Companions scaling

[geor_chri]

Hey guys, decided after many years to do a full run on ds2 (never reached elite difficulty). But before I start I want to know how the companions scale during a playthrough.
For example, if I recruit a follower after normal difficulty(veteran) -like finala- will she scale correct with her stats? Wiki says that at veteran she is at 50 combat magic. But with the same equipments and skill points will she be the same as if i had her from normal mode(22 level) stat and damage wise? Or having her from the start gains more bonuses from fighting?
Also blood assassins are worth it? Never tried one. Sorry for the strange question but couldn't find a clear answer and I always liked to min max this game even if it's single player :P

You have 2 options about your companions: if we are talking about Finala, she is in lvl 50 when you pick her up in Aman'lu in veteran, or you can pick her up in normal dificulty and drop her at the inn at lvl 22. when you picke her up again in veteran, and if you are 20 lvls above her (lvl 42), she will scale to your lvl -2, that is, lvl 40 in combat magic, with all the skill points, and the equipment she had when you left her at the inn, imo this option is better bc you can have the extra skill points from quest from the start, and you can have her from the start, and fighting with her from the start will make her catch up with your lvl much faster.

About assassins, I am currently playing with one, (2 actually, my main and Ressa) and its pretty fun, but I think the assassin class is much better when u use thrown weapons (richochet triggers shred blood and bleeding), and the repulsion enhancement.
