One of the concepts I am experimenting with is the idea of actions as a resource to manage in combat. In concept the sum of your IQ + DX (adj) versus a table shows how many actions you get to use in a combat turn. Those actions could be used to Attack, dodge, parry, move etc. as you wish during your turn--but for each action you spend 1 point. No points means no more actions to be taken this turn. Note some skills if mastered add an extra action--but only to be used with that skill. For example a Sword Master would get a bonus action--but it could only be used with the sword (additional attack or parry--not additional move or dodge).
Generally characters would have 2 to 3 actions, but master a skill (or high attributes) would add additional actions above the average...which kind of fits with the idea of the super agile, quick witted or highly skilled/ trained character/ opponent being more deadly/ creative/ hard to kill in combat.
The work continues...
