Not Lock-on distance... The distance where you can Lock-on is actually greater than any Ranged Weapon. ( However , the Projectile Arrow/Bolt is increased via this Talisman ). You just simply gain like 5-10 points of Range when equipping this Talisman.... Not worth it for me but this Talisman is pretty good with Ballistas mainly , and 1 Greatbow imo.

None of the above.

It increases the range before certain projectiles get damage falloff.

Reply to a reply 26th Aug. Assuming I haven't misunderstood, the lock on distance is NOT greater than any ranged weapon. I use bows to proc bleed / poison on the blistered crows and they can close with you alarmingly quickly, they're right on top of you in a matter of seconds. I get a lock on them then slowly back away until I lose it then shoot from the limit of its range and I hit them every time. All the longbows and greatbows land shots at the target-lock's limit.

It doesn't technically affect damage, period. You probably just got a stealth hit or something.

I believe it affects the damage fall off for the fan knives as well. I tested on the giant in front of Godricks boss room. At the same spot damage went from 24 to 32 with talisman equipped.

kukri gets almost infinite range from it, for some reason

Doesn't change it , Lorettas GB and Mastery are 2 of the Biggest Ranged Spells from within Elden Ring. ( There's no need ). Since those Spells are considered purely Magic even tho mimicing a Greatbow Shot... Just tested this also. It seems also this Talisman only affects Physical related Projectiles specifically. ( So even Ice Spear AoW doesn't benefit , altho Spectral Lance and Beast Roar is affected by this since those 2 Skills AoW are Pure Physical Throwables sort of lol ).

Interesting, I wonder if it works with Cannon of Haima

No , i tested everything with this Talisman.... Actually this Talisman only Affects Physical motion related Trajectory of Objects.... Altho not all of them either. ( The Skill Spectral Lance , Beast Roar gain increased Range altho not Ice Spear since its Ice/Magic... ). Rock Sling is rather pure Physical even tho Casted as a Spell , the Rocks deal substancial Physical & Stance-Damage which is why they are Affected.... However , Stone of Gurranq seemed to gain alil bit of distance similar to Beastial Sling. In the Sorcery Spells only Rock Sling is affected , it seems to be rather an unusual bug or maybe just a Miscalculated Fix prior idk not sure lol. But enjoy.

Nearly certain that it works with great oracular bubble (spell)

The only spells/sorceries it effects are rock sling, ambush shard, and the big bubble.

Indeed. Tested with Black Flame and Giantsflame and it affects both, positively.
