It Came from the Sky!

From HERE

Roll d30 if your players are futzing around in the wilderness boring you to death, and inflict one of the following random encounters on them ...

1. A silver bird dropping silver daggers (low quality, but useful given the plague of apparitions in the neighborhood)

2. A tiny meteorite (1% chance of hitting somebody)

3. The sound of trumpets (all LG characters receive bless for 24 hours)

4. Waves of crimson sound that warn of … Murder!

From HERE

5. A red dragon spelling out “Eat at Joes” in smoke

6. A green luminescence that causes all plant-life to grow wild (per entangle), causes 1 in 10 trees to turn into treants, and heals 1d6 points of damage to all living things

7. Acid rain (1d6 acid damage per round, item saves for objects, lasts 1d6 minutes)

8. A silver canister of the mi-go (holds the brain of a 1d4+3 level magic-user)

9. A frozen black sphere (when it thaws in one minute it becomes a black ooze)

10. 3 and 20 blackbirds, recently released from a pie and bent on revenge against humanity (treat as enraged bat swarm with 2 attacks per round)

From HERE

11. A flight of pegasi, willing to give good characters a lift (I won’t say exactly what they’ll do to the evil, but it involves gaining altitude first)

12. A senile old giant owl who has mistook the halfling or gnome for a giant rat

13. A WW1-era biplane with a confused pilot

14. A disk of glowing orange metal crewed by 20 ultra-troglodytes (troglodytes in shiny orange jumpsuits with bulging brains, genius IQ’s and psychic powers)

15. An errant catapult stone (1% chance it lands on a character, dealing 10d6 damage)

From HERE

16. A sylph floating gently to the ground, love in her eyes and a song in her heart - she is soon joined by many others, who put on an impromptu ballet until a bunch of satyrs show up to ruin everything

17. A flight of seven harpies with a barbed net

18. The head of a frost giant, recently knocked from its should a few miles away by the hammer of the mighty Thor (or whatever native giant species and thunder god works in your campaign)

19. Confetti – it rains for hours

20. A rain of frogs, thrown into the atmosphere by a water spout

21. Sky pirates on a flying clipper – they bungee down to attack and plunder

22. An angel of the Lord, with grave tidings – the nearest metropolis is to be laid low for its sins

23. Two dozen giant bees, looking for a new home, their old one having been sacked by a clan of werebears

24. A holy sword, which embeds itself in the ground; it can only be removed by the rightful
Emperor-Pope of All Paladins (first paladin to 20th level can claim it)

From HERE

25. A black comet that sends out waves of revulsion and decrepitude

26. A black cloud, moving fast and against the wind and carrying with it the sounds of a clash of swords – perhaps a combatant will wing down to pick up the adventurers as reinforcements

27. 15 bird men – they seek ornaments for their queen, who is brooding

28. The Imam of the Jinn, on a magic prayer rug (treat as magic carpet), seeking converts to the Lawful Neutral faith and warriors for his crusade against the efreet

29. Mana from heaven (treat as triple strength create food spell)

30. A storm giant’s castle on a floating island; it’s on a crash course that will cause havoc and destruction about one mile from here (and it creates one heck of a great dungeon to explore)
