1. You Cannot Bind Full HP Monsters
If the target has ≥99% life, Bind Demon has a 0% chance to succeed.
You must damage the monster first.
Even 1% damage is enough to unlock the mechanic.

2. The Tooltip Does NOT Show the Real Chance
The displayed % only shows: Base Bind Chance (from skill level) + Death Mark synergy
It does NOT include the monster life bonus.
The effective in-game chance is calculated from three parts combined.

3. 1st: Bind Demon % Chance Is NOT Linear
Base chance is calculated via: 7 + 24.2 × L / (L + 6)
Where L = Bind Demon level (with +skills).
Early levels give strong gains. Later levels scale slower.
It asymptotically approaches ~29% base chance.

4. 2nd: Death Mark Adds Hard Points Only
Synergy formula: +1% per hard point in Death Mark

5. 3rd: Missing Monster Life Adds Directly
The real formula adds: (100 − Current HP%)
Example: 90% HP > +10% chance and 1% HP > +99%
The lower the monster’s life, the stronger bind becomes.
(This part is NOT shown in the tooltip.)

6. There Is (Almost Certainly) a 100% Cap
Because the formula can exceed 100% at low HP, the game very likely caps success chance at 100%.
At very low monster life, Bind becomes practically guaranteed.

7. 197 Monsters Can Be Bound
The formula is identical for all valid targets.
Bind does not scale differently per monster type — only HP% changes the outcome.

8. Consuming monsters grants bonuses
Each bound monster can also be consumed.
Consuming a monster grants you between 1 and 3 bonuses including auras.
Possible auras are: conviction, holy fire, cleansing, vigor, mediation

9. Bonuses are not random
Each monster has fixed possible bonuses with a range for the effective value.

10. Lister is not only good being your bound demon
Lister grants the highest damage boost for all consumable monsters in the game.
Formular is: damagepercent = Slill-Level × 5 + 150
With lvl 20 you get 250% extra damage. Maybe nice for pvp.

All the information is based on the gamefiles. If they don’t have changes in the code it should be true. But the experience of the d2jsp community will hopefully confirm it.

Baal Subject 2 (= super unique of baal wave 2) is in the list of bindable monsters. This means he can be bound.

When you consume him, he gives you:
poisonresist: 3 x skill level + 20
max poison res: Min(skill level / 2 + 2 , 10) (which means max 10% additional poison res)
minus enemy magic resistance: skill level + 15
