I am willing to learn how to craft just need some help thanks for anyone that replays to this post I greatly appreciated

there is no supppress implicit on helmets - this is a suffix. i suppose one of the temporal chains mods is lab enchant so pick a base with it and then spam the resist essences until you hit another res + t1/2 suppress and bench life or spam the life essence until you hit res+suppress and bench another resist.

for the implicit you spam ichors and embers until you hit the right ones. you can elevate them if you spam some of the high tier ones but its expensive.

that armor/evasion mod is inconsequential and on that note you`ll have better chances of hitting the suppress mod on pure evasion base.
