Maybe I should explain why I changed things more.

The aim with Deadly Venom is to give it some -ANY- interaction with items and mastery trees because you are missing out on so much interaction with a big part of the game! Just the option of buying tagging someone and seeing their armor crumble is something you miss out on now. Just like being able to counter healing by buying an (yes, it's still an item) to simply see the DoT preventing a Recall while Ex-calling reduces their healing... It's some of the things that the older twitch was able to do, but now can't...

The added duration is meant to give more up time on he stealth for the squishy AP twtich, I forgot to mention that I'd make it so that the stealth starts cooling down at the first activation, so having 600 ap would mean that it has an uptime of 14 seconds with a cooldown of 2 to get back into that stealth. It's absolutely necessary for a twitch that only has that 1 surprise burst and then lacks any form of real sustained damage to follow that burst up. Unstealth, hit, Stealth, peace out kind of idea.

The aim for Venom Cask is really to bring it in line with and  which both get an area of effect slow, with damage AND interaction with their mechanics. So adding damage to that skill is something that I'd add to the current twitch too. I did somewhat over nerf the early stack to get more late game stack, which I admit.

I did not even change anything to Expunge, I just lowered the stacks on deadly venom to 5 ;)
