(Unsure if there's a better topic for errata submission)
Gecko Tape Gloves state:
You get to use assisted climbing (p. 93) when you’re wearing the set.
Page 279 for climbing gear also mentions this rule:
This is a backpack with 100 meters of rope (400-kilo test), an ascent/descent harness, gloves, carabiners, crampons, pitons, and so forth needed for assisted climbing (see Climbing, p. 93).
There are no rules for assisted climbing, or any mention of something similar in the description of Climbing on that page, and nothing in the backup tables (At least, on my Jan 2019 copy). I can't find it in any errata files posted so far, but I could've missed it. Most likely, this rule is a reference to "assisted climbing" in 5e that was taken out in 6e.
In the moment, we ruled gecko gloves as a +1 bonus since I didn't feel like checking through the 5e book for a 6e rule and that seemed fair for 250ny gear. However, the intent for this was
most likely to match up to the 5e bonus of +2 and increased speed. It's possible that granting edge might've made more sense in this edition. Player got 7 hits anyways against threshold 3, so they weren't hurting for that extra die.
