About this converter
Skill credits in Blue Archive follow fixed ladders. EX skills run 80k from Lv1 to Lv2, 500k to Lv3, 3M to Lv4 and 10M to Lv5, for 13.58M total. Basic, passive and sub skills share one ladder. Steps run 5k, 7.5k, 60k, 90k, 300k, 450k, 1.5M, 2.4M and 4M, for 8.81M per skill and 26.44M for all three. The last EX step alone costs more than the first three combined. The last basic step needs 4M plus a Secret Tech Note. Credit numbers stay the same for every student. School Blu-rays, Tech Notes and Ooparts differ by school, so Hyakkiyako costs stand in as the material example.
How to use it
Pick two entries and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. One box holds a count of the first skill step, one holds a count of the second, one holds credits. Try 1 EX Lv4 to Lv5 against Basic Lv1 to Lv2 to see 10M against 5k. Click a table row to load that step as Entry A with amount 1.
Credits only. School Blu-rays, Tech Notes, Wolfsegg steels, Mandrake parts and Secret Tech Notes ride in context but do not change credit values. EX totals 13.58M per student. Each basic skill totals 8.81M, so three basic skills total 26.44M. Equipment tier fees are left out for scope. Unique weapon ranks and Mystic Eleph costs are left out. No figure here is guessed.
