If you eat or drink in the arena, post here with a link to the specific post. Failure to post here will result in characters losing points--even if you state that they're eating in the actual RP threads. I don't have time to track down every single character's threads to make sure that they ate and drank.
Each character needs to drink 1/2 gallon of water a day in order to be considered hydrated. You don't have to specifically say that your character drank exactly 1/2 gallon as long as you convey through your writing that your character drank an adequate amount.
+ Drink adequate amount of water (1/2 gallon) = no penalty
+ Drink adequate amount of unclean water (1/2 gallon) = lose 10 HP
+ Drink inadequate amount of clean water (1/4 gallon) = lose 15 HP
+ Drink no water or less than adequate of unclean water = lose 20 HP first day, 20 HP the second day, 20 HP the third day, and death the fourth day
If your character goes a day without water or without enough water, the character can gain half of it back if he/she drinks twice the amount of water the following day. So let's say that Bob the Tribute loses 20 HP for not drinking water on Day 3, but then drinks a whole gallon on Day 4 (that's 1/2 gallon x 2), then he can gain 10 HP back in addition to whatever health bonus he has. However, he can only gain the points back from the day before--not from Days 1 or 2 if he went without water or didn't drink enough.
There is no minimum amount of food necessary for a character to eat as long as it is written reasonably. Meals must be substantial. You can't have someone eat three bites of food and call him/herself good.
+ Eat food = no penalty
+ Don't eat food = loss of 20 HP each day
+ No food for five days = death
Day 1 Exception
We can assume that the characters had something to eat and drink the morning of Day 1 (before the entered the arena), so they will not lose points for failure to eat or drink in Day 1. However, if they fail to drink water on Day 1-Day3, they will still die of dehydration on Day 4.
