John: Bum. Gross. Weird. Definitely had an ulterior motive to stick his hand down my throat. Cool, otherwise.
Archibald: Probably the sanest person in the group. A little too rigid on the 'rules', but whatever. Feel bad for him sometimes. Would trust with a toddler.
Durge: Quiet. At least a little mentally ill. Idiotic at times. Blunt with his words, but in a good way. No clue what's going on what's going on in his head.
Rope: Bit of a drama queen. Seems like she has a lot on her shoulders. Wish she would stop bitching so much, though. She needs to get rid of Siegfried sooner rather than later

Call of the Akashic Records (Tactical Knowledge Checks). The Akashic Records is a library containing all written knowledge in the world. Everyone can access a snippet of this information in battle to learn information about the enemies they fight and what they are capable of, taking that power from the records and reading it. All mortals have this capability so long as they have a soul.
In combat, all characters are allowed one free skill check that can be used at any point in your turn that doesn't cost your Action or Bonus Action. This can be used to make a Call of the Akashic Records check or a different skill. When choosing the Call of the Akashic Records, once per turn, you can make an Intelligence (Investigation or Arcana) check against any creature you have seen fight. As long as you succeed against a set DC you can learn one useful fact of your choice about the target's combat abilities. (A different skill check can potentially be used so long as it makes sense, e.g. Nature to discern plant type enemies, otherwise this check will always use Investigation/Arcana). You may still use your regular Action to make an Investigation/Arcana check if you wish to check twice. On a Natural 20 you may learn two pieces of information rather than one and treat the dice roll as if you rolled a 25. The list below details the DCs for what you can learn about the enemies you face against:
Call of the Akashic Records Check DCs

10 - A simple explanation on its movement, or one special sense they possess

12 - A category name or the creature's type

14 - An ability, legendary action or reaction

16 - A creature's next move aka its tactic/feeling

18 - A resistance or immunity to a damage type/condition

20 - A vulnerability or weakness of the creature (if none then you learn their resistances or immunities instead)

25 - Any information of the creature that makes sense

Instead of an Investigation or Arcana check to discern a creature's combat abilities, you may elect to choose a different skill check for your free skill action instead (You may not use a Stealth check or a Medicine check to stabilize a creature at 0hp using this free skill check action). Here are some ways you may utilize using a skill check in this way:
Intimidation: You may potentially taunt a creature to attack you instead. Make an opposed Intimidation check against a creature's Wisdom Save. On a success they will target you instead. (This doesn't prevent them from using multitarget attacks/AoE's to hit you and everyone else).
Persuasion: The potential to gradually deescalate the fight altogether.
Sleight of Hand: You may make a Slight of Hand check against a creature's opposed Athletics/Acrobatics check to potentially steal one random item that is not being held or worn by the target. (Need to make an Investigation check prior to try and steal a specific item).
The Call of the Akashic Records is mainly to be used whilst within combat. Outside of Initiative, you can still make a few limited checks on someone like knowing their level/CR but you can't identify their abilities unless you are fighting. Smarter enemies are also capable of using the Call of the Akashic Records against you.

Faith Checks. A Faith check is something that may allow you direct contact and response from the very gods themselves or some situation may be relevant to call upon divine attention. Once a long rest you may choose to call out to a god of your choosing by rolling a flat 1d20. Clerics, Paladins or followers of a certain god may add their proficiency bonus to this roll. If a Cleric or Paladin makes contact with their own god then they gain Expertise on the roll. What happens afterwards will be up to the DM depending on what you rolled.
Warning: Rolling a 1 may get you smited. Additionally, if you're a race that doesn't have a heart (only Humans, Tieflings and Aasimars have them), attempting a Faith check will expend 1 month of your character's lifespan so make sure what you're saying matters.

Clashes. A Clash is something a character can choose to perform in combat to put everything on the line and make a Hail Mary against their enemies. A test of metal against one another where victory may change the tides, but failure may spell your end. A Clash can only be performed by expending an Action, performing a Clash within 5 feet of the enemy and only under certain circumstances, such as when a certain amount of health has been depleted.
Once a Clash is issued, the DM will give a bunch of Clash options that the player may choose from, these usually involve the following:

Martial Clash: Roll an attack against each other with a martial weapon.

Arcane Clash: Roll a spell attack against each other. This works like a martial clash except the output of the clash will relate to the spell casted. If the spell is a saving throw both targets have to make the save.

Special Clashes: There are other specific clashes that can relate to races, classes, alignments, divinity or any other option. The clash output for these tend to be higher compared to the other default clashes.

Multi Clash: You and other party members may Ready their Action to Clash together as a team. Both of you roll and the higher dice result between you is chosen. However, the more people join the clash the more risk is posed to all parties involved.

Winning the clash roll grants a +1 to the clash counter. You then will roll against each other multiple times, first one to reach 6 wins the Clash (There may be moments where the threshold to win goes higher than 6). Rolling a 20 adds +2 to the counter, rolling a 1 adds +2 to the opponent and rolling a 20 against a 1 is a +4. If the same number is rolled for both parties then the clash output is doubled.
Depending on the number difference, e.g. a 6-2 will determine how much the clash affects the loser.
If an ally is within 5ft. but not part of the Clash itself, they may use their Reaction to offer the one Clashing the Help action. An enemy's Clash modifiers become lower the less hp they have before the Clash.

Glory Kills. A Glory Kill allows you to have full control in describing how you take out an enemy. Roll an Athletics/Acrobatics check, if you roll higher than their current HP you can perform a Glory Kill. They however make an Athletics/Acrobatics roll in return, if they roll higher than your roll then they can perform a Glory Kill instead against you (Their roll has to be higher than your current hp to be able to Glory Kill you back, otherwise nothing happens.)

Saving Throw Rework. Saving throws can have critical fails or critical successes. On a nat 20 save, you go under the effects of evasion. If you should roll a nat 1 then you take damage as if you had been critically hit.
A spell that makes you do a DC 22 save and you roll a nat 20 but don't beat the DC (Due to not having the stat), you don't take the damage if there is one but you would still undergo the effects of that spell. E.g. Tasha's Mind Whip.
Disarm. 1 action. A creature can use a weapon attack to knock a weapon or another item from a target's grasp. The attacker makes an attack roll contested by the target's Strength (Athletics) check or Dexterity (Acrobatics) check. If the attacker wins the contest, the attack causes no damage or other ill effect, but the defender drops the item.
The attacker has disadvantage on its attack roll if the target is holding the item with two or more hands. The target has advantage on its ability check if it is larger than the attacking creature, or disadvantage if it is smaller.
Healing Surge. 1 action. As an action, a character can use a healing surge and spend up to half his or her Hit Dice. For each Hit Die spent in this way, the player rolls the die and adds the character's Constitution modifier. The character regains hit points equal to the total. The player can decide to spend an additional Hit Die after each roll.
A character who uses a healing surge can't do so again until he or she finishes a short or long rest. Under this optional rule, a character regains all spent Hit Dice at the end of a long rest. With a short rest, a character regains Hit Dice equal to his or her level divided by four (minimum of one dice).
Mark. Free. This option makes it easier for melee combatants to harry each other with opportunity attacks.
When a creature makes a melee attack, it can also mark its target. Until the end of the attacker's next turn, any opportunity attack it makes against the marked target has advantage. The opportunity attack doesn't expend the attacker's reaction, but the attacker can't make the attack if anything, such as the incapacitated condition or the shocking grasp spell, is preventing it from taking reactions. The attacker is limited to one opportunity attack per turn.
Overrun. 1 action. When a creature tries to move through a hostile creature's space, the mover can try to force its way through by overrunning the hostile creature. As an action or a bonus action, the mover makes a Strength (Athletics) check contested by the hostile creature's Strength (Athletics) check. The creature attempting the overrun has advantage on this check if it is larger than the hostile creature, or disadvantage if it is smaller. If the mover wins the contest, it can move through the hostile creature's space once this turn.
Tumble. 1 action. A creature can try to tumble through a hostile creature's space, ducking and weaving past the opponent. As an action or a bonus action, the tumbler makes a Dexterity (Acrobatics) check contested by the hostile creature's Dexterity (Acrobatics) check. If the tumbler wins the contest, it can move through the hostile creature's space once this turn.
Incapacitated Rework. Whilst under the Incapacitated condition, or any other spell or magical effect that would skip your turn, rather than being unable to take actions or reactions, you instead go under all the effects of the Slow Spell. All other effects caused by conditions that additionally apply the Incapacitated condition still apply (i.e. Paralyzed still turns successful melee hits into critical hits, Stunned still will make you automatically fail Strength and Dexterity saving throws etc.)
This only applies to players. The Incapacitated condition works as normal for enemies.
Death Saves: Additionally, when making Death Saves, you can still use your movement to drag yourself, however, it counts as prone movement.
