Is it a bad idea to have a water candle in my house?

I have collected a couple of water candles from the Dungeon biome and since reading the item description and the wiki article about it I realise that may have been a bad idea:

Holding this may cause unwanted attention.

However, now that I have bought them back to my spawn point, I was wondering if there are any bad effects of using them as a light source in my home?

• By the way, if you find yourself doing `switch` statements like this (like this probably was originally), you probably want to use polymorphism instead :) Jun 4, 2011 at 3:17
• Another note about your math (sorry): decreasing the spawn-delay by `25%` is not the same as increasing its inverse (the spawn-rate) by `25%`. It actually increases the spawn-rate by `33%` (because multiplying the spawn-delay by `3/4` is the same as multiplying its inverse by `4/3`). For example, if the spawn-delay were originally 1-second-between-monster-spawns, and we decreased that to 0.75-seconds-between-monster-spawns, then after 100 seconds, we originally would have had 100 monsters, but with the new spawn-delay we'll have 133 monsters, a 33% increase.

• Actually, delay may not have been the right word. A random number between 0 and `spawnRate` is rolled, and if that number is 0, an NPC spawns. By default, that's `1/701`; after this adjustment it would be `1/526`. So, the higher the spawn rate, the higher the delay, on average, between spawns. Jun 5, 2011 at 9:57
