Ok, we finally found a decent connection to (ab)use, so here goes the criticism:

[hider=Shifter_Masters Alphonse]
Firstly: We’re tired of characters loyal to themselves alone. A true mercenary is better than a mere loner, but still its something we would rather avoid. Perhaps you should try him actually working for someone from the start? 
But that is a minor issue compared to the fact that you’ve essentially not integrated any lore into your character. With the two above combined, you have no reason to connect to anyone else. Not good.

Secondly: Assasssins aren’t complete misfits. The assassin that sticks out the way your character does (from non-physical traits) makes him a horrible assassin. We’d rather he has some sort of loyalty to someone. Doesn’t matter to us whether its Kalnach, Oragos, Idris or some other nation, just not another loner. In a medieval era, an assassin working alone won’t have the connections get both the information needed to kill high-profile targets or to get said jobs in the first place. Working for another nation’s throne (or some ambitious person near it), he would have all that. 

Thirdly… The relic:
You have multiple powers that have no logical reason to fit together other than to serve as an assassin package. Bloodcrafting doesn’t mesh with shadowweaving. And both of those are extremely powerful in the right hands. Scratch out one of those and add a means of feeding/fueling the relic, and you should be more compatible with this RP.
Also, the appearance of the relic is not conductive to him staying out of sight, which would in turn make him less effective as an assassin.

Then there is the fact that your relic also allows him to drain life. With those powers all combined, your character is exceedingly overpowered. 

Fourthly: You describe him as hating the relic. Unless he’s an adherent of the Order of Idris, that makes no real sense. And this would mean he hates himself, for when a relic bonds to someone, it makes him or her want to keep the relic, to use it. 

The only thing consistently good in this CS was the appearance.

Though short, its fairly balanced. For origin: maybe he’s from Oragos?
We really want people to have allegiance to one nation, faction or other.
Nothing major to criticize at this stage.

“Answers to no one”. Not good. We’ve got more than enough people already with no allegiance to anyone. 
[b]Relic powers:[/b] We think the relic makes her a bit too powerful in its versatility, but at least it is balanced out fairly well by having powers that fit well together. Try to reduce it to a few powers she knows how to use. Maybe you can expand it later. If you do that, we’d also accept that she can use the power more, as that would make her more effective in the long run. Maybe there’s one or two she’s managed to figure out, with the potential for others. Also, restricting it to three actions is not quite logical. Three lightning bolts is quite different in energy requirement compared to lighting three candles. We have no doubt that you can figure out a way to balance this without restricting yourself too much. 

[b]Flaws:[/b] These are good. We like flaws, and these restrict her well, just mind the suggestions above. 
[b]Skills:[/b] Considering Kalnach is a society where women are hardly more than property, these skills don’t make much sense. Education is something that they would not want women to have much of any of. Its gives them too many ideas, lets them think for themselves, and that simply will not do. Knowing how to resist unwanted advances, while unseemly of a woman in Kalnach, is something a noblewoman would know how to do. 
“She can outsmart anyone any day” is godmodding, no matter how you try to excuse it. Having her more wily than most is ok, but being perfect at outsmarting everyone is not acceptable. 

[b]Background:[/b] Fix the stuff above and update this in comparison to that, and we can see again. The lore for Kalnach may be adapted a bit to become clearer on certain fronts.

The lore on Kalnach was a bit unclear concerning

See criticism above concerning people only loyal to themselves. Not acceptable. 
[b]Relic:[/b] How large is the relic? Is it a ring? A bracelet? Something else?
Too powerful. Both illusions and mind control is way too powerful. Especially when combined with the ability to drive people insane. Sure, you can use illusions to drive someone insane, but thats a tricky thing to achieve. 
Pick one of the two, then build on that. Either the illusions, or the mind control. 

If you’re going with the mind control, it has to have limits. Either its hard to use for much on anyone, or its self-reversing shortly afterwards. I.e. you can trick someone into doing something once, but you can’t permanently change them. Driving someone insane should be a task that takes time, especially if its meant to be lastingly insane. 

If you’re going with illusions, then you can do all sorts of interesting things. We’d recommend having a limited range, though. And given the opportunity, you can probably still drive someone insane, but it will be tricky, as you have to convince them the illusion is real. The people may not all like evokers, but they still know they exist, so an illusionist has to be doubly skilled to not be outed as one and have his/her illusions ignored.

Having the concentration flaw on it is a nice balancer. Short-term blindness is also something that you can play with as an effect, but not sure if its necessary.

Whatever option you go with, you should have some means the relic “recharges”. Doesn’t matter how, but its something you should have. 

[b]Appearance:[/b] That appearance does not make sense. For one, its not something anyone would go out in public with in the middle ages. For two, its a dracula image, not a human. Evokers might have superhuman abilities, but they’re still human (more or less). Try again.
[b]Flaws:[/b] Needs to be reworked to reflect the above stuff, but there are some decent ones here.
[b]Skills:[/b]Why is he more agile? How did he become acrobatic? Where did he learn how to manipulate people? How did he learn to fight with knives?
[b]Biography:[/b] It may have been unclear in the lore, but slavery is forbidden and non-existent Kalnach. As such, you need to work this over heavily. 
[b]Personality/motivation:[/b] Again, needs working over due to slavery being forbidden.
