A blood form in VAMPIR changes your character's appearance and adds stats and skills; you wear one at a time. Forms come in six grades, from normal up to mythic. Hero grade and above can be re-summoned up to five times with diamonds, each time more expensive, and you keep one of the results. Duplicates of the same grade synthesize into new or higher forms, and the collection pays passive bonuses on top of whatever you wear.

Grades and what wearing a form does

Grades in the Korean guide
GradeNotes
Normal, advanced, rare Entry grades; feed synthesis
Hero Re-summon opens here: up to five paid rerolls, pick one result
Legend Duplicates power the transcendence effect
Mythic Top grade; six forms in the synthesis table

Class-exclusive forms give a class skill when they match your class; common forms give a universal skill anyone can use. A separate appearance setting lets you wear the look of one form over the stats of another; that is cosmetic only, except for special variants the guide calls out.

Summoning and re-summon

Summon tickets are split by grade band and by class, so a "rare to hero" ticket and a class ticket pull from different pools; the probability page lists more than 25 ticket types. When a hero-grade or better form lands, you can re-summon up to five times with diamonds. The cost rises each time and you choose one result from the whole set, so stop when you see the form you wanted rather than chasing the fifth roll.

Synthesis and the point safety net

Synthesis rates published for the Korean build
GradeForms in poolRate each
Normal 20 3.5%
Advanced 30 1.2% (3.2% in advanced synthesis)
Rare 40 0.5% (2.125% in rare synthesis)
Hero 45 0.3333% (1.9556% in hero synthesis)
Legend 22 0.5455% (4.09091% in legend synthesis)
Mythic 6 1.6667%

Failed synthesis at rare grade and up builds points: 20 rare points, 15 hero points or 7 legend points exchange for a form of the next grade. Netmarble notes that the rates are rounded and may not add up to 100%. Treat the table as the shape of the odds, not a promise about your next roll.
