Similar to, but weaker than, the potion of master thievery, this potion also grants the thief drinking it temporary increases in levels, hit points, and skills, if he or she is of 9th or lower level prior to drinking it, as shown below:
| Level of Imbiber |
Levels Bestowed |
Added Hit Points |
Increase In each Skill |
|---|---|---|---|
| 1st-3rd | 5 | 5d6 | +20% |
| 4th-6th | 4 | 4d6+1 | +16% |
| 7th-9th | 3 | 3d6+2 | +12% |
| 10th-12th | 2 | 2d6+3 | +8% |
As with the potion of master thievery, the individual acts in all respects as a thief of the higher-level gained after drinking the potion, with the increase in thieving skills being equally spread across all categories by the bonus shown. Damage sustained is taken from additional temporary hit points gained first. The effects of the potion last for 1d4+4 turns.
