The first bug is related to Primordial Scavengers (the little lizards that burrow into ground and get “rock armor”). Water allies active form is swimming towards them and use attack wave animation but water allies won’t do any sort of damage or any hit registration when scavengers are in armor (there is no white glow on hit nor any hitsound playing, scavengers are untouched and at full hp). Their armor just never breaks, so scavengers just walk around freely and attack you. The only workaround to break them out of their shell is to spam cyclone strike or dashing strike, then mystic allies can finally kill them, but this way you waste entire resource bar. It’s kinda annoying to encounter them full pack on entire rift/gr floor or Visions of Enmity portal when running this build.
Second bug - Blue (Gelatinous Sire) goblin, upon killing first goblin with water allies - no smaller goblin spawns afterwards. Probably because the nearest ground for smaller goblins to spawn is already occupied with water allies roaming around.
