How soon is soon? Like a year soon? Probably will take you longer than that as a brand new player.
Aim for full SR Assault Grid. HP weapons can go straight to fodder.The over-simplification of the damage formula is
BaseAtk * Assault * Elemental
Base Atk you get as you play and grow stronger, Assault comes mostly from your Grid, Elemental mostly comes from your Main Eidolon and the Support Eidolon.I am shocked that nobody has pointed out that there is a thread for this. Because everyone keeps asking.
Do not fall for the Andromeda trap, please. Yes, heals are great when you are new. But as you keep progressing, the less and less relevant they become. Until then, Cass heals are plenty good enough.
In general, you want Hercules since she offers you almost everything that you want from a Soul: damage output, fast burst generation, tankyness, a free EX slot and a Def Debuff (from her 1-Star/3-Star Axe). Shingen is end-game, but since Shingen is gated behind... well, probably more than six months of play now, that's plenty of time to use Hercules.Honestly putting 6 Rs is kind of a waste. In the last skill level you spend 30 points to gain 35. Is it a gain? Well, yes. But if you actively leech Guardians, you'll have all the R Grails that you could ever want. Where you can put 30 points to gain 60.
I personally only put 3 Rs into SR fodder, which is 30 points spent for 70 points.This was already covered by dreamlitz, but this only holds true for Managarmr and Anubis.There is no way that any amount of Exceed that he has would make any kind impact on him, at all...The problem with Discord is that there is absolutely zero peer review. The local MagicSpice happens to be there and bullshits the answers? Well, you're fucked.The encyclopedia in Sanahtlig's toolbox gives you a quick peek on all the upcoming events.
Notice that in order to use Solomon, you must spend 6+15 MP on her (6 points in Ability+, 15 points in her CD-reset EX ability) AND have her offensive Soul weapon. Plus, you're so new that it probably won't even help you. With or without her you'll probably 4-turn the first ~5 floors, and then floors ~6-8 will just be a wall to you.Older players will tell you no, but that's only because they already have all that stuff. That said, Epic Quests are a thing now. And Guardian Eidolons are better as main than anything outside of 100% Eidolons.
You should certainly still MLB Tiamat due to her superb stats, but after that...For Magnas? You eventually want both. Tiara set bonus is amazing, but only really hits the fan when you have 3-4 SSR Hime with it. But 100 Magnas + 200 Treasures for a 3-star Guardian is no small journey for a new player.
By the way. If you see yourself getting into Kamihime, you should still reroll into a P2W Eidolon. It may feel bad to drop everything you've accomplished so far, but what you have right now is simply nothing in the marathon terms of Kamihime. If you're still playing one year from now, you will be sorry if you didn't reroll. You have been warned.
