Luck

Luck affects many different skills and abilities in ways that are still as yet unknown. It is one of the hardest attributes to increase, the other being Speed. It is not displayed on the character information screen.

What Luck Affects

After cheating to huge amounts of luck, many effects are easily observable. Luck has an effect on

• Fishing - getting fish instead of junk
• Greater Evasion
• Eye of Mind
• Playing blackjack
• Finding good random events
• Preventing bad random events
• Quality of equipment drops: This affects the *number* as well as the *quality* of the drops. The easiest way to see the difference is to visit the strange scientist and see what she has to offer, then get a lucky day or cheating your luck up and going back to visit her. You'll notice that there are more options and some of the ones that were miracle quality might even now be godly quality.
  • Specifically, each generated piece of equipment is given a random quality (good, great, etc.). Then, a random number up to 5000 is rolled, and compared to your luck. If your luck is higher, the equip quality will increase by one level (great increases to miracle, for instance).
  • Increased quality does not mean better! It just means you (usually) have a few more attributes, which could include "Decreases Luck by 20". It also doesn't change how common specific attributes are (maintains [stat] > increases/decreases [skill] > prevents blindness/confusion/etc > increases [stat] / resistance > everything else pretty much). 
  • It increases the chance of furniture having extra modifiers, though material quality will be based on the level of the area - you will find at best inferior materials on the first floor of puppy dungeon, for instance. If obtained during a wish it will be based on your level, if bought from a shopkeeper it will be based on his rank, and if made with a crafting skill it will be based on the appropriate skill.
  • As luck increases: When ore appears, it will more often be higher value (Still only junk stones in wilderness maps though...). When gold is dropped, it's likely there will be more gold. When scrolls, potions, and spellbooks are generated, they will more often be higher value items (not necessarily more useful, since Oracle and Name are rather high value...). There are general limits to these - potions of corruption will not usually show up on the ground in level 1 dungeons, and scrolls of growth or spellbooks of domination will not appear that early on either. Though they will show up earlier and more often than usual.
  • Luck affects containers twice: When they are generated, and when they are opened. If lucky when generating chests, they will give higher-level loot (steel vs iron, diamond vs perl, etc), and if lucky when opening chests, they will give better quality loot (miracle vs great, better ores, etc).
  • If a creature is killed by an assassination event, anemia, or bloodsucking equipment, your luck will affect what they drop.
• Increases the spawn of rare creatures: This can be both good and bad. More Big Daddies will show up in dungeons, and gold bells and platina bells will show up more often. Silver cats as well. Special NPCs will show up in Party Time! Quests, too. Quickling Archers, Executioners, and Mine Dogs will also appear more frequently, so you may end up dying or losing pets without knowing what happened.
• All increases are on average, so even with high luck you will still get bad loot, and you will still go over 21 in blackjack, and you will still get junk when fishing.

but has no observable effect on

• Weather
• Stealing
• Ether disease
• Number or quality of job offers
• Hit rate
• Damage
• Whether or not items are cursed, blessed, or doomed
• Equipment held by enemies
• Drops from enemies killed by your pets or neutral NPCs (the killing blow determines whose luck is used)
• Results of drinking from a fountain

Increasing your Luck

There are only six known ways to permanently increase your luck, those being:

• Taking the three feats that increase Luck.
• Wishing for Skillluck.
• Getting a luck boost from Ehekatl of Luck if you worship her.
• Eating a rabbit's tail (item, not material).
• Eating a happy apple.
• Eating a kagami mochi
• In Elona+, eating raw equipment that gives bonuses to luck will train your luck. (at least in 1.15 and up)
• Also in Elona+, completing the Lost Kitty quest will train luck by a small amount each time you complete it (the quest is repeatable)
• In Elona+, eating a Four-leaf clover trains luck, and increases its potential a little bit.

Luck can also be temporarily increased by:

• Having a lucky day (a random buff obtained when sleeping that lasts for 1500 turns).
• Eating blessed food (version 1.14).
• Using a Statue of Ehekatl (buff lasts for 2500 turns)

The exact values of these temporary increases vary and are shown as a hint on the character sheet.

How Much Luck Increases By

Characters have a starting luck value of 50.

• Getting a luck feat adds +5 luck. This can be done 3 times to total +15 luck.
• Wishing for "skillluck" gives +1 luck
• Wearing mica equipment gives +3 luck while it's equipped
• Eating a rabbit's tail gives +1 luck
• Eating a kagami mochi gives +2 luck
• Eating a happy apple gives +20 luck
• Having a Lucky Day boosts luck by 777 for 1500 turns
• Feeling lucky from blessed food boosts luck by 100 for around 700 turns
• Using the Statue of Ehekatl boosts luck by 77 for 2500 turns

Luck doesn't have a potential associated to it (unlike Speed and the base attributes), so a Happy Apple will always give 20 luck and a Rabbit's Tail will always give 1 luck. Base luck is capped at 2000.
