Rosalio/Playstyle Tips

In-Game Tips

 * Since various items can be used as Blunt weapons, Rosalio can quickly build up Mastery in the early game.
 * Clutch Hitter always has a risk of missing and using it could leave you at an Health disadvantage, especially if Home Run does not trigger.

General
Rosalio himself is very straightforward and easy to play. His passive Homerun increases critical dmg and works as it says very well without have to bother about it, and Clutch Hitter is simply an attack with increased chance to deal critical hit depending on how much HP he lost. You would use his clutch hitter in a clutch moment to make his attack get higher chance to crit.

For his early to late game phase, he dominates his start with his superior D+ Mastery on Blunt. Not many would stay with him trading hits when he has a higher mastery lead and increased critical damage. Doing so will just makes him even stronger because he has faster lead on mastery and he hits harder with it. This will ensure him he can get a good start for his early phase.

While at the late game, he still remain strong because his skill kit involves critical hit that is very game changing and would create a fatal situation when proc to enemy. You could try to raise your crit rate and dmg with accessories such as Pirate Flag and Dice of Destiny while building up your masteries to inflict even higher dmg. He's hard to deal with when he gets a lead and he always has a chance to severely damage you with his strong critical hit.

Counter
However there's a way to counter his strength, which is crafting Amazoness Armor that has a passive to reduce critical damage taken from enemy by 20% and Creed of the Knight that reduce damage taken from Blunt weapon for 10%, these two armor pair well back to back and it will help to counter Rosalio prowess significantly. Or for character specific, Hyejin's Omen will shut down Rosalio perks completely for the whole of Omen's duration, and not to mention Hyejin late game stat is way more superior than Rosalio. More or less, Rosalio isn't invincible and he can still be rendered powerless depending on how the game goes for him and getting outplayed by other people.
