Update5より導入の新Feat、Trapmakingについて、HarborのFree Agent Vendorで販売されているガイドのテキスト起こしです。翻訳は面倒なのでパスそのうちレシピまとめがどっかに載るでしょう。とりあえずOld Sullyさんが現役時代、ばばん連中とどれだけ仲が悪かったのかが忍ばれるガイドとなっております。
Old Sully's Guide to Practical Trapmaking, Part One: Granades
Trapmaking. Obsession of those accursed kobolds and best way to keep loot safe.
While there's nothing funner than seeing your barbarian charge off ahead despite your warnings and get blown to bits by a trap you would have disarmed had he waited just FIVE MORE SECONDS, this guild isn't about that. I'm going to assume you already know how to find and disarm hostile traps. Instead, I'll teach you how to take the parts those kobolds generously left lying around the dungeons (if you get them before THAT BLASTED BARBARIAN SET THEM OFF) and do something useful with them.
Scavenge parts from traps you disarm. If you're mechanically focused, you'll probably have a better chance of finding the parts you need. Look for the things that make the barbarian go boom --vials of acid, flasks of flaming goo - that sort of thing. Some purely mechanical traps will just you gears, spikes, and the like - those can be useful too, but we'll worry about that later, when we get to placed traps.
The simplest thing to do is to combine, say, ten scavenged fire parts with ten crude vials at a device workstation.
That'll create ten (pretty weak) throwable fire flasks. Not too great, but a good thing to practice. Capshaw's boys will generally have some of the vials lying around.
You can replace the fire parts with the guts of most other traps to make things that blow up barbarians using different flavors.
Now, to properly blow up a barbarian, or an enemy for that matter, you'll want stronger stuff. Try taking a pile of those parts (25 or so?) and combining them in that device workstation with some siberys dragonshard fragments to act as concentrating foci (let's say 10 of them) and ten of those cheapo crude vials. Careful not blow yourself up. There, you should have a few (still pretty weak) intermediate grenades.
The next tier up will probably require making friends with a wizard, or at least an auctioneer. Take fifty fire trap parts, a weak trapped fire elemental soul gem, fifty siberys dragonshard fragments, and you'll have to move up to ten simple vials. (The gunk on the inside of the crude ones will mess things up, and that's the last thing you want when dealing with explosive.) Putting in seventy five trap parts, a hundred siberys fragments, and a normal trapped elemental soul gem into simple vials will also work, resulting in a more powerful end result.
The most powerful recipe I know is one hundred trap parts, two hundred fifty siberys fragments, and a strong soul gem in unadorned vials.
These last few recipes work great on elemental damage grenades, but I haven't figured out what soul gem to use to make force and sonic traps yet.
Old Sully's Guide to Practical Trapmaking, Part Two: Mines
Now I know some of you think it's folly to carry around portable containers of explosives everywhere you go, but when you have Improved Evasion - who cares? It's not like an exploding trap in my backpack will run my day.
Remember those mechanical components we mentioned in the first part of my primer? Take twenty-five of those, and link them together at that device workstation. You should be able to put a few simple noise making devices together pretty easily. These things have a short delay on them, and then start making a racket - great for a distraction when there's a guarded lever that you want to sneak to. Lots of monsters have cotton in their ears, don't put it too far away from them or they might not even notice.
You can use the same techniques as you used to making grenades create actual portable explosive traps of the various elements - just swap out the vials for a handful of mechanical parts and combine as usual with your assorted other ingredients.
The difficulty to resist your trap is directly linked to how good your mechanical skills are - specifically, how high your skill is at disabling devices at the time you set the thing. If you spend extra effort on learning the way of the mechanic, your traps will be even more difficult to resist.
Like the grenades, siberys dragonshard fragments can be used as concentrating foci and more powerful trap can be created using soul gems from appropriate critters - Experiment away!
Old Sully's Guide to Practical Trapmaking, Part Three: Spell Traps
So far I've written about damaging effects, but sometimes it's nice to have some arcane tricks up your sleeve. It's possible to create a placed trap that fires off effects from scrolls on all nearby creatures when triggered.
You'll need some magical trap parts, some mechanical parts, and some arcane scrolls. Only first to third level scrolls will work, and only spells that debilitate opponents - Cause Fear, Sleep, Glitterdust, Web, Halt Undead, that sort of thing.
Oh, and Grease. Everyone loves Grease.
For first level spells, ten magical parts, ten mechanical parts, and ten scrolls will create five spell traps. Higher level spell traps require more magical parts. Since these are cast from scrolls, the magic's not that strong, but a well placed web, blindness, or hold person trap can give you the edge you need to win a battle.
A well place Grease trap probably won't win the battle, but it'll certainly be entertaining. Good luck!
