I actually lucked out and managed to get my first portal (Azart Hatchery) while starting off with my green dailies. I had just finished with a set of basilisks in Sienna Canyon when I noticed a Wandering Caiman with only a small amount of health left (it had probably spawned from one of the first BAM’s to go down and was in the middle of the others I was fighting).
I can confirm the level XP and skill advancement XP are really good in these (so many fails in this video though since I had to quickly run OBS and noticed it again failed to capture audio; the other fail in here is not having one of my key buffs up).
I started off just a fraction into bar 3 and once this was completed, had filled half of it. The party mode version gives better rewards (probably both drops and XP) but as noted, is also more difficult and mob damage and health scales with each player in that party. My 100% rapid XP boost had also gone to waste earlier when the server went down shortly after coming out of the maintenance that had deployed this update (having that active would’ve probably filled out that entire bar).
Hopefully the RNG on this portal spawn isn’t on the extremely low side because this is a nice alternative to leveling up. Plus there is a level of dopamine fix when you see that portal. I’m going to test the various mob types to see what the spawn rates are like.
UPDATE (better video)
