This my version of rule for Combat Rp (before combat)
1.No character is perfect or untouchable. No character is master everything. Everyone has a weakness or a weak point
2.Every attack or spell has a cost whether it be stamina (physical attack), energy (magic, supernatural, energy attack), or ammo. Both stamina and energy can be recover over time. Stamina recover faster than energy because you're not using your life force for it.
3. Every weapon, armor, ammo, item, equipment ete has weight. No character should able to carry infinite item. The more weight your character carry the slower they move and the more stamina consumed in battle.
4. stat no character is good at everything
