The caster and their allies within a 20 foot range appear to be wiped out in a spectacular fashion. Roll 1d6 to determine the type of demise:
1d6 Result
1 Backfire: Apparent spell backfire, turning everyone into geese still dressed like them. They scatter.
2 Thunderstrike: Massive thunderstrike disintegrates everyone. Only their feet remain in their boots, smoldering.
3 Dragon: The casting process attracts a fire or acid breathing dragon, leaving behind only bleached skeletons.
4 Mega Hand: A massive mage hand flies in and squishes them all into a fine paste, leaving a pool of gore.
5 Old One: A giant squid tentacle bursts from a nearby body of water or the ground, wrapping around everyone and pulling them into a dark abyss.
6 World's Fury: Rocks fall, crushing and burying everyone-or a bottomless sinkhole opens up, swallowing them whole.
The party gains 30 ft of movement to invisibly vacate the scene while their deaths are playing out. Actions besides movement break the illusion. Otherwise, it follows the rules of Major Image.
AT HIGHER LEVELS:
When you cast Total Party Kill using a spell slot of 3rd level or higher, the range of the spell expands by 10 feet for each slot level above 2nd. However, the illusion always affects the smallest possible area to include all allies within range.
BACKGROUND This was archmage Zaelric's and his wife Qradora's usual way of leaving parties and conclaves when they had had enough. Up until a gargoyle statue fell onto them, and no one around took it seriously.
