So here are the mechanics, it's a Dice battle
You and your opponent have 3 dices, you can put them in 4 categories of acts you can do: Attack, Seduce, Defense, and Magic.
Attack: Physical damage, takes a notch of their health bar.
Seduce: Lust attack, takea a notch of their mental (I suppose?) bar.
Defense: Your defense, if the die is higher than your opponent attack/seduce then you get no damage.
Magic: So far you can either use Endure (increases the die in your defense by 2, so if you put a dice with value of 1 then it comes out as 3) or Shattering which I will never use out of principle (I am still sorry Chloe) so I am uncertain of what it can do but I believe it recruits them and forces their loyalty.
Your enemies spells tend to revolve with Debuffs against you
Lastly if your dice is double of theirs (4 vs 2 for instance) then you do double damage/lust damage but the same goes the opponent too.
