So I've been playing this game for a while, and to my surprise, it was fairly solid; at first, I thought the strategy is slowly expand and then win(which I did won, because I did decently enough, but without powerful party to decisively win rivals), but in reality, you really want every day count - by exploring and fighting in portals as quickly as possible using a light fox scout(highest vision possible early on while also doubling as support)and a pegasus mount, while also fighting in daily/ranked arena, because that's what matters the most. You can also perform town tasks and as one of two female protagonists, do shows, but all of them, expect tavern missions give a terrible time scale and stamina wise amount of money, compared to what you can get from portals, and better yet, high beauty brothel strats, which I'll explain later.
And a bunch of things, both being tips and things that can be described as gameplay discussion and tactics.
For protagonists, only the first one can reach the highest individual power potential - the other two have to rely on items that increase their stats, not to mention being restricted to what their skills/stats offer, while also being flexible at what you need - either a fighter, support, or a all-rounder, not a summon based spellcaster or a nature based fighter/tank, neither of which can give a free turn for the entire team, which allows for very powerful one-turn victories. Or special mana drain/insta-kill/full heal and buff abilities later on.
In terms of time, the 30-day time limit is actually the best option, because at longer times, you'll experience worse scaling in terms of power - if you take too long, the alternative ending will be even harder - I had to fight level 30 guardians using level 25 demons and seraphs, but that's obviously only that one - the wasteland and final portal still has armies of 20's enemies, but the final boss is always level 30, no matter how early or late you are, however, I found a strategy for it:
One, you have to complete the succubus homeworld and kill the guardians, then give up the succubus for a another crystal - what makes it hard, if not annoying, is the fact that the familiar that is required to open the portal, needs 100 mana, which, combined with poor growth, non-unique tag which means it will die forever in permadeath mode, no genes, and reliance on skills like Focus and Blink to even be tolerable in the first place(only possible if you take the dexterity option), makes it very annoying in the first place. The guardians are no slouch, having great stats, but if you make your own one(more on that later), it becomes fairly easy - just troubling to get in the first place, that is.
Two, after completing the wasteland and the guardians, go to the crafting tab and click at crystal - you should see 4 recipes, of which only 2 matter: the mana spear and the crystal. The first one is a weapon that sets a victims armor to 0 on attacks, which makes the final boss killable without relying on spectral swords and using cursed daggers and other support weaponry, while the other makes the giant beast defeatable by removing its passives, meaning if you cannot kill it in 1 turn without time stop, you now can kill it, cleanly.
Obviously, those 2 steps already require a party that is strong enough, like demons(fighters) and seraphs(all-rounder casters), if you want a versatile party for late-game, not counting for specialized tanks and casters. Now people always talked about kitsunes, but in my case, I ended up not using them - instead I opted for a thing called guardian, which, if the succubus hybrid characters do not tell you already, can be bred, and you'll either get impure succubus that can be fused, or a pure guardian - their genes are as a result, not good, but using fusion, you can make a perfect one with all traits and genes you need before you'll begin the ultimate elite of the elites, that can have the highest level without unlimited modifier, but also the highest stats that make the final boss cry. I had a level 40 once, then a level 50 guardian on another run, both of which made many enemies including bosses weak enough to be killed in a single turn, while being supported with others to kill them faster - with spectral sword, and if they are magic based, telekinetic, you can deal the highest possible damage with those - and while fun, their growth process is rather...reliant on how many characters you have to sacrifice them in the right order, which means you have to start from the weakest to the strongest, which makes it very exhausting - I spent several hours just trying to see from what I have to feed it in the right order to attain highest possible power. Practically any other elite(including the main character)is getting outmatched solely by its existence.
You can have 2 guardians for a run in practice, by not giving the succubus in their homeworld, but since you really need the spear if you do not have spectral swords/piercing claws, it's pretty much mandatory. Not helped by not having the highest genes, and having to sacrifice trait fodders, if you have any first - just hope they won't have much growth or you'll miss on potential levels.
The seraph event, which is fairly uncommon-rare without raiders modifier, is practically impossible otherwise on harpies side, but if you end up not getting it because of how sparse the events are with raiders modifier, you can actually defeat it in the first non NG+ run, using the strats I just explained - get a strong party and you can quickly kill it - you'll get a 100% experience essence, 8 level up shards which are perfect for guardian with ancient power, if it has one, and a bunch of weak harpies that well...better off being turned in for a quest.
Before discovering the guardian, I had to rely on just strong characters and supports, but now I know - level the succubuses, make them breed, then get highest possible genes and best percentage traits and lots of growth fodder and now you have the character that can end any engagement in your favor.
...Expect equality modifier, because that was...fairly weird one - on one hand, you'll get a level 10 final boss, which is much easier but not so different considering you are also capped and HAVE to get a guardian to make it fair anyway(and with limited power because it can't go beyond level 10 either), while making anything that requires higher level things like king's quests and tavern quests unattainable - and also making every enemy with level lower than 5 to be at least level 5, which makes early game much harsher than I expected. And even worse, the seraph event outright becomes a nightmare in such case, because it still has 600 health and 100 damage, which is higher than final boss and its beast combined, having 50 damage 200 health and 25 damage 200 health respectively. Unless you use a guardian, because it's still mandatory for such things.
The only modifier that is more help rather than hurt is plentiful, because even though it doubles item value making buying items from shop less useful, it pretty much makes resource management an non-issue, because generally by late-game you'll often need food for quests rather than feeding your members, and buying one apiece per click is terribly annoying. And makes reaching objectives of the shop much faster, and if you have merchant job, quadruple the sell value of items - a 100 value item becomes 400 due to how modifiers combine, while you'll only pay 50% more to the shop when it comes to buy value. You'll have others like historic, intelligent, diverse and so on, but none of them remove annoyance completely(if not making it harder)like plentiful itself.
Remember when I told about the beauty strat earlier on? All right, let me explain what it is; it basically boils down to having 2 breeding partners: the siren/angler fish with mermaid/lymean genes, and a lymean/water angel with lymean/lymean genes - which if bred together, results in a angler fish, which has a base beauty of 100, which, considering how it rolls on average, you'll have no trouble getting a 150+ beauty character. Obviously, high base beauty and beautiful trait is mandatory on both, and better yet, albino/royal for maximum value - and since they are all spellcasters, you'll need telekinetic and bunch of other traits to make them good enough as recruiters and support fighters. Now the brothel is going to be full of nothing but those things, raking in money that only one can dream of, especially if you use a profession that effectively doubles its profits. Expect maybe the plant madam, because she apparently collects materials while working in there as long she's recruited. And unique characters, because once you'll make a party that outmatches them all, what else they are good for expect the certain ones like the necromancer fish? I miss using them though, because of how fun their unique skill combinations they have, or the fact they are different from normal ones, like a succubus hunter which also the only one with both sniper/quickshooter combo, or a lightbug that is extremely fast at draining mana and fighting head on as one such examples.
I even speedrun the ending before getting the otherwise normal one in a 30-day setting by getting lucky with an artifact portal to have enough events for the special character in a single run to allow to make the special portal and then complete that one and surrender her because of not having strong enough party to fight the boss.
Well, I explained a lot of what I discovered in the game(for the current patch), including bugs and suggestions that I think, as long people tell where I should post them for potential approval, I would be grateful. Can't wait for a content/balance update and bug fixes. I would like to write a good review, but I think I should wait till it releases.
