2. Yea, but notice that there's one second roll to determine which constellation, that was my doubt (and for the second roll the -1 could be useful)
5. Humm, understand, but I think you explained wrong, am I right? If I roll 1-3 I need only 1 success to beat, 4-5, 2 successes to beat (and not 5 as you said) and on a roll 6 need 3 successes to beat, right? But how am I supposed to know that? That isn't in the rules, there're just numbers there and nothing explained.
6. This means I have many more chances to win with this tribe I guess?
Looking forward for next updates! Good work!
