It’s completely random. I just try to clear all the rooms and get lucky. I also didn’t donate any Treasures to Hall of Guardians hoard at that point yet, so no bonus from Hoard Quailty.
I think what I got from it is 7,000 goals and 120 chaos orbs or something like that, didn’t screenshot it.
With sufficient Quality in a Treasure Hoard, the Delve Chest level increase for clearing the boss room can go as high as +4 levels (1 guarantee + 3 bonus).
That’s how players can reach max Delve Chest level.
Could not find an answer on my question: “Faction team” is a team with only faction troops (Gargoyle, Silent Sentinel, Arcane Golem, Ethereal Centry for Hall of Guardians; Watch Mother, Ocularen, Ocularen Leech, Xerodar for All-Seeing Eye)? Or can I use Whitehelm and Darkstone troops as well (respectively to their factions)?
I believe changes in resurrection/summon on death mechanics in pet rescue and similar stuff hasn’t been mentioned in patch notes.
Resurrected (like Infernal King) or summoned on death (like Ancient Horror) troops now spawn at level equal to original troops level, though still untraited, instead of weaklings that they were before the update.
I haven’t checked how this works with Goblin King’s summon yet.
Based from the data I see, it did indeed changed without any mention in patch note.
Summon by spell - summoned troop will have the same level at summoner’s magic stats.
Summon by trait - summoned troop will have the same level as its summoner.
Both 2 type of Summons will still capped at level 20 with collection rules in PvP/Arena/Guild War for both sides, but not capped for enemies’s side in the modes that their troops’ levels can go over 20; Raid/Invasion/Pet Rescue/Class event/Delve.
Summon by trait by AI in those 5 modes - summoned troop will have no trait. So Infernal King in Pet Rescue will only able to resurrect once.
Their data are already existed on the game, just random nature make them quite rare. So far there are 3 types of them, you can see one from Ozball’s screenshot, the other two are below.
Are faction troops going to be added to the appropriate Chests after the normal exclusive window of 3-4 weeks. They are dual kingdom after all. The 4.0 release did not state one way or the other.
