Planting a bean may cause the following:

d100 - Effects

01 5d4 toadstools sprout. If a creature eats a toadstool, roll any die. On an odd roll, the eater must succeed on a DC 12 STR save or take 5d6 poison damage and become Poisoned for 1 hour. On an even roll, the eater gains 5d6 temp HP for 1 hour.

02-10 A geyser erupts and spouts the GM’s choice of liquid (water, beer, berry juice, tea, vinegar, wine, or oil) 6 spaces into the air for 1d12 rounds.

11-20 A treant sprouts. There’s a 50 percent chance it is hostile.

21-30 An animate, immobile stone statue in your likeness rises. It makes verbal threats against you. If you leave it and others come near, it describes you as the most heinous of villains and directs the newcomers to find and attack you. If you are on the same plane of existence as the statue, it knows where you are. The statue becomes inanimate after 24 hours.

31-40 A campfire with blue flames springs forth and burns for 24 hours (or until it is extinguished).

41-50 1d6 + 6 shriekers sprout. A shrieker is a human-sized mushroom that emits a piercing screech to drive off creatures that disturb it. When bright light or a creature is within 6 spaces of the shrieker, it emits a shriek audible to everyone in the area. The shrieker continues to shriek until the disturbance moves out of range and for 1d4 of the shrieker's turns afterward.

51-60 1d4 + 8 bright pink toads crawl forth. Whenever a toad is touched, it transforms into a Large or smaller monster of the GM’s choice. The monster remains for 1 minute, then disappears in a puff of bright pink smoke.

61-70 A hungry bulette burrows up and attacks.

71-80 A fruit tree grows. It has 1d10+20 fruit, 1d8 of which act as randomly determined magic potions, while one acts as an ingested poison of the GM’s choice. The tree vanishes after 1 hour. Picked fruit remains, retaining any magic for 30 days.

81-90 A nest of 1d4 + 3 eggs springs up. Any creature that eats an egg must make a DC 15 STR save. On a successful save, a creature permanently increases its lowest ability score by 1, randomly choosing among equally low scores. On a failed save, the creature takes 10d6 force damage from an internal magical explosion.

91-99 A pyramid with a base 12 spaces wide bursts upward. Inside is a sarcophagus containing a mummy lord and treasure of the GM’s choice.

00 A giant beanstalk sprouts, growing to a height of the GM’s choice. The top leads where the GM chooses, such as to a great view, a cloud giant’s castle, or a different plane of existence.
