In Dragon Age every time a player scores a double he can add some special effects to his action, this seemed to tie-in quite well with the mechanics for great and extraordinary success, so I decided to gave it a shot. and this is what I came up with.
Combat Stunts in The One Ring
(this rule replaces both Called Shot and the extra damage from great or extraordinary success)
When a character rolls a great or extraordinary success on an attack he can choose to add an effect from the following table. It's possible to trade one extraordinary effect for two great effects, but each effect can be choosen only once, unless otherwise specified.
When a hero rolls an "Eye" or an Adversary rolls a "Gandalf" this provides their opponent one free level of success on the Stunt table.
Specific creatures or weapon might be able to perform other stunts depending on thier abilities and weapons (e.g. Orcs' poison arrows).
Great success Stunts
- Cleave: you can hit two opponents with a single attack, if your original roll is high enough, you cna decide how to split damage between them (exception: you can apply other effects -- likepiercing blow or break shield -- only on one target)
- Higher ground: you gain one Die of Combat Advantage immediately
- Into the fray you can perform a combat task immediately, but this task can't benefit from great or extraordinary success (exception: you can't perform Skirmish after performing this task)
- Mighty Blow (can be chosen twice): add your Damage rating to the total damage
- Skirmish: you can immediately move one stance forward or backward and this sets your TN until the next round (exception: you can't move Rearward unless the usual conditions are met)
- Break shield: you break your opponent shield or knock it out of his graps (special: axes and mattock can perform this as a Great success stunt)
- Disarm: you knock your opponent weapon out of his graps (special: swords can perform this as a Great success stunt)
- Knockback: you knock your opponent out of balance, denying him the possibility to execute his next attack (special: spears can perform this as a Great success stunt)
- Pierce Armor: you inflict a piercing blow even if you didn't score an edge, but your Injury rating is -2 (special: bows can perform this as a Great success stunt)
On his way to the Carrock Aric "the Red" is ambushed by two Snagga trackers, after the opening volleys the Beorning grasps his great spear and attacks.
Being outnumbered Aric stays in defensive stance and rolls his spear attack, unfortunatly his skill isn't good enough to allow him to land a hit.
The Snagas counterattack with their knives, both miss, but one rolls a "Gandalf", giving Aric an opening and a single success to use on the Stunt table the next round.
Feeling a bit emboldened Aric switches to open stance and rolls, this time he scores a great success, which gives him two great successes to spend on Stunt. He chooses to cleave through both of his opponents and knock one of them back (usually an extraordinary stunt, but Aric uses a spear). He splits the 9 damage between the two as evenly as possible and deny the one of the Snagas the chance to counterattack.
Overall I think this table makes the combat potentially more cinematic and unpredictable, I'm not sure this will fit with the overall tone of the game, but I think it's worth the shot. What do you think?
