It gets better and better after the tutorial as you'll start unlocking lots of stuff that allow you more variation in the gameplay.
And now, the definition of frustration.
Managed to clear the 7th scenario (noxious marsh) on hard mode with the demonologist after several failures, was going for the 8th one (the ancient tomb) in the hope to unlock finally the corresponding item.
After a lot of losses (as the scenario is "curse your die faces party" , so much the multivitamin item can't follow at all) i decided to ditch the multivitamin and get the ring of fellowship (despite i had the demonifesto) nstead so at least i could have a chance to have a starting imp pet with the hope to get red gem rolls to kill the starting enemies (as they have 4 health) before they can throw curses.
It surprisingly worked (well not that surprisingly as having much less cursed faces thanks to the starting imp helping with the first opponent before he could hit me at least twice (and curse 2 faces), i was losing less health when rolling them and the many tomb guardians enemies weren't getting +attack bonus that fast).
Then after defeating the demi boss (great i had purchased some good healing faces as she hit hard, more than the final boss,), the final boss appeared.
I rerolled a lot and thanks to the many red faces i had purchased for my army of imp, we defeated his minions and hurt him bad.
Unfortunately i got a lot of hit too and faces withered.
So on the final attack i finally cleared it, the boss was destroyed.
Happy, i pressed Next Turn and :
Huh ? you got to be kidding me , the game just killed me after i ended this victorious turn ...
It's probably a bug as i am sure i had 2 health left when i pressed the end turn button. But damn, just when i was finally going to clear that horrible hard mode "Ancient Tomb"
edit : finally cleared the hard mode version of Ancient Tomb, i think i was on the right track with my item choices
It allowed me to finally unlock the item rewarded for clearing 8 hard mode scenario.
Then i read the description of the item
You can use abilities with no charge.
that sound super awesome, but
Each time you do, gain 3 fear
That seemed to make it the worst item ever.
Until i tried it and the 3 fears are only used when you want to use an item that has run out of charges (as the item prevent abilities to disappear when they have run out), so not so bad after all, and even really good on scenario that does not feature fear-giving enemies.
