The story(spoilers)

[Kes13a]

Negative impact could be small like rude,cruel remarks towards certain npcs, or bandit tactics like preventing uldah from get supplys.

Or even secretly changing your diety to others or non at all.

Maybe even go around punching lala characters in the face.

Maybe even add some drinkable rum,whiskey etc and pick up bad habits. Or you know like the one i said cursing and telling off hydelon.

Also side quest mostly cover history,land mass or how the area lives/functions outside a select few

Or maybe secretly crushing and going to spots showing certain npcs respect like niddhogg, emet etc

might want to try a drk...

not going to put too fine a point on it, but several of the job quests, both combat and crafting have some darker tones on them. you have barely scratched the surface and are an "expert".

simply because you prefer more fatal consequences, does not mean there are zero entailed.
