vile aztec goose curse

the evil aztec goose gods used this spell to create more of there kind, but it requires the sacrifice of a goose, so they do not use it very much. during the casting you must kill the goose that is the material component in a long ritual sacrifice, and then scream gibberish words while dancing around and wave the target's finger in the air. at the end of the casting time they must make a con save or get the curse. if they succeed on the save you did not sacrifice the goose right, so it comes back to life and is hostile to you. read below to see what happens while they have the curse.

• day 1. on the first day the creature has the curse, they notice nothing except for the curse eating away at there flesh, which makes them take 1 acid damage at the end of every hour. also, hieroglyphic marks that look like geese appear on there limbs.
• day 2.  on the start of the second day they must make a con save or progress to stage two. if they succeed, they stay in stage one for that day but must make the save at the start of the next day. if they fail, the curse gets stronger. now they take 2 acid damage at the end of every hour, and they there bones rearrange, causing a -10 to there speed.
• day 3.on the start of the third day they must make a con save or progress to stage three. if they succeed, they stay in stage two for that day but must make the save at the start of the next day. if they fail, the curse gets even stronger! they suffer the effects of stage one and two, but the acid damage is 3. also there flesh and bones warp further, causing them to have a disadvantage on attack rolls and ability checks.
• day 4. on the start of the fourth day they must make a con save or progress to stage four. if they succeed, they stay in stage three for that day but must make the save at the start of the next day. on stage four, they have the effects of 1, 2, and 3, but the acid damage is 4. the curse is real bad now. they also act as if under the confusion spell in combat, because there brain is turning to mush.
• day 5.on the start of the 5th day they must make a con save or progress to stage five. if they succeed, they stay in stage four for that day but must make the save at the start of the next day. in stage five, the curse is super duper bad, they have the effects of 1, 2, 3, and 4, but the acid damage is 5, and they take 3 necrotic damage when they move or take an action because the curse is consuming there soul.

a creature killed by this spell turns into a angry goose that will track down the caster and attack it, because it does not like being made with a curse. the target will turn back to their normal selves with half hit points at the end of five days, because the curse is wimpy when not cast by an immortal goose god. this curse can be turned off by any helping spell, such as protection. use this spell to annoy people you don't like.
