Ok, I'll try that! Thanks.
Is it normal that bosses are glitchy when being summoned? I could not help in a Volnir fight because his hands always clipped through the ground...
You have to be hollowed (the more the better) and push your luck stat. Than you hollow infuse your weapon and shield to get another 10 points in luck.
Use carthus rouge and watch enemies bleed
I used it with Onikiri and Ubadachi and the Carthus great curved sword and its really fun. The only problem in PvE are the bosses/enemies with a high bleed resistance. I would use a weapon with build in bleed for PvE, as your rouge won't last through a level
a random youtube video about it
