New item: Spiked collar leash.
The spiked collar leash can be equipped like a rope, and used to try and subdue bears (quell the beast to get 100 tameness points on them)
Subdued bears change into fighting bears, which have the same (or higher) combat stats as X bears, but the LP value and products of V (or lesser?) bears.
(because I think good quality bear products should stay somewhat rare)
New construction: Breeding pit
Once you have subdued your bear, drag it here, and release it into the pit (rightclick pit with leashed bear?).
Now, head back into the woods, and capture your bear a mate.
Next, kill some animals, and fill your breeding pit's food hold with raw meat and/or fish.
Soon, your bears should mate and pop out a cub. Bear pregnancy should last about the same time as cow pregnancy I think.
Bear maturing should last somewhat longer.
New construction: Fighting pit
Brag to your friends and enemies about how you are going to fight 5 bears at the same time and win.
Place bets if you will.
Move the preferred number of fighting bears to the fighting pit, gather the crowd, and jump in the pit.
The fighting pit should have a right-click option: 'Death on KO', to spice up fights.
