I think nethers are currently to weak compared to normal creatures. Here is a little experiment I did:
I summoned an Unguided Amaranth nether with a white orb and 2 activations in red, yellow, green and blue with 5 level 10 gems each.
Stats for the nether where:
I also summoned a normal Unguided Amaranth with the following stats:
Then I took both to my highest realm level and fought a major sigil with XP boost. Both amaranths got 560 million XP leveling the normal to 324 and the nether to 151.
Stats for nether:
Stats for normal:
It seems to me that the normal wins on overall stats. Since both would face enemies of the same level the nether is simply worse than the normal creature. Furthermore using diamond gems is not only useless but downright damaging. You trade stats to level your nether faster which only makes enemies stronger in comparison to you (since you traded in stats).
I have two suggestions:
- Use a nether without diamond gems as the baseline for enemy level. Any XP gained from diamond bonus should not count towards enemy level and rather be an advantage similar to other stats.
- Use only 80% to 90% of a nethers experience for enemy difficulty. This should give balanced nethers an advantage over normal enemies. Right now the tutorial nether would be weaker than its normal counterpart.
