Anyone know the chance of breaking out of webs?

[protopulse]

Just died to a sword spider from full HP when I was well over sword spider depth (+15 melee, +11 evasion on 400 feet). I spent all of my turns trying to break out and by the time I finally did, I was 1 hit from death. I believe it was 6 or so turns in a row of me trying to break out and failing. I had 3 strength. For a second I thought the game bugged out, because I've always broken out of webs on first or second try before with that much strength. Like what are the odds?

I could have lived probably if I quaffed an !orcish liquor. But I decided to let RNG take the reins and just watch with morbid curiosity. And turns out, RNG showed me no mercy. Even out of the web, that one sword spider was simply too good for ol' Lorod. I swear that character of mine is actually cursed. He's been dying to the most ridiculous reasons.

More STR or at least an Herb of Rage / Potion of STR will do it

[protopulse]

Yes, but that didn't answer my question...

It's an opposed d20 roll, same as most everything else in Sil. Each turn you roll a d20 and add your will score to the total. Each point of strength adds 10 effective will score, as does each source of free action (including song of freedom). To break free you need to exceed the web's DC + 1d20.

There is an up-to-date manual .pdf in the installation which comprehensibly lists all the various mechanics in the game; very useful for this sort of query.

EDIT: Actually, now I'm uncertain whether will figures into it at all. Might just be (STRx10 + #FAx10 + 1d20).

[protopulse]

Ah, okay. I actually checked the manual first and did not see it mentioned there. What is DC? Depth count? Difficulty? Are sword spider webs easier to get out of than distended spider webs?

If the formula is STRx10 + #FAx10 + 1d20, then with 3 strength, to have failed that many checks in a row, I'd imagine the odds to be quite low indeed. I must have rolled 1s and 2s each and every time on that 1d20 and the web 19s and 20s.

The difficulty is fixed at 7. Your score is your strength or -1, whatever is higher (that is, any strength lower than -1 is the same as -1.)

-10 to difficulty for each pip of free action you have.

-[banebonus] to difficulty if you have spiderbane

After that it's just d10+str vs d10+difficulty. If that comes out <=0, you break free.

(The only skill checks done with d20s are for melee vs. evasion. Everything else uses d10.)

[protopulse]

Oh, strength has much less impact than I expected. That explains it then. Thanks guys.

When you roll to escape a web, is the roll shown in the dice roll screen? Maybe it should be.

The only "roll screen" is for combat rolls. It wouldn't be that hard to make it show rolls for skill checks, but the skill_check function itself doesn't know what quantities are being checked against, so it would be trickier to inform the user of that (e.g. "7 + d10 was rolled vs 4 +d10" is easy, "player rolled 9 + d10 stealth vs monster 4 + d10 perception" would be horrid.)

I'm guessing you'd want to flag which specific rolls to show also, since there are a whole bunch happening all the time to check if the player is spotted, if they see a trap, etc.

Hmm, if I've got my numbers right it's still a decent difference:

-1: 3%     6: 45%     13: 94%
 0: 6%     7: 55%     14: 97%
 1: 10%    8: 64%     15: 99%
 2: 15%    9: 72%     16+: 100%
 3: 21%    10: 79%
 4: 28%    11: 85%
 5: 36%    12: 90%

So for 3 str & no FA you'll be out within 3 turns around 50% of the time.
2 str & no FA would be out within 3 turns 38.5% of the time.

Hmm, 3 str no FA stuck for 6 turns would be roughly 1 in 4 right? Quite possible & nasty with a fast high hitter like a spider
