so before I had a 4 action economy (2 actions, 2 reactions)

reactions could be exchanged for ‘desperate actions’, allowing them to be used on your turn.

Note: At the time I really liked this system

that said, I worry it could make combat take a long long time

Vaesen combat works as follows;

• you get 1 slow action and 1 fast action. You can exchange the slow to gain a fast in its place.
• During your turn you can spend either action. Actions left unspent become reactions usable outside of your turn.
  • Its not explicit, but because of the exchange rule, if you don’t spend the slow it becomes a fast automatically (and thus can be used as a reaction)
• Vaesen turns were nice, fast and snappy - the only negatives were due to zone-based movement (where moving short distances would consume your whole turn, which sucked)
• AND I felt I was kindof always one action short

Possible combat system:

• 1 strong action and 2 fast actions. You can burn the strong action to gain an additional Fast action instead.
• Any actions you dont spend on your turn (i.e. that you ‘save up’) can be used outside of your turn as a reaction.
  • so like vaesen, if you dont spend your standard during your turn, it becomes a fast.
• Unlike Vaesen and pathfinder, lots of things commonly thought of as actions will instead be free.
  • deflections and dodge rolls will be free as well
  • I’ll also include way more interesting standard actions, and Fast actions will essentially be a dash (cannot provoke reactions).
• I might also include Desperate Actions that slow you on your next turn (you lose the Strong action).
• Can also include “refunds” to prevent stagnant play patterns and reward doing cool things
  • E.g. “if you miss, you regain this fast action after your turn”
