First of all, I suggest introducing into the game those artifacts that are initially scarce in the main version 3.1, in particular:
- for increasing experience, there are only 2 artifacts and 1 composite one. I suggest adding 2 more (for example, +200 experience units per day or +2% to experience)
- for logistics: there are 4 artifacts. There are no composite ones. I suggest adding 2 more and making 1 composite set;
- for resources (there is only 1 artifact - the Horn of Plenty), so I suggest adding 6 new ones + 1 composite;
- for health (there is only 1 artifact - the Ring of Vitality), I suggest adding 3 more and 1 composite;
- for mana, there are only 2 artifacts, I suggest adding 2 more
- travel spells - there are no artifacts, so I suggest adding new ones: summon ship, summon creatures from the garrison, astral gate
- rune artifacts - there is only 1, I suggest adding 2 more
- artifacts for war machines - there are only 2, I suggest adding 4 new ones and making 1 composite set.
