Power based on two rolls

[HeroGM]

Can you plug in a power that uses two different skill/stat rolls? 

[Greywind]

No.

Goes some things from APG

Custom Modifier for the second Requires a Skill Roll, since it's not part of the core rules (i.e. the core rules allow only a single instance of Requires a Skill Roll).

Custom Modifier is your friend.  It comes in very handy from time to time.  I defined a High Scale movement advantage that's principally for Running and Flight, because MegaScale is too much IMO for the continuous movement powers.  From APG, there's Damage-Based END cost that I also like a lot.

 

There is a fair bit of stuff in APG not included in HD, but it can generally be included via one of the Customs.  Defensive Attack's a nice one for a Multiple Attack specialist;  it's got to be a custom skill.

Ok. Looking back I think there was some confusion.

 

Say you build a mental power that has two costs to it. CostA is control and costs 3pts plus +1 per 2cp as a normal skill,  meanwhile costB is 5 cp for 1d6  and +3cp for each +d6.

You’re defining something that is outside of the rules of the system — the same answer applies.  Custom Modifier for Limitations/Advantages that are outside of the core rules, Custom Power (or create a custom template) for Powers that are outside of the core rules.

If “costB” is a standard Power, then just purchase it as such.  If “costA” is a standard Skill, then purchase it as such.  If “costB” requires a successful roll of “costA” then assign RSR to “costB”.

After typing it I was thinking compound power. I really need to find that listing in apg 1 or 2 that has what I'm talking about in it.

Please be aware that you're posting in the HD forum -- this is where you can get help on how to do something within HD...but you haven't really defined what you want to do -- use a different forum for that.  Once you know the rules that you want to use to model the ability that you're after, if it's not clear how to do that in HD, then you come here.
