Legendary Island as Archer

Hello,

I have recently tried beating the Legendary Island, and failed horribly at already the second boss. I almost brought him down by running around with my lvl 105 trapper, throwing bombs from far away, but then got one tapped, even with 14k health.

My build is:
Morph Stardust
Libra
Aleph Null
Steamjet Walkers
Intensity
Draoi Fair
Stellar
Freedom

I watched people using very similar builds on youtube. They have some different items, such as Stardew, which might be a little more powerful, but they don’t seem to struggle at all, just walk up to the boss and basically spam arrow storm, while what I had to do was circle around and do minimal damage from bombs. What could I be doing wrong?

My build IDs are not perfect, but they are above average I would say. I just don’t understand how I can have such a similar build with completely different results. Please let me know what I could improve.
