Several size Large flying creatures are attacking my party. I'd like to cast Web to prevent their escape and limit their ranged advantage.
Relevant parts of the Web spell description say:
The webs fill a 20-foot cube from that point for the duration. [...]
If the webs aren't anchored between two solid masses [...] the conjured web collapses on itself
I can get at least two of these creatures to be affected by the spell's area of effect. Would they count as the 'two solid masses' the description requires?
