Ok, so before I start. Most skills besides Attack and Guard in my game gain TP. Characters lose 2 TP per turn. If TP gets above 40, the character can't move until it's below 40. If TP is managed effectively, it can stay relativly low
Anyway. Physical attacks gain the most TP. Also, there damage is reduced the higher TP is, but don't have any other restrictions
Most Magic attacks gain less TP, the majority being at 2. However, Magic attacks also cost MP and have cooldowns before they can be used again. Also, there damage is not affected by TP
I plan on making more differences, but wanted to know what people thought before i added more
