how edit drops chest

1) find the mob number of chest(yes, Any chest its a just mob)
2) set to MobsDrop in Terrain File(example World23-terrain.scp(its a Forgotten Temple) number needed for you item, and set droprate 4.00000000000000000 - I make same for Manticora and Dark kizmiak drops in Porta Inferno
3) Live Example
[MobsDrop] TerrainIdx SpeciesIdx ItemKind ItemOpt DropRate MinLv MaxDropCnt OptPoolIdx DurationIdx
0 0 649 1214 0 4.00000000000000000 1 0 0 0

0 - Number( after 1, 2, 3 etc)
0 - always setted to 0
649 - Legacy Chest(mob number)
1214 - Upgrade Core(Highest)
4.00000000000000000 - Drop Rate (always will be drop uchh, if you dont add other items, if you want first items rare, second more, set randomize DropRates)
1 - min level for drop
0 - too always 0
0 - PoolOpt(if want items with randomize Craft, Craft+slot, etc)
0 - duration (ex 5 for 10hours duration)
i think you all Understand =) you an experience player/dev or eho idk =)))
Good luck!
