#taking an action initiating the grapple
Just like how it works currently: you just tag the aspect then perform the grapple/block.
The difference with this method is you can do more than just block (since that's done automatically), you can do a maneuver or attack etc...
So it's part of your action, but it doesn't use up your action.
That's more powerful than what's in canon. Might be abusable.
Although, now I'm seeing how this method can be abused. If you have a high Might+Supernatural STR, you could tag an aspect and set up an Epic block on a wizard without even having to roll dice. Granted, this block doesn't impede/block the wizards ability to blast you...so maybe that's the balancing factor...dunno.
I don't think that's too terrible. You can do something similar in canon, after all.
#Free tags:
Anyone NOT in the grapple, I'd think? I'd be happy to do away with this, but I just figured there's lot of things that people outside the grapple could do to people who are stuck in a grapple. I just figured it'd be easiest to model the "disadvantage" of being locked in a grapple is by using an aspect.
I don't think that's a good idea. Tags go away when used, so if opposing characters both have access to one then it creates a perverse incentive for each character to use the tags before their opponents can.
I suggest making the Aspects non-taggable. People could still Invoke them, of course.
