Polymorph
Spoiler Warning: This page contains spoilers which may affect your IVAN experience negatively
Polymorphing transforms items into diferent items and your character or monsters into different monsters. For example, a rock can be polymorphed into a scroll, and a human can be polymorphed into a buffalo. There are various methods how to polymorph and how to control it.
Drinking from fountains or stepping through magic gas (released by Magic Mushrooms or Staff of wondrous smells) can possibly polymorph you or give you PolyControl and/or Polymorphing intrinsics.
Items
Wand of Polymorph
You can polymorph creatures (including yourself), items, and altars with a wand of polymorph.
Zapping a wand of polymorph will polymorph any objects or creatures within a 5 block range. Up to five items on each block (the five closest to the ground) will be polymorphed. Some items cannot be created through this method, such as scrolls of charging. Some creatures, mainly the named creatures, cannot be polymorphed.
Applying or otherwise destroying a wand of polymorph will polymorph any objects or creatures in a 3x3 grid centered on the wand.
Ring of Polymorph
Wearing a ring of polymorph will cause the character to polymorph randomly. However, it does not give the character PolyControl, so it is risky to wear one on its own.
Chameleon Whip
A chameleon whip will sometimes have the effect of polymorphing the creature which is it hits.
Monsters
The only creature that polymorphs on its own is the Chameleon. Chameleons will polymorph when they feel threatened, and can polymorph into any non-named monster.
However, eating the corpses of mutant bunnies, mutant asses or chameleons will polymorph the player. Eating giant mushrooms will occasionally have this effect.
PolyControl
PolyControl is a state which allows the character to choose which creature they polymorph into. The easiest way to be permanently in this state is to wear a Ring of PolyControl. You can also temporarily have PolyControl by eating a magical mushroom or drinking from a fountain. Wielding Valpurus's Justifier will also bestow PolyControl on the character.
Whenever you polymorph with a PolyControl active, you will be prompted to choose which creature to polymorh into. Pressing Ecs or choosing human will cancel the polymorph, as you are human by default. Otherwise, you have to see a creature al least once to be able to assume its form, as well as your Intelligence have to be sufficient. See individual creature entries for PolyControl requirements.
It is not possible to control polymorphing of items.
Polymorphitis
An uncomfortable uncertainty of who you really are overwhelms you.
Polymorphitis is a status that forces you to polymorph into a monster at random. If you do not have a means of polycontrol, the monster you transform into will also be random - although there is a higher chance of you polymorphing into something with better stats than yours than something with worse stats.
If you do have a means of polycontrol, you will be prompted to select a form to take whenever your polymorphitis triggers - though what you can polymorph into will now be limited by your INT.
Lycanthropy
Lycanthropy is a special form of polymorph associated with werewolves. It will randomly turn you into a werewolf, but can be controlled with PolyControl.
