Discussion about Dungeon (Dark Elves).

Here's a question, maybe someone knows... As you know, the invisibility of the Ranger lasts for 3 turns. So, when a positive morale bonus triggers, does the invisibility end sooner, or is an additional turn of invisibility granted? Because if the invisibility ends sooner, it's more advantageous not to equip the Lion's Collar (+1 to morale) or similar items when clearing neutral creatures. And, by the way, it drops quite often at the beginning...
