Royal Meeting Room upgrage to T3

Can someone share experience how to complete this challenge? May be there is a tricky way to raise chances, whatever? Something, please!

What I do: trying to spawn room on maps, if there is no chance to get room/upgrade->reset temple in harbour bridge->repeat

well not rly just farm maps a lot of them...

the only tip when you get a fresh temple and you dont have your room already in it...

check first alva portal -> both options arent your desired room -> DONT KILL any boss
check 2nd alva and repeat



because in one map the same room cant spwan twice ( you might wanna skip the next alvas WHEN you get your desired room )

All 3 Alvas in map offer the same option. If skip, next map will offer exact same. It predetermined somehow.

If enter in incursion and not kill architects that in the next map Alva's first offer will be the same as skipped too. If open and not enter next Alva don't appear.

It possible upgrade existed royal meeting room into T2 in world zones, maybe even in T3. But T1 can be acquired only in maps or after temple reset.
