Overall - pretty good update, no hard feelings about no more healing - stacking armor was way funnier anyway
New Power Boost is amazing and very conductive to be enchanted with Growth
Honestly didn't understand why Vampiric Armor wasn't working until I checked Vampiric Strike's description in the shop
Lightning Armor feels kinda weird? Maybe need a note that it doubles the *remaining*energy. Well, I just abused it for that 30 armor it gives instead
Anyway I'm not sure if it's a bug or the feature of the current balance system, but it's very easy to ran away with it (that's Act 2 boss in two turns):


and I didn't even try exploiting new Counter spells yet...
