That's the great thing about this game, yeah it's got exploits, but if you use them you end up getting targeted by everyone else's exploits.
I'm no better. I have my Grimeling farm going as we speak. Grimelings are, as any spellcaster knows, the results of a failed summoning spell. They count against your summon limit, drain mana like normal summons, and are otherwise enemy summons, attacking you and your allies.
So all I needed to do was lead some Goblin Spirit Summoners home, put them in a lockjoint paralysis loop so they stay in my base, use a psionic metrignome from the SCP region of Grandax to force them to keep using Summon Greater White Sheet Ghost- and of course, Goblins auto-fail white colored spells- creating one or two Grimelings. So now we have a constant production of somewhere between 1 and three Grimelings per GSS per three-minute combat time unit (CTU), each one being sucked into a pit by a Grav Vortex so they don't attack the GSSs (the GSSs aren't affected by the GV because of the lockjoint loop).
Now, normally that means I'd only get three Grimelings at a time per GSS, and they're hard to lead all the way through Sucoban and everything. So I added a step where I have a perma-summoned Manabeast in the pit. They have immunity to magic, so I had to build a little fence around it made of Eternity Tokens. Manabeasts are super hard to deal with for mages because they have Untie Binds which makes summons into neutral, non-associated summoned creatures. So he keeps Untying the Grimelings as they get pulled into the pit.
Of course, you know where this is going. Whenever I need a swarm of thousands of Grimelings, I just desummon the Manabeast, and cast Claim Summon with the Cold Casting feat- which makes it an ice spell- then the Thundersnow Stone, which changes ice spells to do +1 electrical damage, and then use Chain Lightning Effect on the Claim Summon, causing it to do less damage per target but spread to all available targets. So it ultimately does no damage- and note here that IF the Grimelings were actually normally summoned, there would be a 0% chance of success for each one. Since they're unowned, it auto-succeeds.
So now I have however many Grimelings in the pit, owned by me, powered by nobody. order the Grimelings out, resummon the Manabeast (consuming an younger shard for the perma-summon, so that 150 credits there), and go on my merry way.
Since Grimelings have drop low-level vendor trash like one copper pence or a Oily Rag, If I just let them all die and collect the loot, I can do that once an hour and gain 150 credits.... or I can wait a couple days and build up almost 15000 Grimelings. They have 5 HP each and have a 1 damage Basic attack, of course, but there's 15000 of them...
Quantity has a quality all its own.
