 Description   

The thorns does not work against some monsters such as slimes. This has been reported in MC-4609 and MC-4619 but it is still bugged (at least for me).

To verify this, I manually created a level 127 Thorns enchantment and tried it against different mobs. Zombies, Skeletons, Zombie Pigmen and Spiders instantly died. They were instantly killed on first contact, none of the them required a second time for the Thorns enchantment to work.

However, the slimes never got hurt once even though I have spawned around 64 Large Slimes and went around getting attacked by them for 5 minutes or so, with the same enchantment level.

The enchantment level 127 was obtained using a NBT file editor. A level 3 Thorns enchantment (maximum level obtainable without editors) still does not damage slimes.

Update: (Thanks to Mike B for the comprehensive coverage)

Mobs affected: Zombies, Cave Spiders, Spiders, Skeleton, Wither Skeletons, Zombie Pigmen, Endermen and Silverfish.

Not affected: Wither Boss, Enderdragon, Magma Cube, Slimes, Witch, Wild Angry Wolf, Creeper, Blaze and possibly Iron Golem. (Creeper should not be affected because they're dead after they attacked)

Fixed, with the caveat that Witches' thrown potions do not cause Thorns splashback, as it is the potion causing the damage, not the Witch itself.

Is this still a concern in the latest Minecraft version 14w11b? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

i think the blazes are having this glitch because of them having 2 types of attacks ranged and touching maybe that they arent adapted to thorns?

Comment by Kelven Lee [ 11/Apr/13 ]

For now, I'm just using Dinnerbone's tweet that the thorns work on everything. The link to his tweet was in a previous comment.

And I don't know if Witches should be affected by Thorns as they attack with splash potions. Maybe Witches could be affected when he uses a splash potion of instant damage, but I don't know.

Creepers shouldn't be affected by Thorns, as they self-destruct to kill you.

This still occurs in snapshot 13w03a. I used a level III thorns enchantment on all diamond armor on all possible hostile mobs except I couldn't get the Iron Golem to attack me from upsetting villagers, thought that was a feature.

Mobs affected: Zombies, Cave Spiders, Spiders, Skeleton (from projectiles?), Wither Skeletons, Zombie Pigmen, Endermen, and Silverfish.

Not affected: Wither Boss, Enderdragon, Magma Cube, Slimes, Witch, Wild Angry Wolf, Creeper, and Blaze (not really affected unless you stand near them but I think that was them taking damage from their own attack).

I didn't realize until after I rendered the video that I didn't get record blaze and silverfish.

Certainly confirmed.

Comment by Zach Smith [ 31/Dec/12 ]

I think this must be solved. I had a level 100 Thorns on a flatworld also and it didn't affect slimes.

Comment by Kelven Lee [ 24/Dec/12 ]

Well, Dinnerbone said in one of his tweets that Thorns should work against everything...

Quite true...

Comment by Zuriki [ 24/Dec/12 ]

By that logic arrows shouldn't work. Or punching. Definitely sounds like a bug to me.

Comment by Kumasasa [ 24/Dec/12 ]

Maybe intended ? Ever tried to stab a jello ?
