Eating an amulet of reflection (which doesn’t provide any intrinsic) causes you to “reflect on your inner self”, providing enlightenment.

If enlightenment tells you something like “You have [intrinsic] from your [piece of gear you didn’t know the property of], that object property becomes identified on that piece of gear.

Add a spell of insight, a level 2 divination spell which grants enlightenment.

In variants with percentage intrinsics, intrinsics granted by one’s role need not be binary. For instance, monks tend to gain a lot of elemental resistances by leveling up, so rather than having those be all-or-nothing cutoffs at fixed levels, spread it out so that they gain a decent percentage of the resistance with each level near the original cutoff.

This would complicate the enlightenment display, since now it would have to disclose something like “You have 76% fire resistance: 45% from corpses and 31% from your priest levels”.

A new object or, more likely, an artifact which is a ring of enlightenment. Wearing it increases Intelligence and Wisdom by 1. Additionally, when you perform the #attributes command, you are shown your fire, cold, shock, poison, and sleep resistance statuses. Possibly it can be invoked for full enlightenment.

Reading a noncursed scroll of amnesia while confused “clears your mind”, which cures the confusion and sometimes gives you enlightenment, but the regular amnesia effects still happen too.

The blessed potion of hallucination, in addition to making you hallucinate, grants enlightenment (maybe a “corrupted” enlightenment where there’s only a 50% chance of seeing things you can’t see through the ^X command)

Merge the wand of enlightenment into the wand of probing: probing gives enlightenment when zapped at yourself.

Spell of probing, in the divination school, that probes monsters based on skill:

• Unskilled limits it to touch range and gives minimal information on the monster’s status, possibly only showing HP like a stethoscope.
• Basic is still touch range but gives the usual amount of information.
• Skilled shoots a probing beam and gives some additional information.
• Expert allows you to select any space or monster in your line of sight within a radius, and gives the same information as Skilled.

The wand of probing is raised to be on par with the Skilled effects.

Give the Magic Mirror of Merlin an invoke effect of enlightenment.

If the Wizard has started to harass you, enlightenment shows “You are being harassed.”

Reading a scroll of knowledge while confused or hallucinating gives you enlightenment instead.

You can pray at a gravestone, or possibly ring a bell at one, to cause any of a number of good and bad effects:

• Summon a ghost, which might be hostile or peaceful.
• Summon a hostile undead, flavored as it forcing its way up out of the grave. Usually a zombie.
• Polymorph you into a zombie or mummy of your own race.
• Put you to sleep, ignoring resistance.
• Create a swarm of hostile manes or lemures.
• The headstone falls on your foot, dealing some damage, less if wearing boots (“killed by a falling tombstone” if fatal).
• If the grave is a bones pile grave, the ghost of the player always appears. It will be peaceful if their alignment matched your own and hostile otherwise.
• Various cosmetic messages that do nothing. “The air suddenly turns cold.” “The engraving on the headstone shimmers for a moment.” “A shiver runs down your spine.”
• The dirt cracks open and spits out any items buried under it.
• A voice from nowhere whispers a random rumor, true or false.
• The epitaph on the grave changes. This does not flag the grave.
• Get an alignment bonus for honoring the dead (this is only if triggered by praying). “You feel that the one buried here is content.” Bonus might be larger if you’re lawful or a Priest, probably 1 otherwise. This should possibly happen before and independently of any other effects.
• Limited identify of 1 item.
• Type-identify of multiple un-type-identified items in the inventory, but the player doesn’t get to pick which. Might pick 0 items (flavored as the spirit not knowing anything new about what the hero is carrying).
• Enlightenment.
• Temporary telepathy / sleep resistance / infravision / other intrinsic.
• The gravestone rumbles and moves aside, revealing a branch staircase to a just-created-now one-level branch, a small one-off “crypt” floating branch that contains some undead, some boxes containing corpses, and some treasure. This only happens on gravestones in the Dungeons of Doom.
• You “feel that the dead are restless”, aggravating monsters level-wide. All gravestones on the level become flagged against further attempts. This effect could be added to and independent of other ones, and if so, it’s a chance dependent on the number of already flagged gravestones on the level, which provides a nice way to balance it on levels that have massive amounts of gravestones.

After you get one effect, the gravestone is flagged so that it doesn’t happen again (or, more evilly, that any further attempts will only result in bad effects). Possibly shouldn’t work at all on graveyard levels, because they have too many graves to balance these effects.

Enlightenment tells you how many more turns you have for timing-out effects.

High level (maybe only XL 30) monks can get enlightenment by sitting on normal floor.

When reading a scroll of identify when confused, you get enlightenment (you’re “identifying yourself”).

If you die with zero points, end-of-game enlightenment says “You were a noob.”
