My thoughts on the overall slot expanders... wow! This will really shake up some builds!
The character builders and app generator authors will be the real heroes this year.
Really happy to see Charm of Brooching back, as it's necessary for high level play and really scarce.
Really like the recent Earcuff of Orbits, Charm Bracelets, Arcane Bracelets/Earcuff, Charm of Brooching, and Charm of Glory sextet that let you take your pick of:
+2 Ioun, +4 charm
+2 Ioun, +3 charm, +1 ring
+4 Ioun, +2 charm
+4 Ioun, +1 charm, +1 ring
+2 Ioun, +3 charm, +1 back
+2 Ioun, +2 charm, +1 ring, +1 back
+4 Ioun, +1 charm, +1 back
+4 Ioun, +1 ring, +1 back
It's worth holding onto all 6 of these tokens as your build moves around, and choosing between different options as things shift.
It's also going to shore up the market on volunteer Iouns (of which I just sold a bunch, sigh...) and volunteer charms, which seems a nice updraft for the volunteers.
As excited as I am about all this, I worry a bit about how many are happening at once, and what collecting will be like for those who miss out on this bonanza.
I hope the 6 slot expanders can be put into a reprint rotation or something starting in 2022 with 1 of each of the 6 tokens above being reprinted each year so long as there's demand.
