Compatibility is the same as regular vampiric thirst. Requiem supported if you use the ms leeches vampiric thirst patch from patch central this will take away the passives but leave you the unlocked ranks and expanded bloodpool and higher power blood abilities. This is for balancing as the requiem health bonus is still there if someone wants to make a version of the patch to get the passives by all means feel free all script files are included for editing through ck or other editor so mod it however you like.  This is primarily for my own personal use so updates will likely be infrequent. I am also still learning ms leeches scripts so more ranked powers are out of reach atm but all existing powers have been edited in script to scale with the new ranks unlocked. for instance in normal mod celerity lasted five seconds at max level and was very draining on bloodpool in this mod at the rank of elder it last 8 seconds and with your larger blood pool is less draining. 



Changes 

stages 6-8 are now unlocked for player character the multiply aging setting and mcm can help you reach them faster but you cannot set the days to one and reach them that way. for now while this mod is in testing reaching bloodkin stage 5 will rapidly advance you to the next tiers 6-8. 

Being blood starved has its upsides the beast is nearly free... high increase to armor hp and stamina the ability to run across water and powerful unarmed attacks allow you to imitate a frenzied vampire. Blood starved still prevents the use of blood abilities though as you are not really in control anymore.

All miss leeches abilities and powers scale with the new ranks celerity will last longer, bloodpool will grow, speed and stealth will increase,  and your vampiric drain becomes even more damning. Follows same scaling as miss leeches implemented in lower ranks.

Being well fed comes with a perk of its own you will take 25 percent less fire damage 150 down to 125 and you will have a mortal healing rate again potions and magic are still not effective or as effective depending on settings however.

Higher stages 6+ now have passive benefits for vanilla like natural armor and higher health and stamina.

Compatibility currently custom races are not supported, some may work but if you experience a flashing redscreen that does not go away and vampirism does not start this is typically the cause.

Known issue sometimes celerity goes on for longer than it should pressing wait will end it this was a problem in the original mod as well and is tied to scripting having many script heavy mods increases the likelihood of this occurring.
