Journey with the Shadow Summoner to unlock all 4 Elementals and attempt the Great Summoning in the Free Spins.
There are 4 Elementals to be unlocked through collecting wins. For each Elemental unlocked, the player enables another type of feature to trigger. The 1st Elemental unlocks Wild Spread, the 2nd unlocks Explosion, the 3rd unlocks Respin, and the 4th unlocks the Upgrade feature.
With all Elementals unlocked, all four features can happen on any spin, and the Bonus symbol can start to land as well. Land 4 Bonus symbols to trigger the Free Spins, where the Shadow Summoner unleashes its elemental power in 4 guaranteed feature spins, each with a guaranteed feature trigger and a persistent multiplier throughout.
If enough wins are collected during a round of 4 feature spins in the Free Spins, the Dark Summoner levels up and conjures another 4 feature spins, with the threshold for the next level up increasing. You can win maximum 4 level ups.
Unlock the 4 Elementals, land 4 Bonus symbols, win 4 feature spins in the Free Spins, and level up the Dark Summoner 4 times 4 the ultimate win.
