Fair question.
We ran Legacy of the Orc Warlord today, with the Monk cards. Gave them a good test. To regain Mind points, the Monk needs to meditate for two rounds to regain one, or can land a critical strike. My critical strike rule is when using a standard weapon, you roll all skulls (not possible on single die roll), so get to roll skulls again. Did roll 6 skulls for a critical attack today.
My Monk has Counter Strike and the Reaction Strike ability, so I managed to damage and kill quite a few monsters, but only landed two critical strikes.
My reasoning for the way they work, is I dont want the Monk to be too overpowered. The skills are awesome, but as they are always available, something has to restrict their use. Hence the Mind points.
There are a few options (could have Attack and Defence change on the one card) for varied situations. I used Winged Warrior today to allow my kids characters to stay protected, although my sons Battle Mage could get higher Def than me, it takes him longer to buff up. Helpful skill at the time, but could have been more aggressive. I play a more strategic game however.
After the test, I am fairly happy with the way it went. Want to make another Ki Power that allows Two attacks per round, but havent thought of the name yet, or found a decent image to put on the card.
But feel free to change the skills if you like, and let everyone know how you roll. I'm always interested in how others do things. Might be something I didnt think of.
Or I could just be rambling like a crazy person. I am sick at the moment, and brain not on 100%.
Whatever the case, enjoy your questing.
