I think the problem here is that people are not considering that these are
supernatural abilities and
not spells.
Remember that Mark Blood, Blood Walk, and Burst Forth are
THREE different abilities and actions.
Blood Walk: Needs no person's blood to function. A BM can move directly to and through ANY living being that has blood without notice
seemlessly just by seeking the blood of a general target wanted. This is
NOT PvP this is not consent needed. Exiting a target is
painless by lore Tome and Blood, p. 52.
Supernatural 'Except where noted above, this class feature resembles the dryad’s ability to move from tree to tree (see Monster Manual, page 79'.
A blood magus merely designates a direction and distance (“a living creature twenty miles due west of here”), and the bloodwalk ability transports him to a destination creature as close as possible to the desired location. He can’t specify a named individual as the endpoint unless he has previously obtained a sample of that creature’s blood and has it preserved in a vial that he carries.
Mark Blood: Is
not a spell and NOT PvP directly it is actual physical collection of a blood sample from an individual. This can be based on DM ruling a specified amount is needed (vials/ rags/ bandages/hospital linens), quality (poured from a wound or bloody nose, gathered from slightly dirty floor of hospital, mixed with soil and grass from scene of a battle, wiped from the discarded blade of a dead foe (NPC: Orc, etc) whom wounded the target before death, etc), freshness (gathered in minutes, gathered when dry, stored in a vial for a week, stored for a year) [In the past DMs when asked have not made rulings].
This is all done in the aftermath of PvP while your character is dead, unconscious, bound, etc. (
consent is for the actual PvP) or by means other than PvP, like
ANY time a character bleeds and leaves blood with no consent needed (Injured fighting NPC, Bandages, any 3rd party that has access to a character blood, like healers, doctors,
barbers) for a bribe or discarded.
I have in my years on this server observed one single character RP, years before BM class was added, that he was concerned about his blood being used by evil and only did RP about this 1 in 50 times the character was injured. You players out there don't act like you even care about the character's blood being literally splattered, pooled and left every where you fight EVERY SINGLE DAY. Making an affront and requiring ooc consent to gather blood is not reflected in your actual play, just vocal here...
Burst Forth: THIS IS ACTUAL PvP and
DOES require consent EVERYTIME.
It does NOT require an individual's blood. A blood mage can burst forth from any nearby target with usually a Fortitude save (sources differ).
Posters here don't seem to be making the distinction that there are
multiple abilities and methods of use. Please stop addressing all your ire and fears that some BM will burst forth from you without consent...
PvP requires consent BY RULE (not specific to BM). Burst forth is but one aspect of a BM abilities and by hamstringing all blood walk type abilities with ooc consent you are
crippling all the other interesting aspects of blood mages RP and fun.
I shared all of this in earlier posts in more detail.
