Weather effects besides rain?

[1Erik1]

What does specific special weather besides rain actually do in a dungeon? Is there a benefit beyond xp in exchange for a higher challenge? Or is special/worse weather only meant to be a benefit for Mag exchange?

[Freya Crescent]

Any of the Purple weathers will cause your crit/weak hits to still consume full Turn Icons, and gives a % increase to XP and A-EXP from battles and overworld kills for the length of that dungeon.

All bad weather does the same thing. Increased rewards, increased difficulty, all deck-based activities on Gauntlet Runner inaccessible, better Mag:Gold rates and all player actions consume entire turn icon (no half turn generated from crits or weaknesses).

More than anything else, that last one is the killer.

The rewards aren't really worth it unless you're farming Overworld combat in the dungeon, the inability to hit weaknesses to not use a Full Turn Icon makes any hard fight unnecessarily harder and usually ends up with you getting worse rewards due to not getting the Unscathed bonus.
