Drifter Stalker's Mark and Toxic Bullets behave differently despite having the same wording ("bleed damage")

[patrikk]

Both the ability and the item say "bleed", but despite that toxic bullets spirit damage is % max health and static, while stalker mark is current hp % and changes over its duration.

the ability description doesnt mention what type of damage it is, so a player would assume its the same as toxic bullets
