So, I think after lots of deliberation, I'm starting to settle on my ideal 3 minion set up. I doubt I'll be able to run this anytime soon, but the thought exercise makes me smile. ;)
GL's three Minions (As I now bow to Seftons original deliberation that 3 is the optimal number of minions in CB!)
Base 20 HP
Trains: AP, DM, SS
Wears: Corn, AoI, RoBF, EG, BoF
Base 20 HP
Trains: AP, Decay
Wears: HoC, AoI, BoE, CoI, AG, SB, SoC
Trains: HP, PL
Wears: HoD, AoAC, TSA, SC, TG, CML, MGS
This utilises the power of a totally immune RoBF (the only damage that could target the minion, DD or SoD splash will be picked up by PL without the option of the MoD t bypass it), with the obligatory TSA wearing PL wall.
It has the same XP concentration as a single Minion (give or take for the APs, PL and SS...), 33% EO, 33% DD, 33% HP. But on three dedicated minions, who can all wear stat boosting gear (leading to a massive Decay, in order to put AMF to shame).
Incoming damage is targetted and reduced. For DD, MM hits a high AC+MGS wall. SG hits a RoBF protected no AC minion and Decay cries itself to sleep. CoC and FB are spread and all are then reduced (bar MM) by PL.
Physical damage hits a high AC target, which regenerates. Mageseekers are absorbed by PL (and why the SoC is on the Decay Mage).
Decay is chosen over the other DD for two reasons. I don't need to train HP for AMF backlash (as it can never kill a decay mage) and while GA could be a problem (if my DM isn't enough), the decay mage will still do it's job.
Which is to synergise with the constant, but easily reduced by high AC, RoBF. (I'm aware of the ease of spltting on the two attacks, but I'm not really worried about that).
Speaking of a RoBF, it in turn has to hit my high AC minion. Which regenerates. And SoD splash will be at least reduced by the RoBF on Minion 1.
I always have the option of using an EXBow, if ranged proves too much for my Wall, but I dislike weapon NW in CB, and plan to stear clear of having to constantly sink cash into a weapon.
The HoC helps Decay hit first, even though it's second in minion order, to not lose and potential damage from an earlier RoBF burn.
And DM is to take out all those juicy EDs.
So kill slots, TSA/PL walls, Uber Decay, Single Minion XP concentration, the RoBF and no weapon NW. What's not to like? :P
It's just a shame I doubt I'll be able to run this. :(
