(Some guardians go with two-weapon fighting with their gauntlets to get more stickyness at the expanse of less AC, but that would require a feat and possible DM call. Since we're not talking specific builds, just fairly baseline options for the subclass, I left it out.
Infiltrator: Two attacks of d6 damage, +5 Ability mod, +2 weapon, with an extra d6 added to one. ((2 x 10.5) +3.5 = 24.5 ) and a bonus action zap from the homunculus at d4 + 4 proficiency bonus (6.5). Total 31.
