New Rules

Bonus Feat

You gain a free bonus feat at level 10

Intelligence Buff

To make intelligence more viable, for each intelligence modifier you have above zero, you are able to learn a new language, tool proficiency, insturment, game, etc.

Restricted Help Action

You can only use the help action if you are both proficient in the ability (unless you can justify a good reason why you should still be able to)

Banned Spells

These spells aren't as compatable with a plot and world that revolves around intrigue, information, and mystery. Other spells might simply disrupt plots, or be anti-fun in combat:

ressurection

revivify

raise dead

hold person

counter spell

plane shift

long range teleportation spells

Guidance

protection from poison

Detect Thoughts

Speak with Dead

Wish

Strength Buff

You gain certain additional advantages based on your strength score and level
At level 3, with a strength level of at least 14:

You become proficient with all improvised weapons

You are able to use strength for all intimidation checks

You become immune to the afraid condition

You can use your strength modifier for ranged weapons

At level 8, with a strength level of at least 17:

Exhaustion is reduced by one level, meaning two causes of exhaustion must accumulate before one level is incurred.

Fall damage does not begin being tallied until 100 feet of distance fallen

Attacks that hit against a 1 hitpoint creature will automatically hit an adjacent 1 hitpoint creature of your choice within range. Damage received from a 1 hitpoint creature can be reduced by your strength modifier.

When you must make a dexterity saving throw, you can roll 1D6. On a 5 or 6 you are able to use your Strength saving throw instead of dexterity

At level 13 with a strength of at least 20:

You can grapple up to Huge sized creatures

Your lifting capacity becomes an amount of physical force you can exert in general. This force raises to thousands of pounds of force. Acts like throwing a large creature, or tearing a door off its hinges become casual acts that can be done without an athletics check. Athletics checks can instead now be used for truly herculean feats like tearing a giant greek column from its base and throwing it hundreds of feet, collapsing a stone building with your bare hands, or bending steel like a pretzel.

Your movement increases by an amount equal to 5 + 5 x your strength modifier (additional 30ft for 20 strength) when jumping with a 10 foot running start, or half of that on a standing jump.
