Slayer is weak to Ice spells... meaning that Robin and Altina could do some real damage to it. My party consisting of Simon, Aka, Robin and Altina usually took care of it in 3 rounds.

I would start with Aka using Forcefull Lunge on one of the Eaters and Simon using Precise strike, Altina using Ice and Robin using Ice Lance on Slayer. Since all 4 of them hit BEFORE monsters, that should take care of close to half of Slayer's points [not counting possible crits!] and with a little luck kill a Eater since Aka does have 25% of hitting a crit [which will kill a Eater]. So provided RNG is nice and spread damage on all characters you should have little problem completing a fight. Just repeat the process [have Aka strike the same Eater if he's not dead, if he is switch to the other one] and by the end of Round 2 Slayer should either be dead or very, very close to it [400 HP or less].
