Servant/slavemasters

For starting values i'll assume you dont really have other units, if you do, figure that out:)
Starting values

Dual lane

lvl 1: 3 upped slaves - 465

lvl 2: 4 + something else is enough, but usually 5 slavemasters is the goal, makes 3 simpler and you hold better. make the small servants way behind on the wall so they dont die, unless enemy sends then you can pull these fron to help out the slavemasters

lvl 3: 7 slavemasters - 1085 value, you might still have more servants at the back to give ''free'' gold, depends on how you wanna go about it.

lvl 4 is a bit harder, you might consider what plans you have at this point, but you'll start losing some masters at this point unless you have other things. if you wanna keep the most possible maybe get 10 slavemasters by this point. But honestly.. it differs a lot by game

Sololane

same principle. 3-5-8 slaves 1,2,3

at this point if you are all melee units, you're more likely to mess up. you'll have to make a choice, do i keep slaving for 4 and get a sera to surge on lvl 5 to cover that level and make a few more slaves? or do i reroll and just take what i have atm. in some cases you could push less to make sure you get some more slaves before rerolling.

Nothing is ever for sure, but slaves makes you really strong/scary on 14 especially, making it very hard for the enemy to send as your teammates can just cover other levels.. However dont play slaves with melee. you can, in the early game, but quickly you'll need something else, and this is after lvl 5 at the latest if you decide to seraphim

Perhaps in future can add some pictures if necessary. If someone makes something more detailed, great, i'll just delete this:)
