All creatures entering, or starting their Turn in the affected area must make a Constitution saving throw or become Sickened for 1 Round.
Regardless of success, the affected area is considered Magical difficult terrain.
The affected area blocks sight beyond 5ft.
If a creature has 5ft of web between them and an opponent, they are considered Shrouded.
If a creature has more than 5ft of web between them and an opponent, they are considered Concealed.
If two or more Choking Cobweb spells overlap the same area, the overlapping area functions similarly to Web, except the web does not need to be anchored, but can be if so desired, and the web is not flammable.
Additionally, the penalties of difficult terrain are doubled.
Finally, any creature who becomes Sickened is instead Nauseated, and also take 1d4 Constitution damage.
