Question 1

What is the difference between Potion, Splash and Lingering potions?

Accepted Answer

Potions are drunk. Splash potions are thrown — the cloud applies the effect to anyone in the burst radius. Lingering potions create an area-effect cloud lasting ~30 seconds. Tipped Arrows are crafted from a Lingering potion + 8 arrows. Ominous Bottles trigger raids when drunk.

Question 2

How does CustomPotionColor work?

Accepted Answer

CustomPotionColor is an integer encoding RGB. Pick any color with the wheel and the generator outputs the right integer (Legacy NBT) or hex (Item Components 1.20.5+).

Question 3

When should I use Item Components vs Legacy NBT?

Accepted Answer

Item Components — for Minecraft 1.20.5+. Legacy NBT — for 1.13–1.20.4. The generator emits both syntaxes side by side.

Question 4

Can I make potions with infinite duration?

Accepted Answer

Yes. Set duration to -1 in Item Components (1.20.5+). Legacy NBT falls back to 1,000,000 ticks (~13.8 in-game hours).

Question 5

What are Ominous Bottles?

Accepted Answer

Added in Minecraft 1.21 as part of the Trial Chambers update. Drinking gives Bad Omen — entering a village triggers a raid.

Question 6

Will this generator work on Bedrock Edition?

Accepted Answer

Partially — the /give syntax is Java Edition. Most effect IDs match between editions, but exact commands are Java-only.
