Rad's Guide to Beating the Epic Boss

[DG Magneto]

Ok when i reach a reward tier when i get stuck (like at tier 15, personally i like just collecting the epic armour and im only level 39 now so its not like i will actually get to tier 43 and be able to craft the + version) what i do is use two of my own knights (in appropriate elemental amour, like this week its the leviathan, so im using the AA+ (currently level 26) and the Crius + (currently level 22)) on ny main and another, then i hire two friends for a total of 7EE for my first fight to save 6EE to hire another two friends
What im curious about is if im doing this efficiently? Like would it be more efficient if i used 8EE first fight then 5EE next fight (one friend) to get the 100% boost for the first? Or is the way im doing it currently more efficient?

Assuming all knights have equal stats (which they never do)
5 Knights (200% damage) = power of 10 knights and
2 Knights (125% damage) = power of 2.5 knights
12.5 total

4 Knights (175% damage) = power of 7 knights and
3 Knights (150% damage) = power of 4.5 knights
11.5 total

-------- Sidekick knights re- calculation ---------
5/2 (200%) then 125%
Main knight 1 x 2.00 = 2
Sidekick1 1 x 2.00 x .67 = 1.34
Sidekick2 1 x 2.00 x .67 = 1.34
Friend x2 2x2.00 = 4
Total for first wave 8.67

second wave (1.25%)
Main Knight 1 x 1.25
Friend x1 1 x 1.25
Total for second wave 2.5

Total 11.17 for 5/2

4/3
Main knight 1 x 1.75
Sidekick 1 x 1.75 x .67
Friend 1 x 1.75
Friend 1 x 1.75
Total for 4 = 6.42

Main Knight 1.x 1.5
Friend 1 x 1.50
Friend 1 x 1.50
Total for 3 = 4.5

Total = 10.92

After new calculations you can see that it is very close assuming the same gear. Your friends best character will tend to have very nice armor compared to your sub knights. It is therefore recommended you do 4/3 (or 3/4) given you have enough friends available.
