WS-skill stack/cards?

[Fabre]

hello heROs, i am about to reset my WS, to get my last lvls. but since i only ever played free battle smith, i need help understanding the cart termination skill, it looks like it does mass damage. but costs money. the question________------===

does weapon effect, critical, cards, trigger effects, max overdrive/other attack increase skills, effect the attack/damage of CT.
or is it a skill that ignores my class skill damage buffs, and cards in weapon.

it will heavily effect my build, depending on this answer. and ive done as much search researching as i can, and i have yet to find a direct answer on-line. and i cant afford to reset a bunch of times to figure it out. so im hoping the server has info and suggestions, which i will value any input or info you may give to me.

luvs.
