I hope you all forgive a couple newbie questions, I just picked this up over the weekend - familiar with gachas though
1) Is there any point working on 3* / 4* weapon tree unlocks or should I just wait until I can do 5*?
2) Do you usually switch characters when playing to activate each characters dragon, since they don't auto-activate?
3) is it worth using/leveling any of the non-greatwyrm 4* dragons, since the greatwyrms have tradeable unbinds?
4) What's my best use of elwater? Promoting the "main protagonist" since his final +20% exp seems real useful, or buy wyrmprints or something else?
I did a couple pulls on the bridal banner but saving my gems now for a better banner... Got B!Aoi and 2x Freiya (one of which is now my B!Xenthia dragon) though, so not too bad. Not bothering with elemental teams yet since I don't have enough exp lying around to level that wide yet.
Anything else I should pay particular attention to? The free 5* at the start I got was Nefaria which rounds out my current team.
1. Realized I just wrote some info without explaining basics, so I'll put that up here first. Notation for weapons is sometimes "x.y.z", where x = rarity, y = tier, z = unbinds. Sometimes the unbinds is left out (ex: "5.3"). If you see a "v" before that (ex: "v5.3") that's a "Void" weapon made from materials in special fights you unlock after chapter 7. They are elemental from tier 2 up instead of just tier 3, and have bonus abilities rather than skills. Elemental weapons actually have 1.5x stats on a matching element adventurer, and only matching adventurers can use the skill/ability on the weapon. There's no concept of additional/different elemental damage when the adventurer doesn't match the weapon, fwiw; that's all based on the adventurer.
Anyway... 3*s are ok for you at the very start. 4*s are not bad either, though you will want to use 5*s long term. There are even 4.3s used over 5.3s in endgame fights in some cases due to the skill (though the alternate Void weapons made from different materials also compete with that now). You will be limited in making 5*s first by needing your level your facilities, then by the material Twinkling Sand that's from events(/Gauntlet now), but making 5.2s for people to share is a decent short term goal before you start thinking about 5.3s for your best units.
2. Dragon meter is shared across your whole (personal) team. So there's no point in switching after activating it on your main; they won't be able to use it. The only exception would be a case where you want to use a certain dragon's skill but not have your main transform, so you'd switch + transform + switch back, but that can be very tricky and waste a lot of time due to the AI being in the middle of things when you switch. So... generally speaking, nope, just stick to your main for transforming.
3. You will absolutely not be using the greatwyrms long term, actually; their auras (the buffs from equipping them to a matching adventure) are very weak even compared to 0UB (this is notation for 0 unbinds, MUB being fully unbound) of the gacha 4*s. Only one I'd care about using in the short term is Brun, I guess? She has a pure strength aura. Generally you want pure strength on melee, pure or hybrid on ranged, HP exclusively on healers. The newer dragons have been having weirder auras, but they usually more or less map to the strength/hybrid/HP types still.
So you can use the greatwyrms for now if you need them. But I would not go out of my way to invest in more of them unless you notice you're really really not getting any gacha 4*s in some elements. And for the elements with hybrid or HP wyrms, you may be better off even using a 3* with a pure strength buff, if you have them.
So generally speaking, 4* gacha dragons will actually be what you use the most as things are currently. Because dragons only improve their aura at MUB (compared to prints, which were updated to improve their abilities a half-step at 2UB), a MUB 4* dragon is better than a 5* with only a few unbinds. And it's far easier to end up with a MUB 4* than multiple of the same 5*, especially as they've been making it easy to get a lot of the 4* dragon unbind item lately. Though, along those lines, don't unbind a dragon using a duplicate if you can still actively use the dupe! Much better to waste the exp on leveling the dupe to use currently and unbind using it later, than to immediately unbind only to have nothing good to use on the rest of your team.
4. I would save your eldwater for now. Because you're playing with no prints in the gacha and during an event where the event print is healer focused (rather than for skill damage/strength), I think getting some prints to start off with (I would only recommend a single copy of them for now though) will likely be the first use of your eldwater, I think? But even that I would hold off on a bit. See what you get as drops in the short term, then I would ask us for recommendations with your eldwater budget.
In general, 4*s are completely fine as 4*s. The 5* promotion is really not as inherently significant as it seems, and some don't even have good abilities in the fifth circle anyway. That's a thing to consider when you have things much more figured out and have the understanding required to know if it's worth doing. Especially given what I just said about not having gacha prints.
Regarding Euden... the better exp buff is not all that important. I've never gone for promoting him nor paid for energy refresh, and I'm level 135 of 150. Events will sometimes give prints that give you the 15% buff so you can run anything and still have it, so you'll mainly be using one of those instead of having Euden in an off-element team anyway (they don't stack with each other or with Euden, to be clear). I'm guessing we'll be seeing one of those for some summer event (I think preciously it was Christmas/Valentine's?) given the influx of players lately. I'll say he's not bad in general, so there are worse units to promote, but I would not recommend spending thay on him so early on and definitely not just to get the buff.
Beyond that, random tips... I'll try to think of some later. We could stand to do a FAQ or something for new players, maybe. Big thing off the top of my head, since you mention playing other gacha- do not use 3* prints/dragons as fodder! The exp is extremely extremely small (I think a 3* dragon = like 3 or 4 of the basic fruits) and selling them will instead get you some eldwater, so at least do that. You won't lose any money/water from unbinding them first (it'll just multiple what you'd get appropriately) either. But early on I'd keep those around as you might actually want to use them. Heck, I wouldn't even use lower weapons as fodder once you're a little later on; you'll get so many whetstones as drops that you can't possibly use all of, so it's better to use some of them and sell the extra weapons. But for now, 2*s as fodder is fine.
lower level weapons have a point, even if they are replaced by better weapons; i run with the 4* healer staff cause it has a third healing skill, as opposed to the 5* which has a boost
the best dragons come from summoning, and are the ones that give a bonus to _strength_. there are lot of nuances there, but the 4* strength dragons will be your workhorses for a good while
euden, the protagonist is ok. dunno if you want to promote him right away tho, although the exp bonus is nice
don't spend wyrmite in anything that's not sunmoning or buying the wyrm workers for the halidom. or MAYBE completing the event building so you can complete it in time
dont continue or use wyrmite for the daily item summon
Only takes 4 days of constant building to make the event building, they still have time. May be cutting it a little close if the ending times happen overnight/they're not on top of it, but I'd try to get all the materials first and then see if you need to rush the last few levels. May or may not be worth it. Actually- are there even any endeavors for leveling it this time around?
ah, wait, if you just meant to help with the challenge battle... I don't think they'll likely be strong enough/have enough resources so early on for that to make a difference at all?
