This section mostly provides counterparts to the Rogue's Penetrating Strike ACF from EtCR to keep precision damage relevant against the many undead and golems of the campaign setting, but there are also some other bits.
Factotum
As scholars of all and nothing, Factotums are found across all civilized parts of the Demiplane.
Class Skills: Factotums do not gain access to Knowledge (Ravenloft).
ACF: Apothecary:
Where the default factotum may carry around lucky charms and holy symbols, you sneer at such superstition. You instead keep a stash of alchemical ingredients, poultices, tonics and syringes around, all based on science, on things you can touch and feel.
This ACF is especially widespread in atheistic Lamordia, but it may also be found in other lands and among other individual factotums of dubious piety.
Acquired at: 5th Level
Replaces: Opportunistic Piety, and subsequent extra uses of it at 10th, 15th and 20th level
Benefit: While preparing your spells of your Arcane Dilettante feature at the beginning of the day, you also mix some concoctions. These concoctions work like potions of a total value of your (Int mod + Wis mod) x 50gp, selected from the potion lists in the DMG/SRD. Concoctions spoil at the beginning of the next day and are worthless for the purpose of selling them.
Your virtual money limit for daily concoctions increases by +250gp at 10th level, +750gp at 15th level and +2,100gp at 20th level (non-cumulative).
Ninja
While what one expects to be the typical ninja is generally only found within the oriental domain of Rokushima Taiyoo, there are also other shadow warriors who blend a rogue-like training with supernatural tricks, from the spies of the Dilisnya network to the Ba'al Verzi assassins to individual crazed serial killers.
ACF: Yurei Slayer:
Acquired at: 4th Level
Replaces: Great Leap
Benefit: Whenever you attack a creature type that is immune to Sudden Strike damage while it is denied its Dexterity bonus to AC, you still gain half of your Sudden Strike dice as bonus damage.
Scout
Scouts are widely spread through the wilderness of the Demiplane, from the spy network of Count Strahd von Zarovich to the hunters of such wild and unearthly places as Nova Vaasa or the Frozen Reaches.
ACF: Peacekeeper of the Burial Woods:
Acquired at: 4th Level
Replaces: Bonus Feat
Benefit: Whenever you attack a creature type that is immune to Skirmish damage while you otherwise qualify for Skirmish bonus damage, you still gain half your Skirmish dice (minimum of 1d6) as bonus damage.
Spellthief
Spellthieves are mostly found wherever arcane magic flourishes in general, such as in Darkon or Hazlan.
ACF: Grabber of Curious Grave Goods:
Acquired at: 5th Level
Replaces: If you select this feature, your Sneak Attack damage does not increase at 5th level. Thereafter, your Sneak Attack damage is always one die smaller than it otherwise would be for your Spellthief level.
Benefit: Whenever you attack a creature type that is immune to Sneak Attack damage while you otherwise qualify for Sneak Attack bonus damage, you still gain half of your Sneak Attack dice as bonus damage.
