A permanent stat-buff potion — raises Constitution 1-4 points, limited to two doses ever, 'because cheating.'
The Superb Constitution Buff Potion is an orange, bubbly stat potion Mordecai brews for Princess-Donut, permanently raising Constitution by a random one to four points. Only two of any such stat potion may ever be drunk in the dungeon — the system's tooltip snarks 'because drinking more would be cheating. And if anyone is going to cheat, it's going to be me.' 'Superb' quality is the best Mordecai can make (potentially +4); he warns the party not to drink any found stat potion unless it's labeled Superb.
Donut takes both hers — a disappointing +1 then a +3 — netting +4 for a base Constitution of eight (21 with buffs). A rarer, unrestricted 'Cosmic Buff' raises a random stat by 10, but its recipe is beyond Mordecai.
An orange, bubbly potion; the fan-box version glimpsed later glows with a twinkly strobe-like aura.
The party's core permanent stat-raising consumable, rationed to two lifetime doses per crawler.
