Thanks yeah i need to understand more about. When they say feeding a mag with certain Race/Class and Like would i need to create a say Ranger then level level up the Mag by feeding it then at a certain level trade it to my Hucast? I want to make a really OP mag that will take me to level 200 and be something my character will be proud of.
It kinda depends. The way it works is: for evolutions that require a certain class/gender/ID at the required level, it
DOES NOT MATTER who raises the mag up to the level before the level required (for future reference: 9, 49 (first time), and 99). What
DOES MATTER is that the class/gender/ID required be the one that causes the mag to hit that required level. So you can easily use any other class up to 49, but if you wanted, say, Ila for the third evolution to get Milla and Youlla (high-level Shifta and Deband for the user), and you're not using a type A Hunter or type B Force (based on the stat spread), you HAVE to give the mag to a type A Hunter or type B Force at level 49 and ensure that one of those two classes levels it to 50.
Here's a general explanation of how each evolution works as well as a couple examples to further illustrate what I said above (gonna use a few specific class/gender/id examples regardless of requirements, but simply to show whether or not they impact the evolution):
First evolution: This is based entirely on which class owns the mag when it hits level 10. For example: a Skyly HUmar (Hunter) that raises their mag to level 10 will receive Varuna. If that same Hunter raises the mag to 9, but gives it to a Greenil RAmar (Ranger) who then raises it to 10, it will evolve into Kalki instead.
Second evolution: This is based on 1) the mag's first evolution regardless of current class, and 2) the mag's highest stat among POW/DEX/MIND at level 35. The Varuna from the previous example could be moved to from the HUmar to the RAmar or a Bluefull FOmarl (Force), but it will always evolve into either Rudra (POW), Marutah (DEX), or Vayu (MIND) once it hits 35.
Third evolution: This usually varies, but it's mostly based on the class/ID of the owner and the mag's stat spread at the moment it hits level 50. For example, the Skyly HUmar (Hunter) will receive Ila (with M&Y) if his mag's stat spread is DEX > POW > MIND. The Greenil RAmar can use this same spread (though DEX and POW can be the same if needed, though this is only possible with an odd-numbered level in MIND) to get Kaitabha for the same benefit, but with an invincibility trigger at 100 PB (Ila has no trigger at 100 PB). The Bluefull FOmarl's Namuci can become a Bhirava (Pilla) if she can boost her mag's DEX above its MIND stat and keep it that way between level 35 and 50 (note that this example only works optimally because Namuci and the two other MIND-focused second evolutions give M&Y at level 35, meaning that anything else can fill the third PB slot). The ONLY exception to this rule is the unorthodox Andhaka and non-Hunter-raised Bana mags, as these require a Force (any ID will do), 45 DEF, and POW/DEX/MIND > the other two.
(One thing to note about the third evolution is that it can happen again at every 5th level, assuming the conditions for a different mag form are met and your mag hasn't yet evolved into a rare mag or cell mag. However, this change only affects what triggers are available and the feeding chart used. The Photon Blast you receive at mag level 50 is permanent, though I'd have to test to see if it's possible to still gain a third Photon Blast if, for some reason, you still only have two after your mag hits level 50. Unless someone can confirm whether or not that's possible.)
Fourth evolution (a.k.a. rare mag): This evolution is very specific, and occurs at level 100
IF your mag hasn't evolved into a cell mag (which I'll mention below) AND meets the requirements necessary. Not only does each rare mag require certain class/gender/ID combinations, but depending on the combination and the rare mag in question, a certain formula HAS to be met. For example, in order for the Skyly HUmar to evolve his mag into a Rati, his Ila's stats MUST meet the formula: DEF + POW = DEX + MIND. Alternatively, if the HUmar wanted a Sato, he could instead boost his mag to 5/49/45 at level 99, give his mag to the Bluefull FOmarl, and have her level POW to meet the formula DEF + DEX = POW + MIND. The Buefull FOmarl can get a Sato of her own if she can get her Bhirava to 5/XX/45/XX, where POW + MIND = 50.
Cell mag: This evolution...works a bit differently from rare mag evolutions. Both evolve from third-evolution mags (with certain exceptions for cell mags), and both have specific requirements for their evolutions. Where cell mags DIFFER is that each form requires 1) a specific mag (and/or other specific requirements) and 2) the appropriate mag cell. For example, the Angel's/Devil's Wings mag require a level 100+ mag (
must still be in its third evolution) and a Heart of Angel/Devil. For the Stealth mag or Agastya mag, you need a level 50+ mag and a Stealth Kit or Liberta Kit (both of which, by the way, can be earned at the end of the current season by getting a seasonal character to level 40 and 80 respectively). Certain cell mags are even MORE specific, requiring certain mag FORMS (ex: the Hamburger cell mag requires using a Kit of Hamburger on a level 50+ Kaitabha, such as the one that the Greenil RAmar received in a previous example).
Hope I answered your question, and I hope the extra info gives you a better understanding of how mag evolution works.
It has always been possible to get a third Photon Blast belatedly by evolving your mag into something else if your evolution at level 50 learns a Photon Blast you already have.
