>>95955259So here's an example.
Ayen, 4th Lvl Fighter with an Elven Pole-Axe+1: +3A, +1C, +3F at long, +1A, -1C, +1F at short. We'll say this fight is at long range to keep it simple.
VS
6HD Troll with a big wooden club: +5, +1C, -3F
>Round 1Troll declares Assault, Ayen declares Counter.
Troll rolls 1d20 + 6 (HD) + 5 (Weapon). He gets 18
Ayen rolls 1d20 + 4 (Fighter Level) + 3 (Weapon) + 5 (Counter beats Assault). She gets 16.
Trollwins with MoS of 2
Both roll damage, troll puts all his MoS into increasing damage.
>Round 2Troll (more cunning that it seems) declares Feint, Ayen declares Counter.
Troll rolls 1d20 + 6 (HD) + 5 (Weapon) + 5 (Feint beats Counter). He gets 26
Ayen rolls 1d20 + 4 (Fighter Level) + 3 (Weapon). She gets 27 (I actually did roll an epic natty 20 as I'm writing and demoing this)
Ayen wins with MoS of 1
Both roll damage, Ayen puts all her MoS into reducing damage.
and so on until the rest of the party help her out.
I don't know about class HP and weapon Damage values. That's the boring numbers part that playtesting will reveal. Come up with some values and see how it goes.
D20vsD20 was just an example since it's the D&D die, but anything could work. Maybe 2d6 or 3d6 would be more appropriate...
Maybe strength adds to Damage and Assault, Dexterity adds to Feint, the higher of Intelligence or Wisdom adds to Counter?
As an aside, you could have an optional fourth Intent called "Defend" where it gives you a +10, +15, +5 against Assault, Counter, and Feint respectively, but affords you no damage roll. It's an option for holding out where you need to survive for a long time rather than kill the enemy. Like holding a doorway so your Magic User can cast that
