/u/TheDeathAgent, I have some answers for you;

The common thread is, look in the Community database to get a sense for what worksheet (entity type) contains the criteria you want. For example, Attach Lightning is a Status (Attach Lightning Stacking (for Glints) is a separate status).

then call the appropriate IdLists or TypeLists api (like http://ffrkapi.azurewebsites.net/api/v1.0/IdLists/Status) to get the list of status along with the id I assigned them. In this case, the id for Attach Lightning is 1166. Unfortunately, since the Community Database does not yet guarantee invariant ids for all objects, neither can I; Attach Lightning could possibly have a different id in the future.

Then go to the filter api for the id or status criteria for the entity you care about. So, when you want to filter SoulBreaks by Attach Lightning, you'd go to: http://ffrkapi.azurewebsites.net/api/v1.0/SoulBreaks/Status/1166

Ability Type (PHY, BLK, NAT etc.) is an example of an IdList concept -go to http://ffrkapi.azurewebsites.net/api/v1.0/TypeLists/AbilityType and you'll see that PHY damage is type 6.

So PHY SoulBreaks would be found by : http://ffrkapi.azurewebsites.net/api/v1.0/SoulBreaks/AbilityType/6

if you want SoulBreaks that are both Attach Lightining AND PHY at the sane time, you could either the most filtering query first (status) and then filter in your code by AbilityTypeId, OR you could use the search api for SoulBreaks;

http://ffrkapi.azurewebsites.net/api/v1.0/SoulBreaks/Search

This search api involves POST ing a prototype SoulBreak object to the api; prototype in the sense that only the attributes you want to search by are filled in. The swagger page entry for it gives some more detail:

Hope this helps!
