Blood Gems — Secondary Stats — Bloodborne
Blood Gems — Secondary Stats — Blood gems, Bloodborne. Choose the dungeon and enemy that make your desired secondary effect easier to obtain.

Native effect families
| Dungeon | Examples of native secondary effects |
|---|---|
| Phumeru | Flat physical damage; stamina cost; counterattack; charged attacks; HP-dependent physical bonuses |
| Loran | Flat fire or bolt damage; poison; rally; regeneration; damage against beasts or Kin |
| Isz | Flat physical, fire, bolt or arcane damage; many HP, poison and utility effects |
Some enemies determine their secondary effect
| Enemy | Characteristic secondary effect |
|---|---|
| Brainsucker | Flat arcane damage |
| Loran Cleric | Flat fire damage |
| Evil Labyrinth Spirit | Physical damage at low HP |
Do not confuse possible with common
The dungeon supplies a list of possible effects; the enemy also has its own rules. A native effect does not necessarily have a high probability. Check the primary / secondary effect pair before choosing a route.
Some enemies strengthen the secondary effect: Labyrinth Madman gems can therefore compete with gems that have a higher primary percentage.
Gem effects and acquisition
The dungeon and enemy determine possible secondary effects. Brainsuckers guarantee flat arcane; Loran Clerics guarantee flat fire.
Choose the primary / secondary effect pair before the glyph.
A stronger secondary effect can compensate for a lower primary percentage; compare the flat addition separately.

- An effect native to a dungeon does not necessarily have a high probability. An enemy with a fixed secondary effect is more predictable.
