is Titan Slinger really as limited as it seems?

[Blissey1]

Rules as written, it seems it applies only to the Sling weapon and nothing else. However, I can't imagine its intended that special feat for halflings to use slings better would not apply to the special sling that halflings get, the halfling sling staff. Is it really only slings and nothing else, or is it sling weapon group?

[Squiggit]

One of the unfortunate side effects of having a collection of weapons and a specific weapon both referred to by the same name.

IMO, weapon group, for similar reasons to how crossbow feats are supposed to work on all crossbows and not just the specific weapon crossbow.

But this is firmly an "ask your GM" question right now.

Weapon group (in my games).

[Themetricsystem]

Pretty sure it is talking about the entire Weapon Group despite how vague it is since the group and specific type of Weapon are identically named.

For what it's worth, Archives of Nethys, in the feat description, hyperlinks "sling" to the weapon group not the specific, individual weapon.
