Nice mod!

I find it hard to think about playing Defect w/o this. This feels like it really fits and makes an already very fun interesting, and different character more so on all accounts so mission accomplished!

the lock-on mechanic does need some expansion in the regular game. However, this patch might actually give it a little too much lock-on. reminder that lock-on is basically an alternate version of vulnerable for other characters, it is good to have it, but stacking 10 stacks of it serve nothing.
With that said, i think other cards are somewhat fine the way the are; the only one im having a problem with is the power card "damage control", it is a bit too expensive, as well as does not serve a very consistence purpose: you have more than enough block to never even bother using it; getting attacked (not very ideal for act 3 and4) will just give enough lock-on for the entire battle.
overall: it might be ok card if it drawn from white noise or potion, but a very skipable card, not to mention now it also pollute the rare card drop as well.
Aside from that card alone, i still do thank you for expanding the lock-on kit of Defect since he is my favourite character to play
