Terraria 1.4: Master Mode Summoning Build

Terraprisma – this item is going to be you’re main source of damage; and, essentially the backbone for this build!

Kaleidoscope – this item is going to help increase your LUCK chance! This is very important if you’re aiming for quick and clean boss kills.

Stardust Armour – this should be a pretty obvious choice. Stardust armour handles
exceptionally well in Master mode and even more so for boss fights!

Empress Wings – these wings can be interchanged with your wing of choice; however, I strongly recommend these as they seem to be the most sustainable.

Soaring Insignia – not only does this increase mobility, but it also allows for unlimited flight!!!

Necromantic Scroll – this increases you minion damage by 10% and lets you summon an additional one.

Papyrus Scarab – increases summon damage by 15% and lets you summon an additional minion.

Pygmy Necklace – increases minion slot by one.

Summoner Emblem – increases summoner damage by 15%.

Destroyer Emblem – increases overall damage by 10% and increases your critical strike chance by 8%.
