Post Alternative to the SIEGE system
Over on DF is a thread where folks are discussing a way to replace SIEGE with something similar. I think that an awesome idea from that thread is simply to make use of the 5E "Advantage" mechanic, e.g. instead of having a 18/12 type difficulty roll you could keep all checks at 18 difficulty and then call for Advantage in any class skill.

Folks who have tinkered with the mathematics behind Advantage/Disadvantage claim that it's roughly +5/-5 so that's not so far from the SIEGE +6, plus rolling 2d20 and keeping the best one is kind of neat.

Pretty intuitive as well, IMO. Of course, its not absolute like a +6 is but something I'd give a try in a home game.

I'm working on SIEGE with skills... I also heear there are 15-10 systems too., I think in the CKG. Advantage and disadvantage can be additive within SIEGE. I thought SIEGE was mainly the idea that "anything is possible, just roll it" with some logic behind "easy for you because your class does that and you're extra good at it" vs "you better roll a 20 because your class does not do that and you are weak in that area too."

I looked at the 15, +3/-3 style and it worked for some pathfinder players. But I don't know, the 18/12 feels more 'AD&D' or nostalgic to me.

The only thing I would change is spells & spell like effects CB was 18/12 +spell level & wizard mod or 1/2 monster HD (round up) to make some survivability vs. magic at higher levels. Other SIEGE checks were straight up PC level vs. monster HD.

I like the advantage system from 5e but would use it for action points vs. normal SIEGE checks. I see a 12 CB being much easier to survive vs. a 2nd d20 roll.

But hey, opinions...

The claim that advantage gives a rough +5 is a bit misleading. It's merely a statement that rolling a 15 has roughly a 50% chance when using advantage, same as rolling a 10 without advantage has a 50% chance. But that breaks down quickly as you move away from 10.

With advantage, you can't ever roll above 20. Further, the odds of rolling a 20 when you have advantage is 9.75%. The odds of rolling a 20 with d20+6 is 35%. If i need a 20, i definitely prefer the +6. Heck, even a +1 without advantage gives better odds of getting a 20 than advantage.

The main advantage to advantage (heh) is that it protects against really bad rolls.

So would that mean there is no "advantage" to using "advantage"? :lol:

I'm working on what i call siege light. I use modern attribute bonuses (12+1, 14+2, etc), but only allow the pc to add 1/2 their level to rolls. I've also removed bth values and replaced it with the siege light roll.
