The chalice can be drunk by players. Its effects are random, but include:
- Temporarily boost Crafting, Fletching, or Thieving by 1 level.
- Temporarily boost combat ability (Attack, Strength, and Defence) by 4 or reduce it by 3.
- Heal or damage the player: healing players up to 490 life points or damaging them from 30 to 600.
Damage seems to be based on a percentage of the player's life points, at two levels: 5% damage and 60%. It also seems that player with a high amount of life points have lower chances of being damaged by drinking from the poison chalice.
This could be used similarly to nitroglycerin. It can be a potent item for those who use Dharok's set as it damages a lot (up to 600), but it is very risky as it may heal or lose too many life points. After an update the killing effect of this potion was removed, your health will not fall below 25.
