I'll necro this a bit!
Extra Ability Skill Bonus
Choose one ability. All trained skills based on that ability receive a minimum ability bonus of +4 regardless of your actual ability score. Note that in order for skills to qualify for this bonus, they must be a core part of your character concept and background.
I think making this into a
You can use a different ability score for this skill [maybe only specific actions/situations]
Would work a bit better for the flow.
Increased ranged weapon damage
All ranged attacks add half of the attacker’s Dexterity to damage as long as all targets are within half of the weapon’s range increment. This does not stack with the Propulsive trait.
I don't think this is a good idea. Going strength on a ranged char is costly already and a pc with 18 in str on level 1 then just has a +1 on their damage on ranged weapons. Also as it is written thrown weapons gain the strength bonus and dex bonus to damage.
Increased spell damage All damaging spells add the caster’s key ability to damage for one of the targets (chosen by the caster). This effect occurs only when all targets of the spell are within half of the spell’s range.
That's probably fine, early game damage is a bit low. Maybe excluding Electric Arc specifally would be a good idea.
Daze You push into the target's mind and daze it with a mental jolt. The jolt deals 1 mental damage, with a basic Will save. If the target fails the save, it is also stunned 1. It is stunned 2 if it critically fails.
Heightened (+1) The damage increases by 1.
No to the crit fail, that's too much. Having a boss roll a one against a cantrip should not basically invalidate a whole round
Assurance Fortune, General, Skill Prerequisites: trained in at least one skill
Even in the worst circumstances, you can perform basic tasks. Choose a skill you’re trained in. Once per ten minutes you can roll two dice and use the higher roll (do not apply any other bonuses, penalties, or modifiers).
Probably a good idea, but the base effect of assurance is fine to keep without a cooldown.
