I'm new in Fate, and I'm amazed by the game style and mechanics.
Nevertheless, reading the manual, I think I've found 3 mechanical incongruences.
Speaking about the Four Actions and their outcomes, in the Create an Advantage section, you can read that:
If you’re using create an advantage on an existing aspect…
- When you fail, you give a free invoke on that aspect to someone else instead. That could be your opponent in a conflict, or any character who could tangibly benefit to your detriment.
- When you tie or succeed, you place a free invocation on the aspect.
- When you succeed with style, you place two free invocations on the aspect.
But reading the Defense section, you'll find:
- When you fail at a defense, you suffer the consequences of whatever you were trying to prevent. You might take a hit or have an advantage created on you.
- When you tie a defense, you grant your opponent a boost.
- When you succeed at a defense, you successfully avoid the attack or the attempt to gain an advantage on you.
- When you succeed with style at a defense, it works like a normal success, but you also gain a boost as you turn the tables momentarily.
First incongruence: if A tries to create an advantage on an existing aspect of B, and B manage to tie the defense, then from the Create an Advantage section of the manual A manages to place a free invocation on the aspect, but from the Defense point of view, well, A will not have a free invocation on the aspect but a boost.
Second incongruence: if B (defense) succeeds, it will avoid the attempt, but seen from the perspective of A (Create an Advantage - fail), B will have a free invoke on that aspect.
Third incongruence: if B (defense) succeeds with style, then it will be a success + boost for B. But again, seen from the perspective of A (Create an Advantage - fail) B will have a free invoke on that aspect.
So, these are real incongruences in the manual of Fate Core or am I missing something?
