Homebrew Demon Species Details

This is for those who seen Seven Deadly Sins these creatures have powerful powers the creation of black flames and the lack of pain receptors they also have transformations like the basic markings of the demon clan as well as manipulation of darkness these markings protect you from taking to much damage as help you not feel any pain but your body still retains the damage, another transformation is demonic contract which demons sacrifice multiple heart (Note: demons have multiple heart higher up demons have at the max 7 hearts) to become a being of mas destruction this will kill the user once the time limit of the form hits, now time what you all want Assault mode this form can be achieved a high level of strength  this will allow you to gain massive levels of strength to manipulate your darkness to crush your opponent literally and figuratively this amount of strength comes with the lost of emotion and the sense of right or wrong all you want is to cause death and despair and want to see your opponents suffer, Demon king basically god but if you cannot control the form your character loses control but if you can you can basically just destroy your opponent. Now for the levels on the demon markings/ Transformations the starting demon marking you get at level 10 (you the one Meliodas shows the first time) then berserk mode at level 20 then you can go to demon mode 2 at level 30 which is basically like how Meliodas looked once he got his full power back next demonic contract which is level 50 this one of the transformation that you can be stuck in if you choose you gain no more transformations after that if you transform in it so you are warned, next is assault mode which the level to gain this form is 70 then last but not least demon king to gain this level 90. Now for the skills these come with  the forms, first enchant hell blaze level 10, full counter magic level 20 (basically you launch magic attacks back at the enemy with double the strength), level 30 you of course get corrosion  which is basically poisoning your enemy with miasma and you will also gain Full counter physical (it's like the first full counter but with physical attacks), level 50 you will gain vanishing counter (This counter just stops any magic attacks the enemy makes) then revenge counter (all damage done to you will store up until you chose to launch all that damage back to the opponent note that damage from party members count to for it store up to), level 70 skills 1000 divine cuts and dark sword as well as dark pressure the first two are as the name says it then dark pressure were you crush your opponents with your darkness, level 90 it allows you to break curses and remove debuffs and will also allow you to break seal off areas to enter.
