Multiattack

The purple slime makes two spike attacks.

Spike

Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 6 (1d8 + 2) piercing damage and 10 (3d6) poison damage. In addition, the target must succeed on a DC 14 Constitution saving throw or its Strength score is reduced by 1d4. The target dies if this reduces its Strength to 0. Otherwise, the reduction lasts until the target finishes a short or long rest.
