Advice For Beating Legendary Island?

So after a long and rather fruitless battle attempting to beat the supposed easiest boss of Legendary Island, The Mummyboard, only to find out it has multiple phases and dying to the second, I thought I'd ask for help on the forums.

What's the best way for an assassin to tackle Legendary Island? Or best way to fight Legendary Island in general? I'll admit my build isn't the best in terms of high damage or health, a walk-speed centered storm ninja. I know people have managed to solo it before, but I can't seem to find a way of doing it myself without managing to find an entirely new build and reassigning all my skill points.

Spoiler: My Current Build

Helmet: Skywatcher

Chestplate: Booster Plate

Leggings: Dark Shroud

Boots: Dust Skaters

Ring 1: Uriel

Ring 2: Kaze

Bracelet: Relend's Refrain

Necklace: Autotomized

Weapon: Odin (T6 Air and Thunder Powders)

Skill Point Distribution:
0/76/42/0/76
(Agility totals 109 with added points)

get a better build or skill pots if you wanna cheese it

 

What sort of build should I go for? Or are max-level Skill Potions enough to just cheese everything?

 

@12nebur27 solo'd it with full normal gear and skill pots
but id recommend getting a new build anyways if you want to do higher level bosses

 

Thanks! I'll look into getting a more damage-centered build more suited for bosses. The fact someone managed to solo LI with just normal gear and skill potions gives me a lot of hope!

 

This build got me pretty far, I died on Cybel after I ran out of SP pots. Just make sure to put air powders and stuff on armor, it doesn't have very good air defense.

It's also double hive, which is a problem. I don't have any good alternatives in mind.
