The dual spawning weapons look like they cap out at 12-16 gems, which I’d have to assume (or at least hope) means that many total since 16 of each would be utterly broken, so the chance to be in a good position after casting will be about the same as Anthea or Stonehammer, which doesn’t bode well for them being usable. Some also look way more usable than others… for example, one is boosted by having beast allies (of which there are 63 in the game, Warden hero makes 64), whereas the others are restricted to a specific kingdom or type that would be difficult to make a synergistic team out of and some don’t currently have a hero class for them. Maybe more classes are coming soon, but I’ve never seen a class from a kingdom very soon after its release, and one of the kingdom specific boost ratios is from Shentang. I never really cared for dual spawners for use in teams where I intend to have a plan to win - yeah, they can pull you out of hole even on a bad board sometimes, but the winning strategy is usually not to be put in that hole in the first place, which they can also easily do no matter how favorable your board is. Might be fun to build around for a little bit and have some extra shinies to collect, though.
The tomes could potentially be very strong with their random skill buff, but I was hoping they would be more control oriented and lower mana, but I suppose it is for the best since the hero can be Fast with any weapon and these have a very strong support effect. None of them allow for any new loops, since they all share a color with an existing universal converter for the same color, so it remains to be seen if any will be better in practice than what is already available at endgame, since a consistently fast start often matters more than being able to buff up your stats to ridiculous levels. Depending on their difficulty of acquisition, these could be a huge help to players who haven’t pulled their epic color converters yet, or even as a replacement for them in some cases (alch/fire tome, giant spider/nature tome).
Oh, and mystery egg looks neat. Wonder if it will be 50/50 stryx/dragon or just a random troop between both pools, because there are a lot more Dragons than Stryx.
