Skills

Skills can range from 0 to 99 and go up randomly (meaning: no, there will not be a skill bar added telling you when you will get your next skill) depending on the percentage of experience you're putting towards skills. This percentage can be changed under the skills menu, which is also where you can change the skill you wish to put points towards. The higher percentage of experience you have going to skills the higher your chance of getting a skill increase. You can only train one skill at a time, but you can be proficient in multiple skill categories. Skills become more difficult to improve as they mature. You can type /skills at any time to see the rating of all your skills.

Kingmanship - This allows a kingdom to gain increasing interest on all kingdom aspects on the five standard planes (except for treasury and guard) every hour, granted the King is currently present. Kingdom aspects include Population, Morale, Food, Army, Walls, Moats and Cannons.
At a skill of 99, kingdom aspects will go up by 1% per hour and you will gain an additional 50% interest.
At a skill of 125, kingdom aspects will go up by 1.25% per hour and you will gain an additional 62.5% interest. For more info see the relic combos on the relics page.

In the Forge, Kingmanship has the effect of increasing the interest bonus innate to some locations by +1% per skill point, up to +125%. If 0 bonus to start, there is no benefit.

Haste - This lowers the delay associated with all game actions.
At a skill of 99, all game action delays will take 50% as much time as usual.
At a skill of 125, all game action delays will take 44% as much time as usual.

Defensive - This increases your ability to withstand damage.
At a skill 99, you will be able to withstand 25 TIMES more damage.
At a skill 125, you will be able to withstand 832 TIMES more damage.

Monk Discipline - Players will be able to do damage with just their fists if they have NO weapons and NO shields in either hand. This skill turns your fists into weapons: a 0 in the skill is like a rusty dagger, a 69 is like a Rustless Lifeceaser, a 70 is like a Mace of Ressurection and beyond that is incredible power (30% more power each time you go up a single point). Unlike other fighters, Monks do damage based on Cnt and their chance of landing a blow is dependant on Agi, so basically their Cnt is their Str and their Agi is their Dex.
At a skill of 99, you'd do approximately 2,500 times more damage than you would with a Rustless Lifeceaser.
At a skill of 125, you'd do approximately 30,000 times more damage than you would with a Rustless Lifeceaser.

Ruby/Sapphire/Emerald Hoarding - In the Forge, certain locations provide an innate bonus to finding rare essences. These skills enhance that bonus by +1% per skill point, up to +125%. If 0 bonus to start, there is no benefit.
