In case you don’t know what artifacts are for (probably the most asked question in the general chat).
Artifacts are mainly used for upgrading equipment (weapons and modules) from Mk3 to Mk4. Mk4 is the highest level and the MK4 equipment in the equipment view has a purple color.
Artifacts can also be refined to Iridium in your corporation and can be used to change the logo of your corporation and in the future it is supposed to be used to get a dreadnought …
Here is an overview on how many artifacts it costs to upgrade equipment in the various ship ranks.
| Passive Modules | 10 | 45 | 110 | 150 | 180 |
| Active Modules | 13 | 60 | 150 | 210 | 250 |
| Weapon | 20 | 90 | 220 | 300 | 360 |
Rank 1-3 = Tier 1, Rank 4-6 = Tier 2, Rank 7-9 = Tier 3, Rank 10-12 = Tier 4, Rank 13-15 = Tier 5
Here is now how many artifacts you need to spend per ship to fully upgrade them to Mk4.
| 1 -2 | 2A | 46 |
| 3 | 2A 1P | 56 |
| 4 | 2A 2P | 300 |
| 5 | 3A 3P | 405 |
| 6 | 3A 4P | 450 |
| 7 | 3A 5P | 1220 |
| 8 | 4A 6P | 1480 |
| 9 | 4A 7P | 1590 |
| 10 | 4A 8P | 2340 |
| 11 - 12 | 4A 9P | 2490 |
| 13 - 15 | 4A 9P | 2980 |
To show you the relationship of vouchers to artifacts here an overview on how many vouchers you need per 1 artifact.
| Passive Modules | 600 | 444 | 681 | 1000 | 1000 |
| Active Modules | 461 | 333 | 500 | 714 | 720 |
| Weapon | 450 | 333 | 511 | 750 | 750 |
Of course you need a lot of vouchers and artifacts to fully upgrade equipment to Mk4/purple. But this comparison shows you on how many vouchers you need to gain per battle in relation to how much artifacts you need to loot per battle.
Here is how many total vouchers you need per ship:
