A quick scenario that asks a question..
Cask O' Brandy
"Help us" cried Brother Tucker as he approached your group of adventurers, "We've got to get our erm.. cargo to next town over for the festival, but are worried about ahh.. bandits!" You all shout, "Of course!"
Group of 3rd level PCs, Human Fighter, Gnome Cleric, 1/2 Elf Wizard, and a Hobbit Thief, with a standard fantasy class stat mix.
You all are walking next to a cart hauling a large cask of brandy pulled by a mule with a teamster. SUPRISE! From behind a large boulder a huge net is flung.. ouch, a great toss, the whole group is caught. With a whoop an Ogre jumps down and stuffs you all in a large sack and proceeds to smack you against the boulder until there's no more movement.
The four of you wake up, bruised but okay, in a dark locked cupboard to the sound of snoring. Through a crack you can see the ogre with it's feet up on the cask, and its head thrown back snoring loudly with assorted gnawed bones around him. You see your gear on a nitch over his head. After the thief jimmies the crude lock open, you make it into the room, where you see the Ogre's belt and gear against the wall. The large weapons include a Great Club (for smushing big stuff), a Club (for smushing little stuff), and two daggers (for eating smushed stuff). You also see against the wall in the corner, the remains of two swatted pixies, one with a tiny Greatsword, the other with a tiny Longsword, each also has a tiny dagger.
Listen check reveals scratching sounds coming closer... hope you've got your weapons picked out.. two dire weasels shoot into the room attracted by the sounds of the breakout.
Optimal picks can be determined out of the Core Rulebook, with what is possible, attack mods and damage done per weapon per PC, without further clarification by the DM. Right? So what so you get?
