Subclass Changes from the Horror UA to Ravenloft: The Horror's Within
The Shadows of Sithicus event PDFs were accidentally released publicly recently, and they included premade level 3 characters all using subclasses from the book. Here are the changes I've seen, avoiding directly copying the text.
#Reanimator (Artificer)
- ~~It's Reanimated Companion was buffed slightly: its AC seems to be calculated now as 13 + your Intelligence modifier (the listed premade block has an AC of 16 and the Artificer's modifier is +3).~~ The AC calculation remains the same, my bad. Its explosion still does friendly fire damage.
- Its Jolt of Life was changed. Instead of regaining a single hit point, the target instead regains a number of hit points equal to your Artificer level. The damage is now 2d4 Lightning, increasing to 3d4 at level 11 and 4d4 at level 17, and you can now choose the targets in the Emanation instead of it being each target within it!
- Expanded Spells unchanged.
#Grave Domain (Cleric)
- Path to the Grave now has its additional damage be equal to your Cleric level instead of a 1d8 + Cleric level.
- Circle of Mortality's Pull of Death feature now works on anyone who is missing hit points instead of requiring them to be Bloodied. Return to Life now allows you to cast Spare the Dying as a bonus action.
- Chill Touch is gone, likely replaced with Spare the Dying as part of Return to Life. Bane is also missing, replaced by False Life.
#Hollow Warden (Ranger)
- Wrath of the Wild now no longer activates when casting Hunters Mark. Instead, you can use your bonus action to expend a Favored Enemy use to transform for a 1 minute duration. The AC bonus is the same, but Unnerving Aura now frightens a creature for 1 turn on a failed save rather than taking away an action/bonus action, and it gains a new feature called Prowling Retribution: When you or an ally take damage from a creature within 5 feet of yourself, you can make an Opportunity Attack against them.
- Wrathful Smite still part of Expanded spells.
#Phantom (Rogue)
- Unchanged from the UA, unfortunately.
#Shadow Sorcery
- Level 3 feature has reverted to the 2014 version but modified, now called Power of Shadow. Eyes of the Dark gives you 120 feet of Darkvision and 10 feet of Blindsight, as well as the ability to see through spells you cast that create Darkness. Strength of the Grave returns, now giving you a number of hit points that I'm unsure of the calculation: sheet says six, so I would guess Sorcerer level (3) + your Charisma or Constitution modifier (could be either, sheet has +3 mod for both).
#Bonus
The Haunted One Background returns, with a new origin feat called Survivor: you can reroll an initiative score below 10 on the d20, and once per long rest can add a bonus to a failed saving throw against being charmed or frightened likely equal to your Proficiency bonus.
