Double Thunder Bolt
Each hit deals 3000% of your hero’s MATK as thunder damage at level 0, and each level adds 5% for every rank the skill has. It hits 2 times with each cast. It casts every 0.5 seconds before anything speeds it up. It costs 30 MP a cast, plus 2 for each level. It can leave what it hits with Electric.
57 of its levels give lasting bonuses, from level 5 up to level 2,000 (see Level bonuses). The first is 10 more MATK.
Rank costs
Ranks go up to 50 at first, and the Dojo’s own ranks raise that to 200. Each rank costs 7.94328 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.
