eyy blaseball username!
i haven't tried doing geomancer without killing the sappers first, but blink stones and haste potions (and/or their exotic) could be a big help in getting out of the way quick. a scroll of affection or rage might be good too to distract the minions from hitting you. you might want to save the bees for the actual bosses but they could probably work here too on the minions.
i'm trying to complete the catalog since it came out and i have no idea what this one (squared off in red) is. i'm pretty sure the other one is the rogue's shadow ability (just haven't gotten there yet) but feel free to correct me on that if i'm wrong.
thank you!!
