Well, that's a little different because you've built a power tree such that a character is spending near-Pattern numbers of points, which means that they ought to have near-Pattern level of use out of Conjuration. My point was mostly that you get what you pay for, and if a power seems too cheap for what you get then the GM is doing it wrong.
Do you have a website that lists off all of your power trees? I'd like to take a peek at what you do with partial powers.
No I took my site down when my last web game died.
generally I change the power tree for each game any way at least beyond the basics.
Its all quite vanilla stuff though until people start adding their own advanced tweaks like ...
Pattern Base (10)
> Shadow Walking (5)
>> Hellride (5)
>> Royal Way(5)
>>> Follow Shadow Trail (5)
>>>> Pass through shadow without Trace (5)
>>> Shadow Walk from Amber(5)
This was added by a PC who wanted to be the best Hunter in all of Shadow.
So he has some Advanced Pattern powers, like shadow walking from Amber, has some Additional non-cannon Shdow skills , Follow Shadow Trail and Pass though Shadow without Trace but doesn't have any Pattern Lens power or mould shadow Reality. But gets to this for 40 points which is cheaper than the base cost of Pattern.
I allow players to add this stuff in play as they try to extend their powers to do something new, they just have to pay stuff for it and of course actually think of it.
The tree means you can have very advanced power in one area but be almost entirely ignorant of another. Like a Physicist who knows advanced String theory but never really bothered to get more than a superficial knowledge of Newton's Laws of Motion.
