Honor

Honor is a Virtue and an Ilshenar Moongate.

When activated via the Virtues Menu, you may target a given creature that is entirely undamaged (that is, it's Hit Points, Stamina and Mana levels must be at their maximum). It could originally be used against players in addition to creatures, though this was removed in a later publish.

If you then kill the creature you are granted honor in accordance to it's fame level and how "honorably" you fought it. Allowing your target the first blow and staying close to it will grant you higher levels of honor then using ranged attacks from a distance.

Honor works hand in hand with Bushido in that activating it with a skill of 50 points or more also initiates the Perfection system.

Rewards

The reward for honorable combat is the ability to move amongst monsters without them becoming hostile to you. To do this, you must activate the virtue and target yourself. The effect ends after a certain time or when you next perform a hostile action.

I'm not entirely sure how often it may be used, nor how long it's effects last. I'm under the impression that this virtue only drains as you use it (as opposed to others such as Valor, which drain over time).
