for Clarification on the Config, the LootTier is referenced under the hill locations
"m_HillLocations": [
{
"Name": "NEAF",
"LootTier": 2
},

which is referencing Reward Pools
"m_RewardPools": [
{
"RewardContainerName":
"m_Rewards": []
"m_LootTier": 1,
"m_MaxWinningItems": 2,
"m_MinWinningItems": 1
}
In terms of Building out the corresponding Reward Pools per Tier is it:

Multiple Sections of these per tier
"m_RewardPools": []
{
"RewardContainerName":
"m_Rewards": {}
],
"m_LootTier": 1,
}

or these per Tier

"RewardContainerName":
"m_Rewards": [
{
"ItemName":
"Quantity":
"Attachments": []
},
],
"m_LootTier": 1,
}
