There are a few changes made to the Combos rules,
To make a combo every charm in the combo needs to be eather combo ok or combo basic. the ex cost is the minimum abilities cost plus the minimum essence cost of all the charms in the combo.
You still can only have reflexive charms with Combo Basic can only be shared with reflexive charms
Combo Name: Cant hit me
Charms: Seven Shadow Evasion and Reflex Sidestep Technique
Cost: 10 xp
time: 30 days
If you whis to add onto the combo the cost is one xp for each charm in the combo already and the cost of the new charm.
want to add Accuracy Without Distance to the above combo the cost would be 10 xp the time would be again 30 days
