If you are inside an object when it ends, you are immediately shunted to the nearest unoccupied space and you take force damage equal to twice the number of feet you moved.
Once you use this feature, you must finish a short or long rest before you can use it again. You can use Aether Walk twice between rests starting at 15th level.
Starting at 11th level, your Brand of Castigation exposes a fragment of your foe’s essence, leaving them vulnerable to your Crimson Rite feature. Whenever you hit a creature with a weapon for which you have an active crimson rite, you roll an additional hemocraft die when determining the extra damage from the rite. Additionally, if a branded creature has the Incorporeal Movement trait or a similar feature, it can’t move through creatures or objects while branded.
At 15th level, you hone your hemocraft to tear corruption from the minds and bodies of your allies — and to punish those responsible for it. You gain the Blood Curse of the Exorcist for your Blood Maledict feature. This doesn’t count against your number of blood curses known.
Upon reaching 18th level, you learn to protect your fading life by reabsorbing the energy you feed to your weapons. If you have one or more crimson rites active and you are reduced to 0 hit points but don’t die outright, you can choose to have all your active crimson rites end and drop to 1 hit point instead.
