kinda wixh you can apply this to plants to get Biollante. granted i imagine you can bend the rules a bit with any template, i believe you already did yourself with a previous one, but still.
i wonder if the lich template is up next, i know mummy, wraith, ghost brute, and wight templates are on the table as well. now to think about it there are a lot of undead templates
i feel like it should state the guardian has to be bloodied to get elite recovery like other elite monsters.
Also Teleport should be an action and not a trait.
since the puzzle golem can go up to large size, maybe make variants that can go up to titanic (who i imagine being the elite version of the gigantic variant). The web golem/web guardian is also a thing from that issue as well.
While i do suppose we're gonna deal with the fiend dragons eventually, from the same issue there are also mummy, wraith, ghost brut, and wight templates from the same issue. We already did a bunch of skeleton templates awhile ago so why not.
i think that blood horses are meant to be fallen celestial equivalent to pegasuses (note how all the fallen angels still keep the celestial tag but are still evil).
The last one can't help but make me think of "Spider-Drake". The Mardallond also feels like it would be THE drake of choice for dwarves everywhere. It would also be cool flavor if Mardallond can just I guess "pour" their mead without spitting it out like a breath weapon so it can function as a...
interesting, more elementals. I also feel like mist wolves should have some ability to see through lightly or even heavily obscured areas more easily as otherwise their own fog breath kinda screws with them.
