I received an invite to participate in a level 40 moon boss and was really happy to get it. I'm just over lvl 500 and am afraid I can't get min dmg in a reasonable amt of time. I didn't want to join and take a spot from someone if I can't finish, so clicking with 5 stam and doing the math only to find out I can't do it isn't the thing to do. I want to respect my fellow mobbies by not wasting a space and I also don't want to embarass myself by not being able to finish. I know, for example, how much stam it takes me for a lv 22 Madrid boss. Is there a rule of thumb for me to estimate how much I need for moon, accounting for the fact that the Moon boss is a lot higher level and in a much higher location?
