Notes
- condition has two possible effects: it can restrain, that is, prevent a character from moving, and it can deal damage.
- There is a saving throw for restraining, and restraining may happen
- when the spell is cast
- at the beginning of a character's turn
- when re-entering the area.
- Damage is dealt only at the beginning of the turn when a character fails the save and also had the condition before the turn.
- An affected character seems to lose all movement speed, but actually the duration of this condition is whilst on surface, which means that movement speed is returned if the character escapes the surface for example by using . As a comparison, has duration of 1, so escaping the webbed surface does not return the movement speed.
- If a character is dealt damage by a weapon (at least spells and fists don't seem to have this effect) earlier in the same round, it is not affected when the spell is cast. However, if later in the same turn such a character moves in the affected surface, they need to make the saving throw.
