Snow

Yes it's working as intended; when you get a higher HP DMG Limit than normal, you keep it until you go below it. It wasnt until we could get really high OF values and raised HP DMG Limits to even see it (in summons and how kain can maintain it while in the air) and then BRV retain units like Jecht and Locke showed off being able to do it reliably for an HP attack or 2

Destroth and Theologica (and others I probably don't know about) tested if raising Laguna's HP DMG Limit through similar means and it does indeed allow his Desperado debuff to hit higher than "normal" on 3 enemy fights and lots of HP DMG taken up debuffs so huge shoutouts to them for that discovery.

As for who makes the most use of Snow's BT effect (the BRVgains), anyone can! Especially those without ways to maintain their BRV after HP attacks (so no gains, no retain, no brv gain on crits and such). However, units that DO HAVE BRV Retain, BRV gain and  BTs (or FRs) make the most use of Snow as they cut down some of the work needed to setup and have a raised HP DMG Limit to abuse consistently with the right setup.

A big counter to Snow abuse is HP shields and the Harden mechanic as the brv gains are based on HP DMG and if you hit for 0 because of these mechanics, you will dump your BRV and return to normal until you can raise your HP DMG Limit again!

Snowverflow Setup

This is a case of it being fairly simple to achieve if you have the right pieces. You'll need:

• • BRV Gains up and OF (gained) effects from party member effects (LDCAs, buffs, auras, etc)

  • Snow BT+

  • A Strong BT+ unit to drive the pain train. If they already have BRV gains, BRV retain and BRV Gains up, it makes it easier.

  • An HP DMG taken up debuff (probably from a call)

  • (Later you will need Iroha LDCA)

  • Once you have the pieces, you want to pop your LDCAs, use Snow BT finisher. From here, BT finishers will raise your HP DMG Limit but BRV gains from Snow's BT effect will be so high, you will stay above your normal HP DMG Limit and keep the BT's HP DMG Limit. You will keep this higher Limit as long as you can keep gaining enough BRV to stay above your normal limits.

• A list of BRV Gains effects to partner with Snow thanks to DissidiaDB

• List of BRV Gains up calls also thanks to DissidiaDB

• Extra adjustments may be needed depending on the unit you want to focus on as some units lack the BRV Gains up or OF (gained). HA and HA+ passives may also need to be unequipped depending on reductions.

• Note: As of Rydia's FR Mission Dungeon Shinryu missions now limit BRV Gained and Retained to 30% each of a unit's HP DMG Limit. Before, it was 80% which meant with Iroha LDCA for some Retain on units, Snow could still help Snowverflow but this new change means Snowverflow is no longer possible!
