 ===Fighting while invisible===
-Invisibility is a good evasive aid, usually resulting in hostile attackers missing more often unless you stay in one place; it is especially useful in the early game, where few monsters will have see invisible, and can aid in escape from unexpectedly powerful foes. This can also double as an offensive aid that helps you keep targets off-balance while picking them off from a distance, e.g., with [[projectile]]s or [[polearms]]. As the game progresses, you will encounter more monsters with see invisible, limiting its effectiveness (unless paired with something like displacement).

 Invisibility can actually be a disadvantage in certain scenarios: [[unicorn]]s in particular cannot see invisible and will not know the player's location to keep a knight's jump away, meaning that hostile unicorns will close in unexpectedly and likely skewer an early character. Conversely, invisible players can safely approach co-aligned unicorns to throw their [[gems]] at, and cross-aligned ones will be easier to kill or pacify for a prepared character. Invisibility can also make controlling other monsters for various purposes difficult if they lack see invisible, e.g., luring [[soldier]]s into [[trap door]]s in the [[Castle]] or pulling [[wraith]]s away from non-[[graveyard]] levels.
