Assassin/Ninja Help Looking For Improvement Ideas

I've got a bit of a spell-based water assassin that I'm looking to upgrade.

Sequencer (for spell damage)
Seagazer (for mana regen)
Clock Leggings (for spell damage)
Scorpio (because poison is overpowered)

Myrrh x2
Morph-Amethyst (for lack of better options)
Snowflake (probably going to change to Royal Stormy Amulet)

Alazarin (5 powders, 1 in each element to abuse elemental weaknesses)
Bob's Mythic Daggers (for neutral damage)
Rewind (2x tier 4 water powders, primary weapon, might change to Snowdrift at level 95)

I'm at level 90, but can grind to 91 if needed.
