Upgrading objects

Jump to: navigation, search

In SLASH'EM, items may be upgraded into other objects, by dipping them into a potion of gain level[1], or by the gnomish tinker technique. Listed are the various item transformations. If an object has multiple possible upgrades listed, the upgrades are equally likely unless otherwise noted. Note that upgrading objects does not break polymorphless conduct, and upgraded objects do not need to be dipped in a potion of restore ability to make the upgrade permanent, as polymorphed objects do in SLASH'EM. Much information taken from (and thanks to) Eva Myers's spoiler[2].

Note that artifacts cannot be upgraded, and will simply produce the Interesting... message.

Weapons and ammunition

Daggers

This is a good source of great daggers, since they are never randomly generated. As of SLASH'EM version 0.0.7E7F3, great daggers DO NOT STACK. This is by design.[3] If you upgrade to a stack of great daggers, it will be stacked ONLY until they are thrown or dropped individually. After that, they will never stack again

Strategy

Upgrading objects, either by potions of gain level or the tinker techinque, is the "poor hacker's polypiling"[4]. It can be used to get some good items without many of the the risks of polypiling. Most of the transformations are also reversible, although polypiling in SLASH'EM is by default reversible, since objects revert after some time. Also note that most of the magical items transform into other magical items, and mundane items change into other mundane items. Thus, with a few exceptions, it is not a viable way to make more magical items for polypiling. However, many useful items can be obtained, including helms of brilliance, healthstones, tinning kits and magic markers.

Cost and safety

One potion is used up per item (or stack of items) transformed, if using a potion of gain level. If using the tinker technique, much more time passes, using up food, and spawning enemies. Thus gnomes can save on potions, but must find a safe place to tinker, so they are neither interrupted or killed. Boulder forts work well, but may be hard to come by early in the game. Shops work very well in the early game, with the door locked. If you lack a way of (un)locking the door, you can also pick up an unpaid item, and let the shopkeeper block the door. Be sure not to stand in a straight line from the door, so monsters can't shoot you, and beware tunneling monsters.

Upgrading a container doesn't destroy its contents, as polymorphing does. However, if you upgrade a container to a bag of holding, it will explode if it contains an item that would cause an explosion[5].

Enchanted armor and weapons

One good use of upgrading is to get highly-enchanted armor or weapons. A +5 orcish helm may be upgraded into a +5 helm of brilliance. Also, since many transformations are reversible, the player may change a highly enchanted piece of armor from one type to another. For example, a wizard has less use of a +3 helm of telepathy than a +3 helm of brilliance. Similarly, a player could upgrade a +2 orcish dagger into a +2 great dagger, for two-weaponing with (or skill-training for) Magicbane. Additionally Elven armor can be enchanted, fairly reliably, to +7 and then upgraded. For example a +7 elven cloak can become something more useful like a cloak of magic resistance.

Polyfodder

Objects may also be upgraded for use in polypiling. Most magical items transform into other magical items, and most mundane items transform into other mundane items. Thus upgrading objects for polyfodder will often be a waste of potions or time spent tinkering. The exceptions are mundane items which transform into magical items:

  • flint stones
  • dwarvish helms
  • orcish helms
  • dented pots
  • dwarvish cloaks
  • orcish cloaks
  • leather gloves
  • robes
  • tin whistles
  • wooden harps
  • wooden flutes
  • tooled horns
  • sacks
