Shadow Abi should be more more convenient to use in end game

[Sikers]

So one thing I really like about Wigfrid's skill tree is the way she can upgrade Elding Spear, from strong but clunky weapon, due to high crafting costs, to super convenient and easy to use in the endgame and I believe something similar can be done to Abi too.

 I've seen a some players complaining that Shadow Abi's buff duration is too short or that the murder action concept is unconvenient itself, with which I disagree, I think it works perfectly fine in the early/mid stages of the game The problem starts in the endgame where having to constantly catch a animals turns into tedious and unnecessary grind. 

The easiest way to fix it, would be just make so Cursed Vexation turns her into a Shadow Abi, for the time of its duration and potion recipe could be changed to require a Dark Tatters, so it's only avieble after the rifts are open, but I have slightly more unconventional idea. So currently if you catch spider possessed by Void Masque in to a trap, it just drop mask on the ground and give you normal spider, not only it doesn't make any sense since this spider should technically be dead, but it's also super boring. So what if we could catch a possessed spider instead and murdering them would extend Shadow Abi duration to some meaningful amount, or maybe even make it permanent?
