Not all that play multiple systems are for the new hotness. We are rather character driven in our games and prefer longer campaigns, and we play multiple systems.
Yep, I changed the phrasing of the question after I wrote the answers. I'll remove the 'besides'. Thanks!
Edit: I could not change the question, so I added another poll result of 1. :)
Good question. Why limit your potential for the next day because you used a lot of HD today, especially when you can just long rest and fully heal?
My guess is because they made long rests kinda silly with a full heal already. They should have changed that instead of making short rest healing...
What you do is take out the first target, go unnoticed and have combat end, and then surprise the next target by starting combat again.
Once combat starts and enemies are aware it started, they can no longer be assassinated because there is no surprise until combat ends.
Surprise would not...
You can talk under water, but it's not very clear. With a bit of practice, this is easy to do. If you can breathe underwater, there should be no restriction. I allow my players to cast under water if they make a concentration check, but if they fail they lose the slot.
I think the druid is very strong to start with, and then needs some help at later levels. The warlock seems like it could use some love - at least some variation from EB.
