As you may suspect with hammers, both of these weapons dish out most of their base Damage as Impact. Heliocor is the second strongest Hammer in the game, with a Base Damage of 140, with Synoid Heliocor further down the ladder at 120.0. Heliocor also boasts a higher Crit Chance at 25%. Trading in the Damage and Crit Chance, Synoid Heliocor swings with a higher Attack Speed and Status Chance at 20%.
One of the key traits of both hammers is that they perform Codex Scans on fatal strikes. These will consume scanners, so keep an eye on your supplies until you have the Synthesis Scanners with the Sol Battery Widget. Keep in mind though, these count as Codex Scans, not Synthesis Scans. You will not earn Simaris Standing while using these weapons. Also, they cannot be used to “Scan” Simaris Targets, but they can be used on Feral Kavats to obtain Kavat Genetic Codes.
Like the other Syndicate Weapons, Synoid Heliocor has a bonus ability. In this case, it will create a Specter of an Enemy when slain with a Channeled Attack. The spawned Specter will have a Duration of 30 seconds and only 1 may be active at a time. Any other channeled killing blow will not spawn a new Specter until the existing one dispels. Unique enemies such as bosses and wild enemies such as Feral Kavats are also restricted from spawning Specters. When spawned, the Specter can be told to Follow or Hold Position, much like gear-wheel Specters.
