Welp, imma add to the Block/Dodge discourse and say it looks great!
I would change, for clarity, in the bit for Extra Successes that those extra successes specifically apply for Blocking and maybe add a sentence or two for extra successes for attacking in the attack section similar to stunts in Alien. Seems including both under Blocking has caused some confusion.
So, for everyone else; blocking does not burn your action for nothing. Blocking is only against other humanoids, Dodge is what you use against humanoids or creatures to get a much higher chance of avoiding damage. A one-action combat economy also makes rounds fly by much faster than before in YZE games (or games that shall not be named where one round can take 10 minutes), this i have learned from playing DB for a few months now. Nobody is going to be bored with these combats or feel like their action is wasted when just one hit can be instant death.
Anyway, Blocking goes like this;
1, Attacker in close combat attacks PC, PC declares block before attacker rolls. Results in either;
2a, Attacker rolls 1 or more successes, PC rolls 1 or more successes, deal with as per rules.
2b, Attacker rolls 1 or more successes, PC rolls 0 successes. PC takes damage, deal with as per rules.
2c, Attacker rolls no successes, PC rolls 1 or more successes, PC can attempt any of the three listed effects which essentially gives them an action out of turn order.
Also this kind of action economy heavily favors working together as a group, which is a Coriolis staple. I think thats pretty neat
Oh and the much nicer critical damage table is now too nice!
