Restore health when hurting enemies

With pleasure!

If you want to make a discussion page for it, I'd be interested in hearing what you've got to say.

I've got more suggestions if you'd like to see them (I intended on posting them with my message below but it exceeded steam's 1000-word comment rule)

I'm glad to see that my comment was able to help and inspire change!
And i'm glad to continue giving my opinions and suggestions going forwards.

Had a playthrough with the newest patch, and it's definitely much nicer than before. the blindness immunity in rain and thunderstorms and lower sunlight damage is a welcoming change, though it's a little too lenient in my opinion for later game.
I can definitely understand why you wouldn't want to make the umbrella give sunlight immunity, it'd remove the purpose of blood vials.
If you want my personal opinion, I think the blindness aspect of sunlight exposure should be removed, or at least tweaked to where it's applied to you after a certain health pull is reached (maybe <50%?). It's an annoyance rather than a challenge. And to compensate, make the damage of sunlight exposure scale over time as the player progresses through the game? That way it's a constant threat for the player to look out for throughout their entire playthrough.

That is a client feature of Fargo's Mutant Mod and HP Awareness, check their configs and disable the Debuff Tray/Popups.

One of the immediat issue i have right now is the vampire effect above the player head, it's annoying, any idea who to remove it? Or is it a mod bug ?

A lots of potentials, it's been a long time since i was waiting for a vampirism mod, please don't drop it, you can ask other modder if you need help, the potentail is a total overhaul of the game. And i don't see why it would be incompatible with any mod ! (well maybe other dimension mods)

vampire，goood。but i hope theres more blood spell or something ,like blood spear……

at first i thought this was a modjam submission. but then read the description.

I'd love to see vampirism open opportunities to play a more life steal focused playstyle, beyond just the healing on enemy kills as that effect probably isn't really be useful for most bossfights.

Also, a sort of perk tree similar to how Skyrim handles the Vampire Lord transformation is in consideration, maybe someday when I learn UI...

Hm, for some reason the equippable variant does not prevent Blood Transfusion from ticking faster, but it does still prevent you from being blinded in sunlight at least.

Honestly, that's a fantastic idea, I'm not sure why I hadn't thought of that. The Blood Vial's primary purpose is to prevent sunlight burn, and I wouldn't want it to be invalidated by having an umbrella equipped. I'll have it prevent the blinding effect but it won't stop you from burning. You've probably noticed that the Blood Vial's effect ticks down quicker in sunlight, holding an umbrella will also prevent that from happening. Also yes, this will work with mods that make the umbrella an accessory, that's part of why I'd rather it not completely invalidate sunlight and Blood Vial's role in that.

A simple but very nice mod.
Played with vampirism on a new character for a few hours and it's a decent experience overall. The burning in sunlight mechanic can be rather frustrating to deal with at times, especially during very early game where surface exploration is made solely reliant on night and blood vials which always have a limited stock. Perhaps implement more methods to avoid sunlight burn? (e.g. holding an umbrella.)
I'd also love to see how vampirism is further built upon outside of just providing buffs during certain time periods.
It's great mod with great potential!

This sounds really fun for a true melee playthrough

Peak.

Sounds cool, I’ll have to try it out
