Enigma is an interesting mod in the scene, it's a large generalist content mod, as you'd expect.
However, every mod has something that sets it apart from others
When I first started Enigma, I was not that impressed, the bosses I faced eariy on wern't that great and their music was, very quiet for some reason.
As I started to get further in I noticed Laugic started doing some pretty odd things I hadn't seen before, these include:
a damaging debuff which ISN'T a debuff
The timestop ability, not seen anything like it before, now I like to drive into a mod not completely knowing what to expect, so this was a neat surprise!
A parallel dimension which doesn't despawn but cleverly hides enemies, also the ore isn't minable outside of the Etheria, nice touch.
^Makes you want to fight old bosses again
I was doing a mage playstyle, so I didn't bother with the mysticism system, but it sounds really cool, far more original then what Tremor had.
Basically what I'm saying is some really cool and fun technical stuff, this mod pushes that alright.
Now, some cons:
-As stated before, the early game doesn't show off the best this mod has, I wonder how many people would write it off as a crap mod after fighting a large single sprite boss that looks lazily used (that being dune sharkron), and then put it down
-Yes, the Obsidium biome takes up way too much of my world. my world didn't have much of a jungle due to it :/
-This mod needs a final boss, I get Etheria Rematch is like, the last boss, but it didn't really feel conclusive enough (it felt kinda cheap tbh, the first fight was easy, the 2nd was like, your going to get hit constantly), you need something after moonlord like what Thorium and Spirit have. I got no idea what, just pitching the idea.
-At this point in time my accessory slots are filled with items I've spent the entire game building up to, I'm not going to use the etheria items, now if you made it possible to craft ALL the etheria drops into 1 super accessory I'd use that!
Geez big wall of text, well eitherway this is my tidbits after defeating moonlord while playing with a ton of other mods as well. I hope it helped.
