Can be filled with any type of item. 12. * 3. May be carried in one or both hands. 13. * 4. Is used as the melee weapon and as the launcher for 14. * ammunition. 15. * 5. Only conveys intrinsics when it is a weapon, weapon-tool, 16. * or artifact. 17. * 6. Certain cursed items will weld to the hand and cannot be 18. * unwielded or dropped. See erodeable_wep() and will_weld() 19. * below for the list of which items apply. 20. * 21. * The secondary weapon (uswapwep): 22. * 1. Is filled by the e(x)change command, which swaps this slot 23. * with the main weapon. If the "pushweapon" option is set, 24. * the (w)ield command will also store the old weapon in the 25. * secondary slot. 26. * 2. Can be field with anything that will fit in the main weapon 27. * slot; that is, any type of item. 28. * 3. Is usually NOT considered to be carried in the hands. 29. * That would force too many checks among the main weapon, 30. * second weapon, shield, gloves, and rings; and it would 31. * further be complicated by bimanual weapons. A special 32. * exception is made for two-weapon combat. 33. * 4. Is used as the second weapon for two-weapon combat, and as 34. * a convenience to swap with the main weapon. 35. * 5. Never conveys intrinsics. 36. * 6. Cursed items never weld (see #3 for reasons), but they also 37. * prevent two-weapon combat. 38. * 39. * The quiver (uquiver): 40. * 1. Is filled by the (Q)uiver command. 41. * 2. Can be filled with any type of item. 42. * 3. Is considered to be carried in a special part of the pack. 43. * 4. Is used as the item to throw with the (f)ire command. 44. * This is a convenience over the normal (t)hrow command. 45. * 5. Never conveys intrinsics. 46. * 6. Cursed items never weld; their effect is handled by the normal 47. * throwing code. 48. * 49. * No item may be in more than one of these slots. 50. */ 51. 52.
