Jeff, thanks for removing the Polymorph Familiar tokens! I think the way you plan on addressing it in 2021 is a far better way to go.
The Wizard Legendary is still extremely powerful, I think overly powerful. And every single ability is aimed at increasing the amount of damage the Wizard does, who is already one of the top damage dealing classes.
1) Ability to use any 5 scrolls as spells, lets the Wizard situationally choose the best five scrolls for any particular Dungeon, including elemental vulnerabilities, without consuming them.
2) Bonus Spell box at each Spell Level, which can be cast as instants. This is huge, it's not only extra spells, but gives the Wizard the ability to cast two spells per round, nearly doubling damage capability on those turns.
3) Medallion of Mystic Mouth built-in gives them free action Wand usage when not using free action spells, especially valuable since it is also neck slot.
4) Mad Enchanter's Charm: In my mind by far the most powerful and broken UR ever printed, significant extra damage every time it's used.
Compare this with the very underpowered Druid Legendary, which almost certainly gets less of an increase from the Relic than any other Class Legendary (the below is borrowed from Phillip Goodman). The summary is that the only real bonus currently from Relic to Legendary for the Druid is an average damage wheel increase of 1.5 points, which is insignificant.
1) 1.5 average damage increase on damage wheel
2) Can cast spells while polymorphed (useless since you can already unpoly -> cast -> poly every round from the Relic)
3) Polymorph potions, if used, don't have to be turned in. This would be a valuable ability if there were any worth using over the Elemental forms, but there aren't.
4) Even the ability to Polymorph into Elemental Forms from the Relic are underwhelming, it still puts the Druid fairly low on the damage dealing spectrum.
I'm putting this here because there isn't a separate thread for it. I would request the Druid Legendary abilities be modified as follows, to make it at least in the ballpark of power level of the other two Spellcaster Legendary tokens. This would not require any changes to the actual token or any sort of token exchange, they can very easily and quickly be made in the Tokendb.com entry.
1) Also give the Druid an extra spell box per level that can be cast as instant. The Druid class is going to fall far behind the Wizard class without also having that bonus.
2) For just the Legendary, remove the restriction of only one polymorph form per room. That restriction was added on at the last minute, and I think it was a mistake. The main argument for the restriction was that the Druid could attack as one Elemental form and defend as another. That comes into play in a small percentage of rooms, and even with those it isn't a huge advantage. A Legendary polymorpher should be able to do more than one form per room, just for the fun of it.
3) Modify the Elemental bonuses so that they're not just simply damage resistance. In particular, the Air Elemental form should have Flight.
Now is the ideal time to revise the Druid Legendary token, because the URs for it are still available as PYPs. I think the three spellcasting classes should have been done in the same year to start with so that they could be made consistent, so revising the Druid Legendary now is a way to do that.
