Mustard Jellies are one of the more dangerous varieties of slime. They are immune to normal weapons, electricity, piercing damage and many other forms of attacks, especially missiles, cold and magic. They are also immune to backstab with any weapon. They are most vulnerable to fire, acid, and slashing damage. They have the ability to poison and slow their enemies.

Shapeshift Mustard Jelly

It is possible to change into a Mustard Jelly, through Polymorph Self or the Cloak of the Sewers. The polymorphed character obtains the following stats:

• Resistances: 30% Slashing damage, Baldur's Gate I & II Classic
  This icon indicates content from all original Baldur's Gate games, extensions included. 60% / Baldur's Gate I & II: Enhanced Editions
  This icon indicates content from all Enhanced Editions of the Baldur's Gate games. May situationally encompass Siege of Dragonspear and The Black Pits I & II content as well. 30% Crushing, 100% Piercing, 85% Missile, 100% Poison damage, 100% Electric, 50% Cold, Baldur's Gate I & II Classic
  This icon indicates content from all original Baldur's Gate games, extensions included. 100% / Baldur's Gate I & II: Enhanced Editions
  This icon indicates content from all Enhanced Editions of the Baldur's Gate games. May situationally encompass Siege of Dragonspear and The Black Pits I & II content as well. 125% MR; other modifiers may apply, from equipment for instance
• Armor Class: 4 – modifiers may apply
• Strength: 14
• Dexterity: 9
• Movement Speed: 4 – includes the form's innate Boots of Speed effect. Like with the boots, one Haste effect can be applied on top, reaching up to a speed of 8. (Humanoids have a default speed of 9)
• Weapon: Magical +3, ranged, 5d4 (crushing), causes Slow for 200 seconds (a little over 33 rounds) unless saved vs Breath with -2 penalty, applies a Poison effect for 5 rounds unless saved vs Death with +2 bonus (1 dmg every 2s). Effects bypass MR and cannot be dispelled. Unusually, both Strength and Dexterity provide bonuses to THAC0 for this weapon, and it also receives bonus damage from Strength.
• Spellcasting: Disabled, except for innate and item abilities
• Weapon immunity: Non-magical
• Immunity to effects:
  • Berserk
  • Charm Creature
  • Confusion
  • Hold creature
  • Level drain
  • Panic
  • Paralyze
  • Petrification
  • Poison
  • Power Word, Sleep
  • Power Word, Stun
  • Slay
  • Sleep
  • Stun

This list is to be added to pre-existing immunities, such as those coming from equipment for instance.

The 100% magic resistance granted by this form translates to immunity to Beholder rays, but not Devour Brain of Mind Flayers.

Note: In the original BG2, the jelly from the Cloak of the Sewers is much less resistant than the jelly from the Polymorph Self spell. Only use the former if you need 100% resistance to Missile damage, its one strength.

Trivia

• The offical website for the original game, now archived, had – in addition to some combat-related statistics – the following information about these slimes:

  The monstrous amoeboid mustard jelly is far more dangerous than the ocher jelly.^[sic] Mustard jelly is translucent, and very hard to see until it attacks. The only clue to its presence is a faint odor, similar to blooming mustard plants. Once it does attack, it may be seen as yellowish brown in color.

  The size was given as 9 to 12 feet in diameter.

While the Mustard Jelly form provided by the Cloak of the Sewers and the Spell form is immune to almost all Gauth and Beholder eye blasts/rays, with Sword Coast Stratagems and the "Smarter Beholders" component that is not completely true. The three Hive Mother creatures in the game files are able to fire a unique Cause Serious Wounds ray that bypasses magic resistance, saving throws and spell level protections. Testing indicates at least one blast every other round is generated, dealing an average of 22 Magical damage each time. In addition, the Hive Mother's anti-magic ray will drain charges in all equipped items and quick slot items, even in Jelly Form. If soloing the Hive Mother as a Jelly, the creature will deal more damage to you faster than you are able to deal to the Hive Mother. It is also likely that the creature will protect itself from magical weapons as well, and the polymorph duration will wear off before you can kill it with a Mustard Jelly attack weapon.
