Deeds are achievements of noteworthy significance - some only achievable once in a lifetime - and if/when you complete one of the deeds a mark is placed in your character history, announcement across the realm, and a step more taken towards building a legend.
There are a few hundred deeds in total but many are mutually exclusive by dint of alignment or fighter versus pacifist perquisite so the required number of deeds to achieve the "legend" standing is one hundred. Simple as that.
Shows you a summary of those deeds you have performed worthy of note and contributing ongoing to your stature and reputation.
Syntax: DEED LIST.
Gives you a list of at least two dozen potential deeds currently recommended for your character based on standing, fighter/pacifist/duellist status, experience level, profession and guild, city or divine allegiances.
Completion of a deed or recognition of a deed from your past brings a hefty bonus in experience points (depending on the deed's rated difficulty/rarity) and if the deed is achieved in the present, it contributes a marked boost to your reputation - thus aiding your city and guild vis-v-vis rival cities and guilds, contributing to the divine globe and guild reputation available for sponsorship and globe allocations/powers.
