Javelin
A polearm whose critical bonus increases as the wielder's HP falls below the stated threshold.
How it works
The table lists Javelin at attack 18 and critical 4. Its low-HP critical modifier is +5 plus 1.5 times each percentage point of HP reduction under 30% HP. The accompanying description summarizes its effect as delivering critical strikes when the wielder is in poor health. No maximum value or other activation condition is supplied in the passage.
