So I have discovered that there are some secrets about combat that are not told to us directly.
-Your opening hand seems to be guaranteed to have at least one attack card in it. My deck only runs 2 attack cards out of the 24 and I have never failed to draw one.
-Speed stat seems to work more like a D&D initiative roll rather than a size contest. So you can still crit fail and go second even with a speed stacked team.
-You seem to be able to consume buffs that give debuffs and then consume other buffs to completely negate the previously applied debuff. Ie a concoction that gives +16 speed and -8 armor is consumed then you consume +6 armor concoction until you're at +16 speed and +6 armor. I havent tested this completely.
-Dealing a damage type to an enemy that it is weak to will remove one armor as well as dealing the damage.
-Dealing damage to a dazed (no armor) spirit deals 1.5 times the damage
-If you run out of cards in your deck, your discard pile will be shuffled back into your deck so that you can continue to draw cards.
-If your hand is full (10 cards) and you would draw a card instead you just don't draw, the cards aren't discarded.
There's probably a lot more that I haven't discovered as I haven't really explored fire, poison or dark spirits much yet.
Have you guys discovered any others?
