Our party has opened war on the Drow capital city, with a rag tag army of Moon Warriors, Pirates looking to make a name for themselves, Forest Rangers, and our not quite stable party of an Eladrin Warlock with multiple personalities, a half orc barbarian with Wonder Woman's tiara, a panther-halfling hybrid rogue, a Giant Powered Kobold, and a Yuan-ti/Gobling hybrid Bard against the forces of the Drow Nation. Numbers are not in our favor, especially as our allies from the Wizard City can't arrive until we destroy the giant spider golem the city has.
Combat is rough, so our party's opening gambit...is to throw out an egg in the center of the city that becomes a gargantuan Spawn of the World Serpent, then run back to our battle. It spawns with only the golem between it and the Arcane Academy, and next to a giant spider nest spawning giant demon spiders once a day.
The first couple days are a bit rough as the tide of battle is not with us, and the serpent, while destroying a large area of downtown, is taking a lot of damage and missing it's attacks on the mechanical and demonic spiders...
So we throw two more eggs into the mess, and continue on with our battle as the Pirates manage to reach us where our part of the army had come up from the underground, the eastern front is still rough but sorta even, and the center of town has had a kaijuu battle going for half a week now.
That sounds really awesome!
