| Summary | 0002633: Elven wooden swords have same sharpness as normal wood, defeated by simple clothes | ||||
| Description | Elven wooden swords lose to fiber cloth, the weapons lack qualities such as stabbing through cloth. Cedar spear seems to work fine vs. cloth. | ||||
| Steps To Reproduce | Start an elf adventurer with sword skill and attack your home town's folk. | ||||
| Additional Information | success vs. hood: You stab The C in the head with your larch long sword, tearing the fat and bruising the muscle and bruising the skull through the rope reed fiber hood! lose vs. robe and cape: You stab The C in the upper body with your larch long sword, but the attack is deflected by The C's rope reed fiber robe! You slash The C in the right lower arm with your larch long sword, but the attack is deflected by The C's rope reed fiber robe! | ||||

Isn't that the whole point of wooden weapons? With a spear, you're concentrating the force on a single point, so it goes through easier. |

success vs. hood: You stab The C in the head with your larch long sword, tearing the fat and bruising the muscle and bruising the skull through the rope reed fiber hood! lose vs. robe and cape: You stab The C in the upper body with your larch long sword, but the attack is deflected by The C's rope reed fiber robe! You slash The C in the right lower arm with your larch long sword, but the attack is deflected by The C's rope reed fiber robe! Three data points is not enough to prove there's a major balance problem. There are all sorts of combat parameters not mentioned in the combat log, such as the squareness of the hit. |

Those were examples, not the whole combat log. I didn't want to post ten screenfuls of text into the bugtracker. Other users can try the wooden sword adventurer too to verify this. With sword's stab attacks the force should be spear-like? Do wooden baseball bats cause significant damage? Mass and strength behind the weapons should not dissipate into clothes. This is an issue that weakens the elven civilization, perhaps getting them wiped out in world history. Perhaps Toady might want to look into giving the elves special swords -- or metal. |

Those were examples, not the whole combat log. I didn't want to post ten screenfuls of text into the bugtracker. That's reasonable, but if you're trying to establish that wooden swords are consistently incapable of piercing cloth, or that there's a discrepancy between hoods and robes, we'll need you to condense those combat logs down to numbers. One common strategy is to use large numbers of combatants in the Arena -- 10 fighters with equipment A vs. 10 fighters with equipment B. With sword's stab attacks the force should be spear-like? [ITEM_WEAPON:ITEM_WEAPON_SPEAR] [ATTACK:EDGE:20:10000:stab:stabs:NO_SUB:1000] [ITEM_WEAPON:ITEM_WEAPON_SWORD_LONG] [ATTACK:EDGE:50:3000:stab:stabs:NO_SUB:1000] As you can see, the spear stab has a significantly smaller contact area (20) than the sword stab (50), which makes the spear better at piercing materials. Mass and strength behind the weapons should not dissipate into clothes. Toady commented on that problem here: http://www.bay12forums.com/smf/index.php?topic=59642.msg1377750#msg1377750 |

So I set up an arena, with 11 "skilled swordsman elves" using larch long swords and some fiber clothes (no shoes). I imported log into OpenOffice spreadsheet so can separate into sortable columns at "," and "'". And texteditor-replaced "through" into ",through". 255 instances of cloth deflecting an attack and 65 instances of damage getting through cloth. (15+2+12 strikes did damage without mentioning clothes.) CSV spreadsheet file at http://dl.dropbox.com/u/8967397/elf%20sword%20log.csv Other arena: 16 skilled spearelves with robe, cloak, pine spear. 18+20+1476 rows of damage through cloth 12 deflections by robe or cloak. CSV at http://dl.dropbox.com/u/8967397/elf_pine_spear_log.csv Yeah the sword puniness got my attention in elf sword adventurer fight. |

Interesting... looks like the stabs get through sometimes, but the slashes don't at all (except one slash through a mitten, which might be thinner or something). |
|
|
Okay, one more elf free-for-all. 16 skilled spearelves with robe, cloak, copper spear. 2x spear bash negated by cloak. 16x stabs in the head. 5x heart artery opened. 4x in the left hand. 7x in the right hand. 40x in upper body. 25x in lower body. 40x lodged firmly in the wound. 37x fractured a bone CSV log http://dl.dropbox.com/u/8967397/elf_copper_spear_log_.csv |

Reminder sent to: TomiTapio Is this bug still present in 0.34.01? |
|
|
I did a quick test in the arena, and though we haven't elven weapons there, I tested with a wooden training sword confirming that this still happens in 34.07. In fact, that unarmed man dressed in rope reed clothes won against the armed man, also wearing the same kind of clothes. |
|
|
Still in 0.40.xx Tested two battles, both groups with Adequate swordsman,adequeta dodge, adequate armor, birchen long swords, one group with plant fiber clothes in all body, the other naked. 12 x 12 The group with clothes won the two battles, one with 9 alive, other with 10 alive, so yes, plant fiber cloth makes a huge difference. In single combat, even with a legendary swordsman, I noticed the behavior of the strikes inconsistent with reality. Although the clothes should occasionally avoid slashes, the blunt strenght of the strike would still cause damage, and this is not the case. The cloth most of the time completely avoid any damage. |

I don't find a bug here, rather an emergent property of the combat and material system. This is related to bug 0005346 where obsidian swords strike as blunt weapons. 1. STRUCTURAL_ELASTICITY_WOVEN_THREAD caps the shear yield at 20000 and shear fracture at 30000 for the clothing. This means that a wooden sword can cut through an adamantine cloak. This was presumably done to prevent silk clothing from protecting against animal bites and so on. 2. Wood only has [SHEAR_YIELD:40000] and [SHEAR_FRACTURE:40000], and a low MAX_EDGE. Wood weapons are typically very light. 3. DF uses a momentum-based combat system. Due to the relative properties of the clothing to the wood, the wood has to work hard and use up a lot of momentum to penetrate the clothing. The amount of momentum available depends on attacker body size, strength, weapon weight, and many other situational variables. I recommend that modders experiment with the SHEAR_YIELD and SHEAR_FRACTURE properties, not the weapon item properties. Perhaps also use denser/heavier wood weapons to get the benefit of increased momentum? |
