Hey, absolutely love the game and I'm really excited about bards but something in the article has me a bit concerned
"On top of that Cutting Words has been buffed in Solasta: the targeted enemy decreases all its ability checks, attack and damage rolls by the value of the Bardic Inspiration die until the start of the Bard's next turn. This was done to avoid having pop-ups interrupting the game every time the enemy did something during their turn."
First up I absolutely accept that as written in SRD it would be too disruptive. And even if it was limited to hits/successes with a degree of success in range of the inspiration dice, similar to how shield is implemented it's probably still too disruptive.
But this is actually a fairly major nerf to the ability. The fundamental issue is that cutting words can be applied to every enemy you can see at the time they hit as opposed to a single enemy and the Bard player knows the value of the role and probably what is needed for a hit or success when they choose to use it, as player AC isn't hidden information like enemy AC sometimes is. In contrast targeting a single enemy even affecting all of their roles, thats a lot fewer roles and there's a good chance none of them could even be changed by the inspiration dice. With a d6 if it's even possible for the full range of 1-6 to be useful it's a 30% chance on any given role it even can make a difference, 9% with disadvantage. How many roles is the enemy making? That goes up to 50% (25% disadvantage) at d10 inspiration but then the full range being possible is an even bigger issue. For example if the player has an AC of 20 an enemy attack with a +5 bonus, a role of 20 is a hit regardless so the highest their attack can be is 24. Only a role of 15-19 could be changed by cutting words. So 25% in this example regardless of whether the inspiration dice is d6 or d10.
Not only do you have to be aware of the enemy on your turn and foresee they are the threat, their dice have to line up just right for the ability to even have a chance of doing anything.
My suggestion is that the ability works as written above but targeting an enemy doesn't cost an inspiration or reaction until a viable role occurs and then both are spent. I think this is still a major nerf (eg. targeted enemy misses regardless of the cutting words but another enemy hits is not an unlikely sequence of events) but it removes needing to forsee the target's dice roll to not waste the inspiration which makes it more fair.
