Classic Bad Omen

Classic Bad Omen

Minecraft mod that restores instant Bad Omen when a raid captain would drop an ominous bottle.

Server-side / singleplayer. No dependencies. Clients do not need the mod.

Design

The mod does not reimplement captain / raid / distance checks.

It hooks at the moment vanilla is about to spawn an ominous bottle from a Raider. That path already encodes:

• patrol / outpost captain
• not participating in a nearby raid
• killed in a way that grants the bottle

Then:

1. Roll bad_omen_probability
2. On success, apply Bad Omen to the beneficiary (killer / pet owner)
3. Apply the configured bottle policy (drop_ominous_bottle)

Trial-chamber vault bottles and any non-raider source are untouched.

Config

File: config/classic-bad-omen.json (created on first launch)

{
  "enabled": true,
  "bad_omen_probability": 1.0,
  "drop_ominous_bottle": "otherwise",
  "levels": "stack",
  "duration_ticks": 120000
}

Key	Values	Default	Meaning
enabled	bool	true	Master switch
bad_omen_probability	0.0-1.0	1.0	Chance to apply Bad Omen
drop_ominous_bottle	otherwise, always, never	otherwise	See bottle policy below
levels	stack, drop	stack	stack = +1 per kill (max V); drop = same level as the bottle
duration_ticks	int	120000	Effect duration (vanilla bottle = 100 minutes)

Bottle policy (drop_ominous_bottle)

Value	On probability success	On probability fail
otherwise	Effect, no bottle	Bottle only (vanilla)
always	Effect + bottle	Bottle only (vanilla)
never	Effect, no bottle	No bottle

Warning for never: Captains will no longer drop ominous bottles. This removes one of the normal ways to obtain them.
Ominous bottles are required for Trial Chambers (ominous trials / vaults). Prefer otherwise or always if players still need that source, or provide them by other means.

Levels

• stack: pre-1.21 style: each successful kill increases Bad Omen by 1, up to level V.
• drop: uses the amplifier vanilla rolled on the bottle (I to V).

Test command

Summon a harmless raid captain (hold an ominous banner in main hand first):

/summon pillager ~ ~ ~ {PatrolLeader:1b}
/item replace entity @n[type=pillager] armor.head from entity @s weapon.mainhand
