Nimu - Just a note about web before you cast it. The description of web says:
If the webs aren't anchored between two solid masses (such as walls or trees) or layered across a floor, wall, or ceiling, the conjured web collapses on itself, and the spell ends at the start of your next turn. Webs layered over a flat surface have a depth of 5 feet.
If you are going after the same ones that Hornet is - that means that they are in the river already. In this case there would be nothing to anchor the web to. So I'm thinking you would prefer sleep in that case. But you sort of left it open - I'm not quite sure when/if I should switch it to sleep. So please clarify.
Just to be clear - there are 4 goblins holding prisoner ropes. Each prisoner has a goblin with a rope.
And to all - the more precise you can be about which goblin or gnoll you attack or what bush or rock you move to the better. It leaves less up to my guesswork or dice rolls. My guessing or dicing may not be what you wanted.
