Here's an idea for an artifact potion:
virile potion "Rolf's Sweat" (20s)
When drunk, all of your attributes are increased by 5 (regardless of B/U/C status), then it disappears. It also gives 500 points of satiation and heals you by MAXHP/3 (or fully heals you if MAXHP-MAXHP/3< current HP) when drunk. Throwing or using it does nothing. If drunk when at (or very near to) full health, it will increase your maximum HP by some- the same way that drinking a blessed potion of extra healing when at full health will do that.

You spend some time with Skriek, the cloaked ratling, who seems to enjoy your company. The sky is now very clear. The sun burns down on you.
You talk to Skriek, the cloaked ratling.
"Yer alternatives are locked, wisehead!" Skriek, the cloaked ratling, misses you. Skriek, the cloaked ratling, misses you. Skriek, the cloaked ratling punches through your armor and hits you.
