Tactical Strengths & Weaknesses

Strengths (Pros)

High combo potential.

Very high damage.

All moves are multi-target.

All moves can damage enemies in Sea Events.

Very good for PvP if used correctly.

Weaknesses (Cons)

Cannot hit Blade users.

Hard to obtain, as the player needs both Tushita and Yama, both swords with 350 mastery to start the Cursed Dual Katana puzzle, which is quite time-consuming on its own. Tushita requires rip_indra True Form spawned to start the puzzle for it.

High mastery requirements.

All moves are Instinct Trickable.

A highly used sword, thus, very well known on how to counter.
