In my session last night, one of the characters was pretty badly hurt (no crits, just a lot of wound). They made their way to a city on the planet they are on, and were looking for a medical facility. I figured this city was big enough that they would have the equivalent of a medical clinic, with medical droids and bacta tanks. One wanted to spend the night in the bacta tank, and it sounded reasonable for me. What I was NOT sure about was what a fair cost would be to "use" the bacta tank? They cost 4000cr to buy, but I thought that "using" one for the night could be cheaper. I decided on 20cr. (This assumes about 200 uses to "break even" with its cost, and that seemed OK to me in my head).
Does this seem like a reasonable price? Did I overcharge/undercharge them? I didn't want to strip them of all their remaining credits, but wanted them to come into the next encounter not on the verge of death, either
