Damage increase

[Amix]

First, happy holidays to all.
So my question is, what should I do to increase damage?
Best sword? Any tricks?

Odachi and Kusarigama are considered the strongest weapons and outside of certain skills or playstyles, Living Weapon is a great way to clear high level content.

I mean which sword gives A+ or S rank. I invoked a player who did massive damage but first his health depleted. How to do that.

[Xuhybrid]

It's an Onmyo, i think it's either Carnage or something else which buffs your damage but you take damage over time. The only way to avoid dying is to have "Tenacity" on your armour. He'll also have most of his gear geared towards (Critical) stats.

First: Using soulmatch and have "+ attack" effect on every armor piece.
Second: Best single Katana right now for me is the one have + 30% night rain damage, but nothing is really the best one, they all depend on your playstyle and favorite skills.
My trick: Spamming Ninjutsu and Jutsu is easy mode.

HAPPY ♥♥♥♥♥♥♥ WINTER HOLIDAYS!

I mean that.

It doesn't matter too much what sword you pick as long as you get the Holy Trinity - Close Combat Damage +20%, Change To Attack [your main stat] A, Familiarity Damage Bonus A (on zero familiarity those would be +15%, A-, A-). I use Osafune Kanemitsu to get the most out of it with grace and all, but before that it doesn't matter much.
As for tricks... well, there are crazy buff builds and critical builds. Without that - just stack CCD. Graces, Kingo or Tatenashi, mix sets to get that 4-piece bonus.
