Leech Stacks bug

[run4cuvr]

First, thanks for an awesome game, I've been enjoying it a lot. Here's where my confusion currently lies

Now, first off, I can only give so much information since there is not currently a setting that shows me how much damage I take numerically per hit, no healthbar numbers, or anything like that. But, I am using the Parasitic Stone, first on the iconoclaust then the axe and dagger. I seem to be accruing infinite leech stacks. My current counter is at 96.

For context, I only get stacks when killing with melee (expected behavior). For a damage comparison (this is the best info I can give) I am using Tiel and am level 7, meaning 71 health +19%. I went to the singular shield enemy near the first beacon just past the trial, and when he hit me with an overhead strike with the shield, he took about 1/6 of my health bar, so I'd approximate 14ish damage IF I have no bonus health. I don't know how that aligns with what the current damage output is expected to be from that mob.

Additionally, resting does not reset that number. It just continues to climb. This of course could be a purely visual bug and Leech is working as intended, or I've encountered a bug that would let me farm kills and become a god amongst men with a nearly infinite healthpool. Though, this is hard to tell since nowhere is there a specific description of what leech stacks actually do. I believe they're supposed to increase your max health, but by how much? A raw number or a percentage? if I could see my actual health numbers I'd be able to tell more.

As a sidenote, one time I was poking around in mushroom village after this manifested and killed the accordion wielder near the entrance, then my entire hud disappeared. No healthbar or anything. The visual effect when low on health still functioned. I was able to fix this by simply restarting the game.
