Right now there's only one option that you can do to use a skill only once a round. You can pick "Opener" and then set it to "Do not use" and that will work but ONLY if the skill is available.

What would really really be nice is a "Use Once" option for skills. For example, champions like Lydia or Armanz or Fabian. You really only need to use their A2 or in Fabian's case A3 once per Round if you're clearing correctly and like I said earlier, if "Opener" option only works if it's available. It really sucks to see them use a great A2 or A3 a second time at the end of the fight and then not have it available in the first few turns of the next Round.

This would be super useful in many Dungeons but also City and Doom Tower especially!

EDIT: Also (Per SoS) Faction Wars would greatly benefit!
