What are tiers?

[HARDSTUCK S2]

I was looking at the relic table and it doesn't say what missions you can get it from...Instead it says "Tiers"...

Are you looking here for the info, official drop rate website

That tells you which mission the relics drop from

[Zukabazuka]

You use a relic and it has 5 items on the reward. It will work on any void fissure. What you most likely are reading is the old system.

Each relic have different rewards, some rewards are on several of them.

Tiers are the difficulty of the mission. Every node is sorted into 1 of usually 3 (sometimes 4 tiers). So easy missions (tier 1) of the same type (like survival, for instance) will all have the same rewards, or the same chances at rewards.

"Tiers" indicate the general difficulty level/starting enemy level of the mission type in question. This may not be 100% accurate, but Tier 1 is generally missions you'd find from Mercury to Phobos, Tier 2 would be found from Ceres to about Saturn or Uranus, and Tier 3 missions would be from Neptune to Eris and Sedna. Void missions can be found in all of these tiers. Another general categorization (again, may not be 100% accurate) is that Tier 1 is missions with starting enemy levels from 1-15, Tier 2 is enemy levels starting at 16-30, and Tier 3 is enemy levels starting at 31-50.

In other words, the reason it's not telling you what specific mission(s) you can get a relic from is because all missions of the same mission type in the same "tier" also have the exact same drop pool for their rewards. For example, the drop tables of the Interception mission Berehynia on Sedna are the same as those of the Interception mission Xini on Eris. Different individual locations of the same mission type don't drop different rewards or have different drop chances for the same rewards, UNLESS they are also in different "tiers" based on starting enemy level.
