Weapons - Status Effects
Status afflictions have 3 chance levels:
Low: ~30% chance
Often: ~50% chance
Always: 100% chance
Most weapons have a low chance for affliction.
The exceptions are Kazikli, which often afflicts curse; Swordbreaker, which always debuffs enemy STR; and coin weapons (8/16/32bit).
Coin weapon affliction chances are based on their level:
8bit: Low (~30%)
16bit: Often (~50%)
32bit: Always (100%)
Curse
Stone
Kaladanda ─ Low
Murgleis ─ Low
Gold Cross ─ Depends on level
Sculptor's Chisel ─ Depends on level
Silent Calamity ─ Depends on level
Poison
Debuff enemy STR
Library Books
I added the effects of OD's Library books to the fextralife wiki. Exact stats and required map completion % are listed there.
https://bloodstainedritualofthenight.wiki.fextralife.com/Orlok+Fahrenheit+Dracule+(O.D)
The main takeaways are:
Effects that aren't shown in-game (attack speed, EXP etc) all increase their stat by 20%.
The Tome Of Conquest actually incorporates 4 books, not just 3. The secret book is Tactician's Tome, which gives +20% EXP gain.
