Spell that causes bleeding.

[Brogue The Rogue]

One of my players wants to create a spell that causes 1d6 bleeding each round. There don't seem to be many spells that cause this debuff effect. Any advice on how to stat this out?

Here are some of the better spells I've found that relate to concept. Any help you all can give would be appreciated.

Some bleeding spells:

Spoiler:

This high level bard spell does some damage and bleeding to multiple targets, but this makes it kind of hard to properly assess what it should be for just one target.

This Horror Adventures spell requires the spellcaster to maintain the bleed on themself and has a duration. I don't mind forcing the player to have a fixed duration, but they would, ideally, like to not have a duration. I could go either way. I understand the inherent power increase in allowing a player spell that gives bleed with no duration when monsters have less access to healing magic than players.

This Symbol spell might allow for some legwork to figure out the "level" of 1d6 bleed if enough legwork is done to cross-reference all the Symbol spells against each other with all their various effects, but at a glance, it seems too low to me for it to work. Maybe I'm just not familiar enough with them?

This touch spell only causes 1 bleed, but also causes exhaustion, has a duration, and is only level 1. That's a lot of debuffs for a first level spell, and seems a little beyond the scope of what the player is looking for.

Anyway, again, any help would be appreciated. Thanks!

Not quite d6, but 1/2 CL. Brow Gasher does require casting the spell and then hitting the enemy with the target weapon (note, the save is for the weapon, not the enemy). Cumulative attack penalty (and eventually miss chance) until they remove the bleed. Level 2 for classes that can cast it.

Blood of the Martyr is closer at 1d6/4 CL... but the healing effect is only if the primary target is willing or helpless. Levels 2-3 for classes that can cast it.

Bone Flense is similar to Brow Gasher, but targets the enemy. The bleed is kinda incidental, as the main draw is adding 1d6/CL (uncapped) piercing damage to every hit the target takes in an organized party. 1d6 bleed for CL/2 rounds though.

Rend Body I can bleed... but I mean, you've ripped off their limb at that point so why bother with bleed.

Litany of the Red Crusader adds bleed 1/hit to the enemy that stacks, but only lasts 1 round. It is a swift cast though.

Burning gaze causes ongoing damage (if not bleeding exactly) and might be a close parallel to what the player wants. If it did physical damage I'd up it a spell level.

I immediately regret not listing all the spells you listed, Firebug. xD I did find all of those, but discarded them for various reasons. For example, Brow Gasher requiring the weapon makes it too difficult to model a direct spell off of (the player wants a target spell, I.e., pick a target, they start bleeding), so this spell makes a poor baseline for that effect.

Blood of the Martyr is just so complicated and has so many other effects that it would be hard to disassemble with accuracy, I think.

Bone Flense has the weird society specific stuff that always messes with spell levels, and I just don't want to mess with that.

I had your same thoughts on Rend Body. The bleeding was so ancillary it didn't seem to matter.

And Litany spells tend to make bad baselines for spell creation.

@avr
I forgot to expand my search to burning. Burning is similar enough that I could model the spell after it. I'll do a search through for burning. Thanks!

Edit: Thanks avr, found a pretty much perfect baseline spell I can use in the example of Spontaneous Immolation. Thanks a ton. :)
