[@Rai] another question, how do we use our skills/abilities?

For example, Kuvira "picked"/trained in 
[quote=@Kibaro]
[center][b]Abilities/Powers[/b][/center] 
1. [i]Bleed resistance[/i]

2. [i]Rock hard hide, claws & dragon wings:[/i] Kuvira can also control the thickness and resistance of her exoskeleton at will, at full capacity, her body - except for soft regions like the eyes or mouth - literally becomes stone  for a certain period of time (around 10-15 minutes) and can sustain a few gun/rifle shots in succession before it starts to break down.

3. [i]Strength Boost:[/i] Her body is also like a mountain, both in strength and resistance. Her muscles force is enough to break boulders with bare fists (it can hurt).

how would those manifest? are those passive or do we need to "activate" them, if so, how long would the activation remain? x number of hits? depends on RP and dice rolls? please let me/us know
