Rock Lee is currently the strongest character in the game in terms of damage output.
His base ATK stat is 2197 and he also has a very good HP stat of 1503.
His Ninjutsu is a single unit hitting attack with a damage multiplier of 3.2 meaning he does damage of 7031 before modifiers. This costs 5 Chakra so it a little expensive but worth it for the damage.
His Secret technique is a much improved version of Sasuke Uchiha's (Lone Survivor). It raises his damage by 150% for 10 turns and also charges his Chakra by 4 meaning he can perform a Ninjutsu straight away next turn. The only down side to this is that he takes slip damage for 10 turns and he cannot attack on the turn he uses it. His Ninjutsu after this boost hits for 17576 and can easily hit 20000 with either a critical hit or having a type advantage.
Range and Skills
He has a short attack range and also has the Field skill to counter attack just like Sasuke (Lone Survivor) and Neji (A Caged Bird). His Buddy skill also has a chance to boost your critical hit rate by x2.25 which is one of the higher ones in the game currently.
hey is there any other way to get this char, other than spending 50 pearls to summon, which doesn't really guarantee that he will get summoned? I think after a while grinding pearls become super difficult, especially if you have cleared the story mode (both normal and hard) and the daily login also becomes suckier cos currently I am on the 10+ days, which mean that i can get 5 pearls once every 5 days :(
This is becoming more and more unfair, imo (haha sorry ranting since all the 5 star chars that i've ever gotten are gaara, then gaara again, then gaara again, like, whut.)
