Realistic D&D dinosaur campaign

[Lizerd]

Welcome to Lizerd's realistic D&D dinosaur campaign! Here is a brief description of what is to be going on and what you can expect.
Expectations and Warnings: you can expect realistically playing as an animal from hell creek formation. A map will be uploaded on graph paper.
Rules and mechanics are pretty brutal, infection, tripping, etc but for anyone. Please do not get grumpy with them, this is a realistic campaign. Furthermore character death is common if you make bad decisions. Again, don't get frustrated, a new character will be created. In a nutshell this game will not be forgiving, so please don't take anything personally, it is realistic. Dang that is a bad advertisement... But it will be fun  combat alone is worth playing
What you will need: You will need to have a brief look at a D&D 5e players handbook. You can use a pdf or get the actual book, however most of the character creation there and almost everything there will be useless, it is mostly needed for a basic understanding of the rules. The actual rules I have written may be some what confusing or not refined (one person wrote them, an ADHD 13 year old) but will be posted. For convenience copy them onto a word or google docs document for ease of use. Depending on smoothness of function they might be modified. Oh and you have to like dinosaurs 
Expect the rules to be posted very soon. Registration dates will be as follows:
First Season registration: August 11 to September 1st.
I will be running this on weekends expect the first season to end in December. Additional players can register after this on a weekend on this thread or sending me a personal message.

The goal of this is to be a simulation that one gives a taste, but is still fun. Hope you like it 

Enjoy!

Other note: Feel free to ask questions about this, you don't have to register by doing this.

Note: This does use D&D 5e combat rules, although modified so do familiarize yourself with D&D 5e combat and other basics as well as other basic terms.

Update Log: Expect to see a system for non-dinosaurs and animals per terrain to appear soon

Rules:
Biological systems:
SPECIAL NOTES:
Intelligence is reflective of animal intelligence, and wisdom represents experience. Int 30 would be human intelligence and 10 wis would mean average hunting experience. Wisdom thus varies with age and skill. Charisma is reflective of physical appearance, hence a second category threat charisma is added while base charisma represents attraction
Weight is measured factor, so is size.
Immune system is constitution +proficiency +10
Smell is seperate from perception, and the radius is used to determine how far a perception check can be made following in this order
Visual: advantage +3
¼ range: advantage
1/2 range: normal
¾ range:disadvantage
Max range: disadvantage -4

Corpses grant advantage to perception for locating them and can be located by animals smell by *3 for raptors and *5 for T.rex.

Drinking and hunger rules are as normal except:
Fat reserves, if you eat your max capacity your minimum for the next weeks is halved in a number equal to the amount of weeks you filled maximum capacity

[Lizerd]

Random Encounters:
Roll a d20 each hour for no animals encountered, for range break your range into quadrants s as follows
1-5 first quadrant
6-10 second quadrant
11-15 third
16-20 fourth

Distance is found by rolling a d4 and the result is how many tiles away, if it exceeded your range, the animal is undetected and forget it

When determining if the animal is living or dead roll a d4, on a one the animal is a carcass
The carcasses for any heard animal is one die of the normal roll made to determine value, with a t.rex there is only one individual.

[Lizerd]

Critical:
If a critical is rolled the effects are altered (A 20 on a 20 sided die). The hit will count as a head hit.  If a bone is broken by the damage, the break is on the head. If the damage is over ⅕ of the animals total health, the animal must beat a DC 16 constitution save or be knocked out. If damage is over ¼ the animal is sent into a coma for 2d6 days. Over ⅓ is death

Death & Unconsciousness :
If a target takes ½ of its health or takes a head hit the animal must make a  DC 16 constitution saving throw. Result is unconsciousness. The animal will wake up after 1d12 hours. If the animal took 2 head hits or ¾ damage of health the animal must beat a DC 18 constitution check or be knocked out for 1d20 hours. If the animal fails by rolling under 10, it goes into a coma for 2d6 days.

If animal has bled for 10 turns, use first knockout rules.
If animal has bled for 20 turns, use second knockout rules.

When an animal goes to zero health, it dies.

Movement:
Walking: Can be sustained for normal times, normal movement speed
Jog: Sustained for half as long as walking, full speed movement speed +10
Run: Sustained for a quarter: Double speed
Sprinting: Sustained for constitution plus dexterity small animals gaining +5 turns and medium +3. Round up. Triple speed

[Lizerd]

Health Regeneration:
Each day of rest the player can role 1 hit die + constitution to recover
Eat something to double effects

Bleeding:
Damage will vary with the significance
Bleeding: Takes three successful checks to end. Do not have to be in a row, each check is separated by 5 turns.

Piercing and slashing as well as general rules:
Damage: If less than 15, target takes d4 once every turn. First successful check causes the target to take the d4 once every 5 turns, a second check once every 10 turns.  DC 13
If damage was more than 15, target takes d8 once every turn. First check causes target to take damage 3 turns, after a second 7 turns DC 15
If more than 45 damage target takes d12 each turn, first check every other turn, second 4 turns. DC 18
Damage over 60: Target takes 3d6 each turn, fist check every other turn, second every 3 turns

Bludgeoning:
Has to be ⅓ of health damage taken
Beat a DC 15 if ⅓, DC 17 if ½ or greater
The target will have halved movement, and must make 3 checks, normal death saving throw system due to internal breeding

Bone Breakage:
Piercing: If damage is over 30 in one round, attacker must make a DC 15 str check to inflict broken bone.
If damage is over 50 attacker must beat a DC13 check to inflict breakage

Bludgeoning: If damage is over 20 make a DC 13, if over 30, DC 10, if over 40 the bone is automatically broken.

Effects of bone breakage:
Roll this D20 table

1-9 Broken leg, movement is halved, -5 and disadvantage on stealth
10-12 Broken arm, cannot make arm attacks with that arm
13-16 Broken ribs, if the victim moves more than 20 feet in a turn it takes 2d10 damage and starts medium bleeding.
17-19 Broken tail if the target moves more than 30 feet in a turn if must make a DC16 dex save or fall over
20 Broken skull, roll area If between 1-14 the upper section is broke, take half your hit points in damage, you cannot bite. If 15-20 lower jaw broke, you cannot bite and struggle to eat.

Healing Bones: Bones take a number of days equal to the damage caused by the breaking.

[Lizerd]

Sneak Attacks: Can be made after a successful stealth check. Attacker deals an extra half damage that it would originally deal.

Tendon rips:
Happens if a bone breaks and there is an excess of 15 or more damage. The target takes 2d10 damage, begins medium bleeding, and effects of the area double.
The bone break can heal but tendons in the arm cannot heal.
Tendons in other areas heal with the bone.

Infection: If you have a wound that is recovering the DM makes a roll against the DC of your immune system with +2 for each upgrade in size from small. If they win you are infected. For each day of infection take 1d10 damage, lose 10 spd, and consume water twice as quickly. Infection days is equal to the loss of health. After that certain number of days is waited on make a check, best out of 3 dc 13. If you win the infection ends. If you lose then the infection continues for those set days.

[Lizerd]

Collision system: Damage will vary on how fast and how large the victim was. Animals weighing less than 1 ton have the damage reduced to 1/4, and animals weighing less than 2 tons have damage halved. The victim will have to make a roll to stand up, see falling system.
If the victim was going between 1-30 feet damage is 1d10*1/10 weight (round down) DC 10. If the victim was going between 31-50 feet the damage is 3d10*¼ weight round down DC 14. If the victim dashed damage is 5d10*weight divided by 2 DC18

Falling: If the fall was from dashing target takes 4d10*weight (uses collision compensation)
If the fall was from collision target takes 2d10*weight
If the fall was tripping at low to medium speeds 3d10*weight
If the fall was tripping at high speeds damage is 5d10*weight
Animals on 4 legs have advantage on checks to stand up

Tripping and colliding: if the DC with effects is less than 10 there is no check
Terrain has effects on tripping:
Slope, weak incline, no check
Slope, medium incline DC 12
Slope, sharp íncline DC 15
Terrain with small objects that are lightly to mediumly dispersed: DC 13
Terrain with tightly packed small objects: DC 15
Terrain with trees, dispersed or small: DC 13
Terrain with trees, medium or medium packed: DC 15
Terrain with trees, large or tightly packed: DC 17
