This update adds Portuguese language support, the invisibility spell, and some minor user interface improvements.
The invisibility spell is an interesting one. It doesn't cost much mana to cast, but it requires (passive) maintenance. Each step you take costs one mana to stay invisible, and the spell will wear off if you run out of mana. In addition, doing anything useful like resting, meditating, or attacking will break your concentration and deactivate the spell. Monsters that are already attacking you won't be able to attack, but they will follow you (because you still make sounds and smells), but monsters that are not already aggro will not notice you. This means that it might be particularly useful to sneak past a dangerous group of monsters.
