lol, what's she like in this?
She's just kind of a jerk.
Oh, and I thought I'd mention this so people would have a better idea of the mechanics or what they want to do about transfiguring or stacking.
Transfiguring is not like evolving in Pokemon; if you transfigure it does not mean you are necessarily getting stronger. On each Mirage's Mirage Board there are two types of nodes, normal ones and ones with little curly stuff around it. The normal ones are nodes that affect a Mirage REGARDLESS OF IT'S TRANSFIGURED STATE. So if you get a Strength + node, in every Transfiguration it will benefit from the Str+. Likewise if it is an ability or passive, a transfigured Mirage will know that ability/passive. The ones with curls around them are SPECIFIC TO THAT TRANSFIGURATION; these are all abilities or passives and only take affect or show up in your ability menu if you are in that specific state.
The most important parts to take away from this are:
1. You can buy nodes in a Mirage Board for a transfigured state even if you didn't turn your Mirage into it simply to make your Mirage stronger or expand it's abilities or get a Mirajewel or whatever. For example, if I want to keep my Sharqual a tiny lil shark but want to bump his stats and have unlocked the Mega Sharqual Mirage Board I can start going through that board and buying nodes to power up my tiny Sharqual.
2. Transfiguration is mostly strategic in nature. Transfiguration is about adaptability and preference. If you want more Medium Mirages you can Transfig a S to M or L to M (depending on the Transfigs available) to have a stronger stack. Or if one Transfig has better resistances or abilities for the area you're in or a Secret Area Mirage you're trying to capture, Transfig to the form that has better resistances or elemental weaknesses. Or hell, if you simply like one form better than another, just use that form and clear the other boards when you can so you don't have to worry about lagging behind.
3. I am about 80% certain this is the way stats work; there is a base stat value for a Mirage which is then modified by the Transfig it currently is in. So if let's say a Mimic normally has an 80 for Str, maybe a Magic Jar Transfig adjusts it by 40% while a Mimic Queen Transfig adjusts it by 120%. If this is not in fact the way stats work, then I would assume stat gains are based upon the star rating of each Transfig form meaning that whatever Transfig it is in dictates how much each stat increases. All this means is that you can choose what stat is more important for the skillset you want a Mirage to have and keep it in that form accordingly while clearing it's other Mirage Boards.
Hopefully that helps some people.
Honestly, I'd say that transfigs give you more options and some may be inherently stronger just due to greater stat Star Ratings or more diverse abilities (mostly because they're unlockable through Mementos) but it's not the majority. Hell, I got Mist Dragon after Holy Dragon and Mist Dragon is a fucking Evasion Beast and smaller than the Holy Dragon.
