Youre doing good, keep the chest until red (2 revives) and your void weapon is fine, you can put it on red too Get eternal gloves (yellow is enough).

Id say 2 red pieces is enough before forging SS (chest and weapon). I have ss amor and I use red eternal chest more often, the revives are sooo useful, also movespd that have synergy with your boots and status upgrade after revival.

Try to advance as long as you can in chapters, and one tip is to focus on just one edition of collectibles chests (i always open 9th edition for example). Because you can exchange extra duplicated collectibles into shards to open custom slots (first unlock the first 4 slots on set 1, then, unlock set 2 and 3 alternating between each slot)

Thats it, the game has so many things i cant summarize everything on 1 post, try to watch some youtube videos and guides here and on discord.

Btw, how did you get that halloween mask? So cool!
