1.1.1 Released !

Update targeting Sword & Shield Den raids
  • All Dens toggle — Press X to switch between active Dens only and all 276 Dens across Wild Area, Isle of Armor, and Crown Tundra
  • Full info for inactive Dens — Inactive Dens now display species, stars, type, level, and shiny prediction, just like active Dens
  • Event Dens labeling — Event-only Dens slots now show "Event" in purple
 
This is incredibly useful and I wish it existed earlier. The way S/V makes you grind 5 and 6 star raids just for the chance to get a Herba Mystica when they're so incredibly rare and difficult to beat (not to mention required for one of the quests in the game) is really frustrating.
 
I will release soon (today or tomorrow) an updated version that display the rewards in the Tera Raid details view, since we can calculate them based on the seed (fixed rewards and "random" ones).

I just need to test it to be sure that the data are accurate before releasing.

1.1.3 Released !

SV : Reward Preview

  • Added item drop preview to raid detail popup, showing all rewards (fixed + lottery) calculated from the raid seed
  • Rewards are split into shared, Host-only, and Joiner-only sections
  • Rare drops (Herba Mystica, Ability Patch, Ability Capsule, Bottle Cap, Gold Bottle Cap) are highlighted in gold
  • Detail popup widened to 3-column layout: Stats | IVs+Moves | Rewards
SV : Shiny Counter
  • Added shiny count to the raid list header (Raids: XX - Shiny: XX) per map tab
SV Bugfix : Trainer ID
  • Fixed incorrect TID display and shiny detection — was reading from wrong offset (0x04 instead of 0x00) in MyStatus block, affecting both save file and live mode
1.1.4 Released !

SV Tera Raids — Filtering
  • Raid filters: Press X to cycle preset filter (All → 5+ Stars → 6 Stars → Rare Rewards), press Y to toggle shiny-only filter
  • Filters compose freely (e.g., Shiny + Rare Rewards)
  • Active filters displayed as centered gold tags in the list header
  • Filters persist across map tab switches (L/R), reset when re-entering raid view
  • "No matching raids" message when no raids match current filters
SwSh Dens — Shiny Display
  • Detail view now shows skip count alongside advance number (e.g., Square in 5 (4 skips))
  • Advance 1 shown as (current) to clarify no skips needed
