Some Mixed Questions. (in General)

Alright so I'm getting ready to start my NCB as soon as I have the gear and a definite strat. Now my questions are

1. Is there a way to figure out how much hiring a minion will cost based on a certain MPR. I was going to run a certain strat early on for quick growth then switch to my main strat so I was curious of this.

2. I'm looking for some criticism on my strat I'm designing. 4 minion RoBF team.

Minion 1 - PL wall
Minion 2 - Enchanter, AMF, RoBF, GA
Minion 3 - Wall possibly AMF
Minion 4 - Small Tank or CoC mage. AMF. More of a kill slot.

The lineup is interchangeable. I just know I want to utilize a RoBF and an Exbow. Stay alive as long as possible by weakening the enemy in any way possible, and chip away at their health. If anyone has any gear recommendations or lineup ideas I'm up for any help possible.

1. That would depend on how many minions you have.

Hiring a minion at 3M MPR, for instance, is different with 1 vs 2 or even 3 minions.

It is based upon the xp of your highest xp minion.

2. If you want a good RBF strat, check out Damage Control by Dudemus. It looks very similar to what you have here.

GA won't fire while the PL minion is alive, depending on the HP spread that either makes it extremely useless or... mostly useless.

AMF under full wall armor... why not just go full HP? An extra 1M hp under heavy AC will probably help you more than an extra 0.01 effect.

Exbows are awesome, I want to see more posts about how imbalanced they are, small tank mostly training dex for hilarity.

I'd go Wall, Enchanter, Killslot, PL wall if you have a mage shield for the PL wall(MM Damage is a joke)

Looking at hiring my 4th minion (3 till then) at around 1mil MPR or so. All things I thought about. I forgot about GA again. I've never used it in a strategy before. Should the kill slot be the minion utilizing the exbow?

Yes, kill slot for shenanigans and dying.

Rethought might want to have the kill slot in the back so your PL wall(Provided it has the standard TSA) doesn't die to a random MM poke.
