HOW MANY BLOODPOINTS ARE NEEDED TO GET FROM LEVEL 1 TO PRESTIGE 3 LEVEL 50?

6.4 million for p3 lvl 50, if only getting all cheap things on the bloodwebs, 14+ mill if you want all the perks after reaching p3 lvl 50. Mos people will have around 40-50 perks by P3 50 at R1 minimum, there are 65 survivors perks and 57 killer perks. with an average of 60k per bloodweb from lvl 45-50+ it'll take survivors around 145 more bloodwebs to get all survivor perks at R3. 60k x 145 = 8.7 mil, + 6.4 mil = 15.1 mil. If you want to max all survivors 17 survivors that's come to 256.7 million. as for killer it'll come to around 13 mil per killer for 15 killers, so 200-ish million.

This grind is massively alleviated in time it takes every 2x bp weekend or event, so if you are looking to rank up/max out anything quickly, wait for one of those weekends, in the meantime, getting the initial 6.4 mil to get P3 LVL 50 is best done by using a character with all of the bonus BP perks, and as many bp boosters as possible. If done right and pouring all of your bp into the character you want P3 lvl 50, you can achieve that amount in 120 matches or less assuming you get over 50k per match. Each match taking an average of 10 mins means somewhere between 20-30 hours of game play time realistically, So about 4 and a quarter hours of play per day for a week to achieve the p3 lvl 50 rank for a single character, and Maxing them out will bring that to about 90 hours of play time.
