Double Slash
Each hit deals 750% of your hero’s ATK at level 0, and each level adds 12.5% for every rank the skill has. It hits 2 times with each cast. It casts every 0.625 seconds before anything speeds it up. It costs 10 MP a cast, plus 1 for each level.
52 of its levels give lasting bonuses, from level 10 up to level 2,000 (see Level bonuses). The first is 5 more ATK.
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.
