PC How to add a debuff on equip

[Thingerthing]

Here's the idea I'm trying to do. I'm trying to make a weapon that's strong, but removes some health.

So I tried this first

        public override void UpdateEquip(Player player)
        {
            player.statLifeMax2 -= 75;
        }

Didn't work. Then I searched. Alot. I couldn't find anything like this as every search result I found wasn't related to this problem at all. So I'm asking you people.

How do I make the item I'm trying to make?

UpdateEquip is for accessories and armor but it sounds like you want it for a weapon. So try starting with this hook instead:

Terraria ModLoader: Terraria.ModLoader.ModItem Class Reference

That worked, but how do I take away health.

i've only modded for about a day

Do you want your weapon to drain health from the player or just want it to reduce max hp? Or just apply debuff?
First case :

int lifeCounter;

public override HoldItem(Player player){
    lifeCounter++;
    while(lifeCounter > 10){
        lifecounter -= 10;
        player.statLife--;
    }
}

This will deal 6 damage per second to the player. You can also
Second case :

public override HoldItem(Player player){
    player.statLifeMax2 -= 50;
}

This will temporarily reduce holder's max hp by 50.
Or you can just :

public override HoldItem(Player player){
    player.addBuff(BuffID.Venom, 2);
}

This will constatntly inflict venom debuff while the player is holding your item.
