@JeremyECrawford say you have a huge or larger creature and a druid, shaped to a water elemental, stops in its space. Can that huge creature attack the elemental druid? https://t.co/q5gbXYPG8s

The Water Form trait of the water elemental doesn't inhibit attacks made by or against the elemental.

If the trait inhibited attacks, it would say so. #DnD https://t.co/XwS499OPG7
