Whereas standard automatons are immune to the Vigor's charged effect, Patriots can be pulled with Undertow. In addition to these effects, Motorized Patriots take damage when struck with Undertow. It will, however, stun them and increase their vulnerability to damage.

Undertow cannot be used to push back automatons. The Siren, on the other hand, is immune to this Vigor's effects. Likewise, Firemen and Zealots of the Lady can be killed instantly if thrown off the city with this Vigor. The latter, however, are only thrown back half as far when casting the Vigor, due to the Beast being a Heavy Hitter, and though Undertow's effects are halved on Handymen, it is nonetheless the only Vigor capable of stunning one. Undertow's charged mode is particularly effective at taking down priority targets such as Snipers and Beasts.This is especially effective when assaulting a barge, as a single cast can send its contents flying to their demise. In addition to its defensive capabilities, Undertow is particularly effective at killing enemies instantly by punting them off the edge of Columbia with a simple cast.Undertow is excellent at alleviating tension in fights, especially when surrounded, as it will clear the area in the player's immediate vicinity and offer an escape opportunity.Enemies can be pulled into Possession traps, which can be easier to get enemies into when pushing or pulling them in.Enemies can be pushed or thrown into a Return to Sender trap for heavy damage, though the trap is rather small.The Vigor can also be used to move targets towards Bucking Bronco traps, and can be used in conjunction with Charge or Undertow to pull or push enemies towards them. Enemies levitated with Bucking Bronco will float away when pushed with Undertow, allowing the player to send enemies over the edge of Columbia much more easily.Undertow can be used to push enemies away when surrounded after using Charge.Undertow can also be used to send enemies into Devil's Kiss traps, dealing heavy damage to them.
