Breeding Knowledge (Skill) · Incremental Epic Hero 2 Wiki

It casts every 0.5 seconds before anything speeds it up. As a buff it costs no MP.

55 of its levels give lasting bonuses, from level 10 up to level 2,000 (see Level bonuses). The first is 200 more HP.

Rank costs

Ranks go up to 50 at first, and the Dojo’s own ranks raise that to 200. Each rank costs 3.34965 times the one before, and much more from rank 51 on. These are before the Skill Rank Cost Reduction rebirth upgrade and the hero’s badge talisman, which both lower them.
