BUILD QUESTION

i used rivers of blood for my entire first playthrough (dlc included) and after i started to play strenght-faith for my second playthrough. idk why i was bored of it maybe the spells was not cool enough at begining or blasphemous blade was too boring; i started using elenoras poleblade. well, it is so fun but its aow is very open for attacks and heavy attack is a little bit slow but it was still fun. i was trying to beat dragonlord plasiduax today, the fight lasted 10 minutes because of my damage lowness since i could only use light attacks (i died btw). but i was unsatisfied by the damage idk is boss too resistant to bleed and fire and psyhcal? my triple combo attack was only doing 1000 damage. i am sure i am not build wrong or no buff user since i watched a lot of guides. im not asking something to beat the dragonlord btw i hope i can beat him after few tries but;

in the endgame i acquired a lot of cool (especially lightning) incantacitons which i wanted to use. (and i believe i will get one too after beating dragonlord) but i also want to use a very cool looking sword effectivly too. i dont want to be cracked but also not weak.

are there any builds that includes lightning incantacitons and a cool looking sword? or maybe something very different then a faith build idk i just want to look cool while the bosses beat my ass
