The Character Sheet
This is my Character Sheet
It contains my basic statistics, which by and large should be self explanatory to anyone with even the slightest experience of RPGs. Basically, higher is better.
Skill Values are increased with learning points according to the formula (N X 100), where "N" is the number you would like to buy. For example: Increasing Melee Combat from 50 to 51 would cost me 5100 learning points.
Base Attributes, on the other hand, are increased by eating the right types of food. Every time the meter below the Base Attributes is completely filled up, a "Food Event" triggers, and something happens. Usually (Almost always), Food Events increase a Base Attribute by one. The different colors in the meter determine the percent chance of triggering a certain effect.
Red: +1 Strength
Blue: +1 Agility
Light Blue (The big bar in the screenshot): +1 Intelligence
Purple: +1 Constitution
Orange (The small bar in the screenshot): +1 Perception
Light Green: +1 Charisma
There are also black food events which, on triggering, deal 5 HHP damage to your character. These are gained by eating some less wholesome foodstuffs, such as raw meat, but do not currently show up well against the meter's own black base color (Slight oversight, will be fixed).
Each foodstuff gives a set amount of Food Event Points (FEP) to the meter. The number of FEP required to fill up the meter are determined by the highest value among your base attributes (Having strength 61 as your highest value means you'll need 61 FEP to trigger a Food Event), so a varied diet is optimal at the moment. (We are considering altering this system somewhat, to encourage specialization, but that aside.)
When a FE triggers, the meter empties out. Overflow is always discarded.
Attributes can also be modified by certain equipment and/or personal beliefs. Bunny Slippers, for example, raise your agility by +2. Modified attributes show up as red (lowered) or green (raised), but the FEP-meter is always determined by your unmodified values.
In the future, food will inform you of its characteristics in this regard via their tooltip. Right now, they don't.
Happy levling!
