	"Fl<EFBFBD>ssigkeit verdampft ist. Diesen Brei stelle man <20>ber Nacht raus. "
	"Am n<>chsten Morgen presse man den Brei aus. Die so gewonnene "
	"Fl<EFBFBD>ssigkeit, Goliathwasser genannt, verleiht bis zu zehn M<>nnern die "
	"Tragkraft eines Pferdes.",

	"Das 'Wasser des Lebens' ist in der Lage, aus gef<65>llten Baumst<73>mmen "
	"wieder lebende B<>ume zu machen. Dazu wird ein knotiger Saugwurz zusammen mit einem "
	"Elfenlieb erw<72>rmt, so da<64> man gerade noch den Finger reinhalten "
	"kann. Dies gie<69>e man in ein Gef<65><66> und lasse es langsam abk<62>hlen. "
	"Der Extrakt reicht f<>r 10 Holzst<73>mme.",

	/* Stufe 2: */
	"Man lasse einen W<>rzigen Wagemut drei Stunden lang in einem "
	"Liter Wasser k<>cheln."
	"Dann gebe man eine geriebene Alraune dazu und bestreue "
	"das ganze mit bei Vollmond geerntetem Spaltwachs. Nun lasse man den "
	"Sud drei Tage an einem dunklen und warmen Ort ziehen und seie dann die "
	"Fl<EFBFBD>ssigkeit ab. Dieser Schaffenstrunk erh<72>ht die Kraft und Ausdauer von "
	"zehn M<>nnern, so da<64> sie doppelt soviel schaffen k<>nnen wie sonst.",

	"Ist man nach einem einem harten Kampf schwer verwundet, ist es ratsam, "
	"etwas Wundsalbe parat zu haben. Streicht man diese magische Paste auf "
	"die Wunden, schlie<69>en sich diese augenblicklich. F<>r die Herstellung "
	"ben<EFBFBD>tigt der Alchemist nebst einem Blauen "
	"Baumringel einen W<>rzigen Wagemut und einen Wei<65>en W<>terich. Eine solche Portion "
	"heilt bis zu 400 Lebenspunkte.",

	"Zu den gef<65>hrlichsten und geheimsten Wissen der Alchemisten z<>hlt die "
	"Kenntnis um diesen Trank. Den finstersten H<>llen entrissen, erm<72>glicht "
	"die Kenntnis dieser Formel die Herstellung eines Elixiers, welches "
	"D<EFBFBD>monen als Nahrung dient. Von normalen Lebewesen eingenommen, f<>hrt "
	"es zu schnellem Tod und ewigen Nichtleben. Die Herstellung ben<65>tigt "
	"nebst Fjordwuchs, etwas H<>hlenglimm und einem Blauen Baumringel auch einen Bauern aus der Region, "
	"welcher in einem tagelangen blutigen Ritual get<65>tet wird. Ein Fl<46>schchen "
	"des Tranks kann den Hunger von 100 D<>monen f<>r eine Woche stillen.",

	/* Stufe 3: */
	"F<EFBFBD>r das Gehirnschmalz verr<72>hre man den Saft eines Wasserfinders mit "
	"recht viel geriebenem Windbeutel und ein wenig Gurgelkraut. Dies lasse "
	"man kurz aufwallen. Wenn die Fl<46>ssigkeit nur noch handwarm ist, gebe "
	"man etwas Steinbei<65>er dazu. Das ganze mu<6D> "
	"genau siebenmal rechtsherum und siebenmal linksherum mit einem gro<72>en "
	"L<EFBFBD>ffel ger<65>hrt werden. Wenn keine Bewegung mehr zu erkennen ist, "
	"f<EFBFBD>lle man den Saft ab. Der Saft erh<72>ht die Lernf<6E>higkeit von bis zu "
	"zehn Personen um zehn Tage.",

	"Das Dumpfbackenbrot ist eine sehr gemeine Sache, macht es doch jeden "
	"Lernerfolg zunichte oder l<><6C>t einen gar Dinge vergessen! F<>r zehn "
	"Portionen verknete man einen geriebenen Fjordwuchs, einen zersto<74>enes "
	"Eulenauge und einen kleingeschnittenen Gr<47>nen Spinnerich zu "
	"einem geschmeidigen Teig. Diesen backe man eine Stunde lang bei guter Hitze "
   "und bestreiche das Ergebnis mit etwas H<>hlenglimm. "
	"Wer dieses Brot gegessen hat, kann eine Woche lang "
	"nichts lernen, und so er nichts zu lernen versucht, wird er gar "
	"eine Woche seiner besten F<>higkeit vergessen.",

	"Nestw<EFBFBD>rme erlaubt es einem Insekt, im Winter au<61>erhalb von W<>sten neue "
	"Rekruten anzuwerben. "
	"Zur Zubereitung nimmt der ge<67>bte Alchemist einen Kakteenschwitz, "
	"vermischt ihn mit einer Portion Spaltwachs, die in einer sternklaren "
	"Nacht gesammelt wurde, gibt zur Vertreibung des Winters einige "
	"Bl<EFBFBD>tenbl<EFBFBD>tter der Eisblume in den Sud, und r<>hrt alles mit einem gr<67>nen "
	"Spinnerich bis es eine "
	"violette Farbe annimmt. Ein Trank reicht eine Woche lang f<>r eine "
	"ganze Region. ",

	"F<EFBFBD>r das Pferdegl<67>ck zerhacke man einen Kakteenschwitz, "
	"einen blauen Baumringel und etwas knotigen Saugwurz und koche das "
	"ganze mit einem Eimer Wasser auf. Dann f<>ge man etwas Sandf<64>ule dazu "
	"und lasse diesen Sud drei Tage lang ziehen. Letztlich gebe man es "
	"den Pferden zu trinken, auf da<64> sie sich doppelt so schnell vermehren.",

	"Will man seine Krieger zu H<>chstleistungen antreiben, sei das "
	"Berserkerblut empfohlen. Um es herzustellen, braucht man einen "
	"Wei<EFBFBD>en W<>terich, etwas Flachwurz, "
	"Sandf<EFBFBD>ule und eine Alraune. Alle Zutaten m<>ssen "
	"m<EFBFBD>glichst klein geschnitten und anschlie<69>end zwei Stunden lang gekocht "
	"werden. Den abgek<65>hlten Brei gebe man in ein Tuch und presse ihn aus. "
	"Der so gewonnene Saft reicht aus, um zehn K<>mpfer besser angreifen zu "
	"lassen.",

	/* Stufe 4 */
	"Das Bauernlieb bet<65>rt Mann und Frau gleichwohl und l<><6C>t in ihnen "
	"den Wunsch nach Kindern anwachsen. F<>r eine gro<72>e Portion h<>hle "
	"man eine Alraune aus, gebe kleingehackten Blasenmorchel, Elfenlieb "
	"und Schneekristall dazu, streue ein wenig geriebenen Steinbei<65>er dar<61>ber und lasse dieses zwanzig "
	"Stunden lang auf kleiner Flamme kochen. Bis zu 1000 Bauern vermag "
	"der Trank das Gl<47>ck von Zwillinge zu bescheren.",

	/* Stufe 1, Trank der Wahrheit */
	"Dieses wirkungsvolle einfache Gebr<62>u sch<63>rft die Sinne des Trinkers "
	"derart, da<64> er in der Lage ist, eine Woche lang auch die komplexesten "
	"Illusionen zu durchschauen. Zur Herstellung ben<65>tigt ein Alchemist "
	"einen Flachwurz und einen Fjordwuchs.",

	"Eines der seltensten und wertvollsten alchemistischen Elixiere, verleiht "
	"dieser Trank dem Anwender f<>r einige Wochen die Kraft eines Drachen. "
	"Der Trank erh<72>ht die Lebensenergie von maximal zehn "
	"Personen auf das f<>nffache. Die Wirkung ist direkt nach der Einnahme "
	"am st<73>rksten und klingt danach langsam ab. Zur Herstellung "
	"ben<EFBFBD>tigt der Alchemist ein Elfenlieb, einen Windbeutel, "
	"ein St<53>ck Wasserfinder und einen Gr<47>nen Spinnerich. "
	"<EFBFBD>ber dieses Mischung streue er schlie<69>lich einen zerriebenen Blasenmorchel "
	"und r<>hre dieses Pulver unter etwas Drachenblut.",

	"F<EFBFBD>r einen Heiltrank nehme man die Schale eines Windbeutels "
	"und etwas Gurgelkraut, r<>hre eine "
	"kleingehacktes Elfenlieb dazu und bestreue alles mit den "
	"Bl<EFBFBD>ten einer Eisblume. Dies mu<6D> vier Tage lang g<>ren, wobei man am "
	"zweiten Tag einen Spaltwachs dazutun mu<6D>. Dann ziehe man vorsichtig "
	"den oben schwimmenden Saft ab. Ein solcher Trank gibt vier M<>nnern "
	"(oder einem Mann vier mal) im Kampf eine Chance von 50%, sonst t<>dliche "
	"Wunden zu <20>berleben. Der Trank wird von ihnen automatisch bei "
	"Verletzung angewandt.",
