What you do is get the max horde of at least 25, and make sure to stock up on reds and blues. This only meant for the dungeon and I only tried this on beetles. What you do is spawn 15 or more blues and 10 reds. Then plant the blues on a guard marker and the reds on a seperate one behind them. Now the beetles will keep on fighting the blues letting the reds get aa clear shot and you wont have to lose any minions unless if you bring more than 3 beetles at a time.
At the Forge put up to 150 minions into your item. Pause gameplay when the sequence of the minions jumping in appears before any of them jump in. Quit, and when you are prompted to save select 'Yes'. Resume gameplay and the minions will be put in and none will be lost.
Ok first of all you need full arcanium armour you need a full for ok first we start with the brown spawn 35 browns from the pit I don't really know if they have to be fully equipped but mine are the spawn 5 of each of the other kinds then you have to fight to you have to keep repositioning them so they fight then there you go reds burn the stuff green hop on backs if beetle or what ever do not use this help on big monsters rockgiant,troll, slug etc. Only use it for the smaller stuff like halfings and beattles and sluglets this relly helps don't try it without 50 couse the browns wont do there part and will just die then your messed up because you lost lots of minion so blues revive killed ones red burn them greens hop on backs and brown are the barier so the others don't die and there you go that one easy way to win it and you also need to put them all on a guard marker. And if you don't have 50 minions alowed in your hord then make a big group of reds put them on a marker then go up close to the beattles lure them in and get to a distance the reds can rach you fight them they burn them your set to go.
I Don't think of this as a cheat but what you have to do is find one of the four big beetles which are battler (brown), dazzler (blue), magma (red) and, puff (green)then kill it so it will be in your tower's dungen and from there you can fight them any time but it isn't going to be easy if you don't have some minions. Anyway there are 25 beetles and each beetle gives you three orbs do the math and thats 75 minion orbs each time you have a battle well have a good time!
I don't really think this is a cheat but, Ok first what you need to do is find a big bettel that give you 3 orbs of whatever color it is, well fight one of those big bettles and it will now be in your tower's dungen and you can fight it any time you want it may be hard a first but there are 25 bettles in each dungen fight and each bettle gives you 3 orbs 3x25=75 orbs per fight and it really helps out with smelting well good luck with this!
