I think it was like 1.35 maxed king metal minituars to get them to 110, and then another 9.5 to get them to 120. Someone on the FFBE board posted about that yesterday.
Might as well post this.
As always, varies somewhat between units do check before you dump full kings.
Level 120 And Your 7*s
Leveling 7 star units to max level is veeeeery heavy on the experience requirements. Going from level 101 to level 120 costs 45 million experience, or 10 max level King Cactuars.
I can't speak for everyone, but in my case, I only *have* 10 max level King Cactuars - and I have a lot more than 1 potential 7 star.
I was struggling to decide how best to level them, when I decided to take a look at the experience chart.. Take a look:
* **101 -> 105**: 1,702,194 exp (~0.35 Max King Cactuars) * **101 -> 110**: 6,732,534 exp (~1.5 Max King Cactuars) * **101 -> 115**: 18,706,384 exp (~4 Max King Cactuars) * **101 -> 120**: 44,653,250 exp (~10 Max King Cactuars)
As you can see, there's a VERY large exponential growth in experience cost the closer you get to 120. So, what am I suggesting?
While I can't speak to later batches of 7 star units, the one we're looking at now (disclaimer: this is before any GL-exclusive enhancements are revealed) gives all units their strongest/core 7 star abilities by level 110.
Level 110 is easy to reach - you can get 6.5 units to level 110 for every unit you can get to 120. That means you can build a full team of level 110 units at the cost of a couple of weaker passive abilities for one unit (and some base stats). Those last 10 levels provide different benefits for each unit, but typically include one small, weaker passive at level 115 (most are 20% MP, 20% SPR, etc), followed by a mid-power level passive ability at 120. While these are certainly useful, if you compare them to the abilities the units get at level 101, 105 and 110, they can't even begin to account for losing 5.5 other units at 110.
In other words - since we're just beginning to build up our well of experience to put towards 7 star units, distribute it in a way that will get you a solid team of partially leveled 7 star units at level 110, rather than dumping everything into a single unit!
(disclaimer: beyond the abilities, unit base stats rise as well, which can make a bit of a difference, but I'll leave that to you to value, as it's hard to put a precise valuation on the stat growth for all of this batch)
**TLDR:** Level a core team of 7 star units to level 110 first, instead of leveling a single unit to 120, as you can get 6.5 units (a full team) to level 110 for the same amount of experience as a level 120. Units get their strongest 7 star abilities at level 101, 105 and 110, so you aren't missing much, the 115 and 120 abilities are much smaller in strength, and simply nice to have, not necessary to succeed.
