If you remember the talks from the Splinterlands town halls from way back, "boss fights" was a theme that came up every once in a while.
First from Aggroed, probably, and later on as a question in QAs from time to time.
Now, the land expansion will have occupied plots that will be inhabited by wild monsters that can be attacked to get some type of reward(s) if you win (it will be p2e). We will see if these will be challenging missions like attempting to kill a boss or easier ones that can be accomplished (i.e. farmed) more often. Or if it'll be a combination of the two.
In the meantime, boss fights will come into the Splinterlands ecosystem, but not from the Splinterlands team.
A new boss-fight game is in the presale phase. It uses the NFTs from Splinterlands and you are the hero that leads them in the battle against a boss of your choosing.
The bosses are increasingly powerful from the left to right, but also the level limit on your cards increases.
There is the public test server and I only tried the top boss, because most of the cards I would use are maxed, and the other bosses have lower limits.
You can use 2 summoners (their level is irrelevant), and up to 7 monsters. The rules of the battle are slightly different than on Splinterlands, but you will catch on to them.
It takes many fights and many players to kill such a boss. Stamina is what keeps someone from fighting the boss non-stop, without earning or buying stamina potions. I don't know the rate of recovery for it.
You can see from the screenshot above that I won a minor stamina potion and some FORGE for taking the boss 60 hit points. There is also a leaderboard, thus the points received.
FORGE is one of the in-game currencies of Splinterforge, along with Electrum.
In the presale, they sell CRATEs, which are packs with 5 cards each. They represent items that the hero can equip to improve its stats.
