Lloyd Dupont Posted November 25, 2021 Share Posted November 25, 2021 (edited) After trying a bit of both I realised there are subtle incompatibilities between the 2 rulesets. For example Mythras damage tables work much better with hit location hit point, but using BRP damage tables with location hit point was not a very good experience, at least for me. Also luck in Mythras is much better, a few point with big impact. Not 60 points that one could milk endlessly to never miss their 90% skill. Also, after brainstorming about magic for a while I finally realised that Mythras version of Classic Fantasy (not the earlier BRP version) is exactly what I was looking for all along!! 😅 The class concept there is also fantastic and very open... Gotta create many original classes in my master of Orion setting, like merchant Prince or Diva! Now, before I swing back into the Mythras camp, there are 2 issues that I had with Mythras mechanics I want to brainstorm a bit with you guys. First, and it pains me to say because it looks good on paper, is a basic combat rule that is used successfully by many, but action points was a bit of a slog with my group.. Particularly with bonus defensive action from CF, we got color tokens on the table and... It was not smooth. I could go for BRP combat flow (1 action any number of reaction with cumulative malus) which was a great success. But fighters would be losing out in offensive potential here.. Never mind, got an idea, gotta introduce multi attack for chosen monsters and fighters.... The second issue is more tricky. It's about saves. In BRP one use the resistance table, whereas in Mythras one do opposed skill check. I don't mind a bit of skill here, but I prefer the resistance table. But in Mythras POW almost never change, so the resistance table will be endlessly frustrating for the player. And I also like characteristics that do not change much... Basically I'm conflicted here and will take any ideas! 😏 Edited November 25, 2021 by Lloyd Dupont Quote Link to comment Share on other sites More sharing options...

They can then use them for attack/defence other things as per the RAW, but you're simply limiting the amount of actions. Mythras has this as an optional rule in RAW already.

Basically I'm conflicted here and will take any ideas! 😏 Mythras replaces Characteristic opposition on the Resistance Table with Opposed Skills. If you prefer the Resistance Table for opposed resolution, you could continue to use things like Willpower, Endurance and Evade, but perhaps divide them by 5 to give you a number in the range of 1-20, so that they can be compared against Characteristics at roughly the same scale. You can also separate them from the Standard Skill list and give their own grouping called 'Saves' or 'Resistances'. Retaining the % value allows for them to be increased as per Mythras RAW, but the smaller range from dividing by 5 keeps them distinct and usable with the BRP core method. So for example, a character might have: Endurance 50% (10) Evade 60% (12) Willpower 36% (8) You can take the same approach with any skill if you want to use the Resistance Table: Perception vs Stealth; Acrobatics vs Combat Style, and so on - although the Opposed Skill rules aren't that difficult to grasp and don't require any table cross-referencing, or dividing skills down to get a lower range. 1 1 Quote The Design Mechanism: Publishers of Mythras Link to comment Share on other sites More sharing options...

Personally I prefer RQ3 game mechanics over most other versions of BRP or related games, yet I'll port something over from those other games if it fits the campaign. Action points and multiple actions are one of the things I like least about Mythas, as it makes a 1 point diffference in DEX too important for my tastes. I'd probably use RQ3 (or RQ2) strike ranks instead. And if you are conflicted between resilience, persisistence, etc. and the resistance table, you could always takes a page out of FASA Star Trek and average 1/5th the skill % with the characteristic on the table. That way someone with, say Resilience 70% and CON 10 would end up using a 12 on the resistance table.

IIRC, skill opposition in Mythras results in a stale when both characters fail their roll. I'd let the highest roll win in such a case. 1 Quote Link to comment Share on other sites More sharing options...

Never mind, got an idea, gotta introduce multi attack for chosen monsters and fighters.... An option could be that everyone has one attack and one parry per turn (or you prefer, like Loz says, two actions that can be attacks or parries). If you like the uncertainty or like to give an edge to higher skilled fighter, you could use two special effects only available on defensive rolls. Defensive maneuvering would allow for another defense against the same or another opponent. Create opening would allow for an immediate additional attack against the same opponent or another that is adjacent. Because they can only be used on defensive rolls, it avoids the potential infinite number of attacks. Because they are special effect, choosing an extra defense or an extra attack becomes a tactical choice. Will you choose one of them over another effect? I see that as a feature. Note that you could choose defensive maneuvering and just waste it because none of the other opponents attack you. It goes with playing defensive. Again I see that as a feature.

Lloyd Dupont Posted November 25, 2021 Author Share Posted November 25, 2021 Yea... I made my own simplified table of effect (ahem or less simplified as it grow), it already has "riposte" on defender advantage (but it's a reaction, might incur cumulative -30% as per BRP rules), and was thinking to add disarm and..... grab weapon (might do a DEXvsDEX roll with malus depending on weapon, i.e. swords are harder to grab than spears) Quote Link to comment Share on other sites More sharing options...

Every skill was 1/5th what it would be in BRP and then handled with an opposed roll. SO if one character had Rapier 15 (75%) and his opponent had Rapier 12 (60%) you'd cross reference 15 vs. 12 on the resistance table to get a 65% chance of success.

I gave everything a point cost to buy with the difference. So ripostes, disarms, drive backs, trips, increased damage, etc. could all be chosen if the character had enough of an advantage to pay for it. Multiple specials could also be bought if the character had points left over. I even added a feint maneuver where a player could bank excess advantage points over to the next round so as to save up for a better special effect. The latter was risky though since the points would be lost if the character lost the next opposed roll. The nice thing about using the dice was that I didn't need to track special and crtical chances, and could do everything with one opposed roll.

On the resistance table a 5 point difference turns a 50-50% chance into a 75-25%. So one level per 5 points would seem to be the closest to the resistance table. 1 minute ago, Lloyd Dupont said: This is a case where bonus/malus is the only viable solution. Perhaps something like +/-20% per 8POW difference? I think that would make POW a non-factor. A sixteen point difference, about the max you'd see in play for normal humans, would only be a +/-40% modifier. In normal BRP such a difference would be an automatic success. Since the modifier isn't reflexive (doesn't apply to both parties) like the resistance table, I'd suggest a simple +10% per point of difference. Or if you make it reflexive then +5%/-5% would keep the feel and effect of the resistance table. 1 Quote Chaos stalks my world, but she's a big girl and can take of herself.

I brought the game up because your wish to mix the resistance table with opposed skill scores is pretty much what Pendragon does. Unlike most other BRP games it uses a D20 instead of D100, and handles most tasks with opposed rolls. For example, in combat both combatants would roll their skill and whoever won the opposed roll would roll damage against the loser.

Bushido, Aftermath and Daredevils, for instance, published by FGU and written by Bob Charette, employed the same mechanic quite a while before Pendragon. All three are very crunchy games, but they also have a lot of internal consistency and while the way the mechanics are presented is quite daunting, at its heart the system is pretty simple. For opposed skills, you generate an Effect Number (which can have multiple uses and is a brilliant mechanic). The Effect Number is the difference between your Base Chance of Success on a d20, and what you actually roll. So if you have a BCS of 19 and roll a 1, then you generate an Effect Number of 18. If you have to have opposed skill rolls, using Effect Numbers as the comparison is an elegant way of determining the winner. They're worth checking out, All three are still available from FGU.

You make me think about it again... (plus it's quite familiar to the D&D crowd) One thing though I am a bit curious about. What about: So each round someone damage an opponent? Sort of. The winner rolls damage on the loser, but that damage is reduced by armor and possibly shield. Depending on how much damage someone does, and how much armor the opponent has to soak it, it is possible to have a fight where no one gets hurt. For instance, a typical character does 4d6 damage, and a knight in reinforced mail has 12 points of protection, plus another 6 from his shield, if he makes his roll. So on average the knight would take no damage on the rounds that he got a partial success (that is rolled under his skill but was beaten), and a minor (2 point) injury when he failed. A serious injury would probably require a critical success, which does double damage. 10 hours ago, Lloyd Dupont said: Not that it is desirable or happens much in BRP but.. is it possible to have a drawn out duel which is much like a stalemate? Yes, if a few ways. The first and most likely is to have a tie. On a tie you get a stalemate for the round. Ties a a bit more common in Pendragon, due to the way it handles crticals and skills over 20. Basically any roll of your modified skill exactly is a critical success, and is treated as a roll of 20. If your modified skills is over 20 then you add the points over 20 to your die roll. So if you have two highly skilled combatants you can get a fight that can last awhile. In fact there is even a special rule to deal with such a long term standoff. Another way to get a stalemate is if both combatant's fail their skill roll. Yet another way is when someone is fighting defensively. Doing so grants then a +10 bonus to their skill, but they do not get to roll damage if they win. 1 Quote Chaos stalks my world, but she's a big girl and can take of herself.

Yes, but the mechanic they use isn't the same as Pendragon. As you point out they generate an effect number (how much you make your roll by) but Pendragon uses what you roll as the result. So in Pendragon someone with skill 19 who rolls a 1 gets a result of 1 not an effect of 19. And since the actual number rolled in Pendragon only matters to determine who wins and if someone rolled a crtical, it isn't as crunchy as the Charrette-Hume method. I think Tunnels & Trolls was the first system to use opposed "Attack" rolls as the result. Hmm, funny how all this stuff is interconnected. Bob Chareette also wrote RQ3's Land of the Ninja, and Ken St. Andre co-wrote Strombringer, Oh, and you wrote some Hawkmoon and Elric stuff.
