[iHATEvideogames]

i've already played all of fargos eternity mode, already have played calamity and waiting for infurnum to be finished, so whats some reaaaally hard mods for terraria besides these two?
(i just realized i put calamity instead of terraria oopsies)

Play mod of redemption when its out (later game is kinda hard as in later i mean post plantera)

For 1.4 i suggest master mode and the for the worthy seed if you want a increase in difficulty
the for the worthy seed makes it substantially harder beyond increasing the damage and health of enemies

eh ftw master mode is just a health and damage slider, i mean sure the bosses are slightly tweaked in ftw but thats just like the size or skele prime's bombs destroying stuff

i just smash together as many mods as i can with it still being "possible"
