Enhancement guide
1. There is no difference in stats if you enhance it at lower or higher levels. The end result at S grade level 50 will still be the same
2. The level of the monsters that you are enhancing into you main monster affects how much it will enhance your main monster by. But only by a little bit. So if you level up your monster a few levels, it is slightly better for enhancement.
3. The grade of the sacrificed monsters used to enhance also matter. A higher grade monster will give a lot more stats to the monster that you are enhancing as compared to the usual E- grade. However it is not advisable to enhance monsters to be used as enhancement. You will waste more silver and monsters this way. The only time to make use of this is if you really feel that you aren't going to use a certain monster that you have already enhanced ever again.
4. Slimes such as Sercurity, Snappey, Speedy etc give a huge boost to a certain stat when used to enhance. It is advisible catch to these slimes for the fastest and most seal card saving way. Here is the list of the stats that they boost:
Snappey- ATK
Sorcecery- MATK
Speedy- SPD
Sercurity- DEF
Safety- MDEF
Superiority- All stats
If you were to use slimes to enhance, and slimes only, here is how many of each type you would need to go from E to S grade for a single stat:
Commons: 2 of each type (86010 silver for each stat)
Uncommons: 2 of each type (114680 silver for each stat)
Rare: 2 of each type (143350 silver for each stat)
Epics: 4 of each type (286700 silver for each stat)
Legendary: 12 of each type (573400 silver for each stat)
5. At level 50 each increase in grade adds 2 stat points to your monster except A+ to S which adds 3 points. So the difference between E- and S at level 50 is 31 points. (Changed)
6. If you do not have much silver, enhance your main monsters to the lower grades first as the higher grades really cost a lot. About B grade is decent for ladder and pvp. More monsters will also be needed to enhance to higher grades as most of them only give a small fraction of higher grades when used to enhance as compared to the lower grades, where a single monster allows you to skip a few grades in all stats.
7. Price of enhancement. Here's how much silver you need to enhance any monster of the same rarity:
