[Autumn]

In order to stabilize the difference between Korvara and Mainland when it comes to 10 star items, since the +1 upgrade stamp is not available there, there are certain upgrade tiers that become unavailable to certain items there, particularly it is more impactful to the following items I've compiled a list for, everything else isn't quite as impacted. Namely they're the items that scale in increments of 6 instead of 5, which would be more preferable for Korvara without impacting Mainland at all.

Fox Paw - Current effect is UL/6, should be UL/5 to match Korvara

Buzzing Chakram: Attack Range increases by 1 per 6 UL, needs 1 per 5 UL to match Mainland.

Spine Leash: Attack Range increases by 1 per 7 UL, needs to be 6 to match mainland, could also be 5 for slight buff.

Carteblanche: When airborne attack ranges increases by 1 per 6 UL, needs to be 5 to match mainland.

Vorso Verso: Increases Contract Maximum by 1 per 12 UL, needs to be per 10 UL to match mainland version.

Quickdraw: Gains 1 round per 6 UL, needs to be 5 to match mainland.

Dancing Shiv: On Attack: If you are behind your target, inflict Fray LV1 + UL/3, inflict lvl 8 Fray on G6, inflicts lvl 6 on Korvara.

Thunder Hooves: Effect currently grants up to UL/2 charges when moving, effect triggers at 18 charges, to account for 6 upgrade levels of mainland.

Anchor Edge: Attack size increased by 1 + 1 per 12 UL, needs to be 10 UL to match mainland

Hands of the Giant: On Hit: Knocks the target back UL/6 Tiles. (Needs to be 5 to match Mainland)

Overgrown Staff: Creates 1 flower at a random tile per 6 UL, needs to be 5 to match mainland.

I also included items that are not in Korvara yet but for future consideration anyway I included them.
