I've noticed a few bugs in this build:
* If you use both Focus and Essence Surge in a battle, only one of the two effects expires when the battle ends (the one that's listed higher up on the abilities list is the one that expires).
* If the Enraged Pommel move is used in a combo, an error message of "Error: <<run>>: bad evaluation: his is not defined" is displayed, and none of the player's abilities used in that combo activate that turn (the opponent's turn progresses as normal).
* Essence Surge's card is listing as having a critical hit chance, even though it's not an attack (and doesn't appear to interact with critical hit mechanics).
* Ensnaring Goo does not have its intended cooldown; the attack can be selected and used on consecutive turns.
* Several of the attacks do not seem to calculate their base damage according to the formula displayed in the corresponding tooltip. For instance, the tooltip for Ensnaring Goo's damage lists Strength-based damage and 8 bonus damage, but it only delivers a fixed 8 base damage (before crit and Pain sigil) regardless of the player's Strength.
* Under some circumstances, drawing a card while there are cards selected to be used in a combo will cause the cards to become "stuck". Those cards remain visually selected in the UI, even after the "clear" button is pressed, but those cards don't become mechanically selected when clicked, and they are not used at all when the combo is executed. It might be necessary to clear the combo after drawing a card as an additional step to reproduce this bug.
* The XP bar doesn't seem to be filling up proportionally to the progress towards the next level. The calculation for its fill percentage might be using the wrong variables.
