In PSII you can find "Slugmess" (mainly in Roron and Climatrol underwater passage) and "Blastoid" (Climatrol installation) enemies that can self-replicate, clone, split, whatever you want to call it. They produce a new enemy with the same HP as the one performing the action. I was wondering, does anyone know if there more of such enemies? I like them a lot. I spent the evening hunting them and then keep the fight going until I was out of tp's and healing equipment and simply had to finish the fight. Nice EXP and MES! And an excellent opportunity to level characters you rarely use in that stage (in my case those are Hugh, Kain, Anna and Shir). Especially Blastoids, they yield more XP and MES but their damage is laughable. I think with a four character party, fully stocked with trimate I would be able to last a full day in battle against those (with my current level for Rolf being 17, Nei 34 and Rudo 15, but he's at home now, taking some rest so Nei can get more XP).
Right now Rolf en Nei are hunting Blastoids alone in the Climatrol, I want to see if I can crank up Nei to level 50 before I go to Neifirst. With all the money that will be yielding I should be able to buy the entire laco arsenal for my troops at once, once I'm off to Dezo (especially because the dams still await before I can go there).
